|
||
|
||
## 1. 裁判 LLM 强制异构 (P0-1)
|
||
|
||
### 1.1 异构原则
|
||
|
||
主 LLM 与裁判 LLM 必须满足:
|
||
- **不同模型家族** (Transformer 派系 ≠ MoE 派系不算异构, 必须不同训练数据 + 不同 RLHF pipeline)
|
||
- **不同厂商**
|
||
- **不同架构** (推荐 Dense vs MoE, 或 MLA vs Standard Attention)
|
||
|
||
### 1.2 推荐配对 (2026-04 旗舰)
|
||
|
||
| 主 LLM | 裁判 LLM | 异构强度 |
|
||
|---|---|---|
|
||
| Qwen3-Max (阿里, MoE) | DeepSeek-R1 (深度求索, MLA) | ★★★★ 数据/架构/RLHF 全异构 |
|
||
| Qwen3-Max | Llama 4 Maverick (Meta, MoE) | ★★★ 国内训练 vs 海外训练 |
|
||
| GLM-4.6 (智谱) | DeepSeek-R1 | ★★★ |
|
||
| DeepSeek-V3.1 | Qwen3-Max-Thinking | ★★ (同期国产, 较弱) |
|
||
|
||
**禁配**:
|
||
- ❌ Qwen3-Max + Qwen3-Max-Thinking (同家族)
|
||
- ❌ GLM-4.6 + GLM-Zero-Air (同家族)
|
||
- ❌ 任何"主用 X, 裁判用 X 蒸馏小模型"
|
||
|
||
### 1.3 system prompt 签名 pin
|
||
|
||
```yaml
|
||
# judge-llm-config.yaml (受 security-key 签名)
|
||
judge_pool:
|
||
- id: judge-deepseek-r1
|
||
type: deepseek
|
||
model: deepseek-reasoner
|
||
deployment: local # 强制本地, 防云侧投毒
|
||
system_prompt_hash: sha256:<...> # 启动时 hash pin
|
||
system_prompt_signed_by: security-key:csso
|
||
|
||
- id: judge-llama4-local
|
||
type: openai_compat
|
||
endpoint: http://localhost:8002/v1
|
||
model: Llama-4-Maverick-17B
|
||
deployment: local
|
||
system_prompt_hash: sha256:<...>
|
||
system_prompt_signed_by: security-key:csso
|
||
|
||
heterogeneity_check:
|
||
primary_model_family: ${primary.family}
|
||
forbidden_judge_families: [${primary.family}]
|
||
required_diversity_score: 0.7 # 主裁判 embedding 相似度上限
|
||
```
|
||
|
||
### 1.4 双裁判共识机制
|
||
|
||
HARD_ACTION 决策必须**双裁判同时通过** (异构 N=2):
|
||
|
||
```python
|
||
async def hard_action_consensus(intent, plan):
|
||
judge_a = judge_pool['judge-deepseek-r1']
|
||
judge_b = judge_pool['judge-llama4-local']
|
||
|
||
result_a, result_b = await asyncio.gather(
|
||
judge_a.review(intent, plan),
|
||
judge_b.review(intent, plan)
|
||
)
|
||
|
||
# 任一拒绝即否决
|
||
if not result_a.approve or not result_b.approve:
|
||
raise SafetyVeto(reasons=result_a.reasons + result_b.reasons)
|
||
|
||
# 风险分歧过大也否决 (防其中一个被入侵)
|
||
if abs(result_a.risk_score - result_b.risk_score) > 0.4:
|
||
raise SafetyDivergence(a=result_a, b=result_b)
|
||
|
||
return ConsensusOk()
|
||
```
|
||
|
||
### 1.5 输入隔离 (修复裁判 LLM 自身注入)
|
||
|
||
```
|
||
[裁判 LLM 输入]
|
||
System prompt: [SIGNED + PINNED, 启动期 hash 校验]
|
||
─────────────── 强分隔 ───────────────
|
||
Untrusted data block:
|
||
<DATA_START>
|
||
{plan from primary LLM}
|
||
{RAG snippets}
|
||
<DATA_END>
|
||
─────────────── 强分隔 ───────────────
|
||
Question: [固定模板, 不接受动态指令]
|
||
```
|
||
|
||
裁判**独立 RAG corpus** (与主 LLM 不共享), 仅由 ops 离线维护。
|
||
|

|
||
|
||
## 2. 时钟模型重写 (P0-2)
|
||
|
||
### 2.1 v1.2 致命错误
|
||
|
||
```python
|
||
# v1.2 §4.5 错误代码
|
||
def open(self):
|
||
last_ts = self.db.get_last_saga_started_at()
|
||
if time.monotonic_ns() < last_ts: # ❌ 进程重启 monotonic 从 0 开始, 永远 < last_ts
|
||
raise ClockSkewError(...)
|
||
```
|
||
|
||
### 2.2 v1.3 正确实现
|
||
|
||
```python
|
||
# brain/saga/clock.py
|
||
import time, uuid
|
||
from datetime import datetime, timezone
|
||
|
||
class HybridClock:
|
||
"""三层时钟模型"""
|
||
|
||
@staticmethod
|
||
def wall_now_ms() -> int:
|
||
"""Wall clock (UTC ms), 跨进程持久化对比用"""
|
||
return int(time.time() * 1000)
|
||
|
||
@staticmethod
|
||
def monotonic_ms() -> int:
|
||
"""Monotonic (boot 起的相对 ms), 进程内单调用"""
|
||
return int(time.monotonic() * 1000)
|
||
|
||
@staticmethod
|
||
def generate_trace_id() -> str:
|
||
"""UUIDv7: 时间戳 + 随机, 跨进程唯一"""
|
||
return str(uuid.uuid7())
|
||
|
||
class SagaStore:
|
||
def open(self):
|
||
last_wall_ms = self.db.get_last_saga_wall_ts()
|
||
cur_wall_ms = HybridClock.wall_now_ms()
|
||
|
||
# 仅当 wall clock 显著回拨 (> 5min) 才拒启动
|
||
if cur_wall_ms < last_wall_ms - 5 * 60 * 1000:
|
||
raise ClockSkewError(
|
||
f'wall clock went backward by '
|
||
f'{(last_wall_ms - cur_wall_ms)/1000:.1f}s'
|
||
)
|
||
|
||
# 进程内 monotonic 独立计数, 不与持久化时钟比较
|
||
self._proc_start_mono = HybridClock.monotonic_ms()
|
||
|
||
def trace_id_uniqueness(self):
|
||
"""UUIDv7 高并发同毫秒冲突极低 (74 bit 随机), 但仍 PRIMARY KEY 兜底"""
|
||
# PRIMARY KEY (saga_id) 在 INSERT 失败时重试一次新 UUIDv7
|
||
pass
|
||
```
|
||
|
||
### 2.3 时钟回拨场景与处理
|
||
|
||
| 场景 | 检测 | 处理 |
|
||
|---|---|---|
|
||
| NTP 调整 ±数秒 | wall clock 微调 | 容忍, 不报警 |
|
||
| 时区配置错误 (UTC ↔ +8) | wall clock 跳 8h | 拒启动 + 告警 |
|
||
| 虚拟机克隆 | wall clock 同步, traceId 用 UUIDv7 唯一 | 容忍 |
|
||
| 物理时钟硬件故障 | wall clock 大幅回拨 | 拒启动 |
|
||
| **进程重启** | monotonic 归零 | 不与持久化值比较, 容忍 |
|
||
|
||
### 2.4 NTP / PTP 强制要求
|
||
|
||
- 大脑 + Edge Gateway 必须配 NTP 同步, 漂移超 1s 告警
|
||
- 工业现场推荐 PTP (IEEE 1588), 微秒级
|
||
- 时钟源必须本地化 (国内不依赖境外 NTP 池)
|
||
|

|
||
|
||
## 3. 强 schema DSL (P0-3)
|
||
|
||
### 3.1 v1.2 漏洞
|
||
|
||
```yaml
|
||
# v1.2 写法 (字符串歧义)
|
||
- device_class: motor AND param: speed AND value_pattern: "<=10%"
|
||
# attacker 设 speed = 10.0001% 直接绕过
|
||
```
|
||
|
||
### 3.2 v1.3 强 schema
|
||
|
||
```yaml
|
||
# action-semantics.yaml
|
||
schema_version: "2026.04.v3"
|
||
|
||
semantic_groups:
|
||
production_halt:
|
||
description: 任意可导致生产线停止的组合
|
||
members:
|
||
- device_class: motor
|
||
param: speed
|
||
value:
|
||
op: "<="
|
||
value: 0.10 # 数值, 非字符串
|
||
type: ratio # 类型必须显式
|
||
unit: percentage_of_max
|
||
|
||
- device_class: conveyor
|
||
param: speed
|
||
value:
|
||
op: "<="
|
||
value: 0.10
|
||
type: ratio
|
||
unit: percentage_of_max
|
||
|
||
- device_class: valve
|
||
param: state
|
||
value:
|
||
op: "in"
|
||
values: ["closed", "fully_closed"] # 枚举
|
||
type: enum
|
||
|
||
- device_class: agv
|
||
param: command
|
||
value:
|
||
op: "in"
|
||
values: ["halt", "estop", "pause"]
|
||
type: enum
|
||
```
|
||
|
||
### 3.3 编译期校验
|
||
|
||
```python
|
||
# tools/semantic-schema-validator.py
|
||
ALLOWED_OPS = {
|
||
'ratio': ['<=', '>=', '<', '>', '==', 'in'],
|
||
'enum': ['in', 'not_in', '=='],
|
||
'integer': ['<=', '>=', '<', '>', '==', 'in'],
|
||
'string': ['in', 'not_in', '=='],
|
||
}
|
||
|
||
def validate(group):
|
||
for member in group.members:
|
||
v = member.value
|
||
assert v.op in ALLOWED_OPS[v.type], \
|
||
f'Op {v.op} not allowed for type {v.type}'
|
||
assert isinstance(v.value, (int, float, list, str)) if v.op != 'in' else isinstance(v.values, list)
|
||
# 比较运算符不允许字符串值
|
||
if v.op in ['<=', '>=', '<', '>'] and v.type == 'ratio':
|
||
assert 0 <= v.value <= 1, f'ratio out of [0,1]: {v.value}'
|
||
```
|
||
|
||
### 3.4 运行时执行
|
||
|
||
```python
|
||
# brain/policy/semantic_match.py
|
||
def match(action, member):
|
||
actual = action.params[member.param]
|
||
v = member.value
|
||
|
||
if v.type == 'ratio':
|
||
# 转换为绝对比例 (相对于 capability range)
|
||
cap_range = registry[action.device].capabilities[member.param].range
|
||
actual_ratio = (actual - cap_range[0]) / (cap_range[1] - cap_range[0])
|
||
|
||
if v.op == '<=': return actual_ratio <= v.value
|
||
if v.op == '>=': return actual_ratio >= v.value
|
||
...
|
||
elif v.type == 'enum':
|
||
if v.op == 'in': return actual in v.values
|
||
if v.op == 'not_in': return actual not in v.values
|
||
...
|
||
```
|
||
|
||
绕过尝试: speed = 10.0001% → actual_ratio = 0.10001 > 0.10 → 不匹配 production_halt → **正确不升格**, 但若组合中其他维度命中, 仍可能触发其他 group 升格 (这是设计意图)。
|
||

|
||
|
||
## 4. 分级签名链 (P0-4)
|
||
|
||
### 4.1 三档客群
|
||
|
||
| 客群 | 签名等级 | 流程 |
|
||
|---|---|---|
|
||
| **轻量** (中小工厂 < 30 设备, 非合规敏感) | 单签 + 在线 TPM | IT 主管 SSH 触发 + TPM 自动签 |
|
||
| **标准** (中型工厂 30-100 设备, 等保二级) | 双签 + 在线 HSM | 设备部主管 + IT 主管 双 SSO + YubiHSM |
|
||
| **高合规** (大型/军工/制药 GMP/CIIA) | M-of-N (2/3) 离线 HSM | Air-Gap 签名机 + 多人到场 |
|
||
|
||
### 4.2 部署形态自描述
|
||
|
||
```yaml
|
||
# deployment-profile.yaml (受 ops-key 签名)
|
||
profile: standard # lightweight | standard | high_compliance
|
||
|
||
signing:
|
||
ops_key:
|
||
storage: ${profile == 'high_compliance' ? 'air_gap_hsm' : 'online_hsm'}
|
||
threshold: ${profile == 'high_compliance' ? '2-of-3' : profile == 'standard' ? '2-of-2' : '1-of-1'}
|
||
rotation_days: ${profile == 'high_compliance' ? 365 : 180}
|
||
|
||
reviewer_idp:
|
||
require_different: ${profile != 'lightweight'}
|
||
require_different_dept: ${profile == 'high_compliance'}
|
||
|
||
dry_run:
|
||
isolation: ${profile == 'high_compliance' ? 'mirror_plc_cluster' : 'simulator'}
|
||
|
||
audit:
|
||
merkle_chain: true # 三档全部启用
|
||
rfc3161_anchor: ${profile != 'lightweight'}
|
||
worm_storage: ${profile == 'high_compliance'}
|
||
retention_days: ${profile == 'high_compliance' ? 1825 : 180} # 5y vs 6m
|
||
```
|
||
|
||
### 4.3 升级路径
|
||
|
||
客户从轻量起步 → 标准 → 高合规, 每档迁移由迁移工具自动完成 (密钥重签 + 历史日志重哈希入新链)。
|
||

|
||
## 5. v1.1 残留 5 项收口 (P0-5 至 P0-9)
|
||
|
||
### 5.1 ADB over WiFi 全文禁用 (P0-5)
|
||
|
||
```
|
||
v1.3 Android 接入仅以下三种模式, ADB-over-WiFi 5555 端口在工控/工厂场景**完全禁用**:
|
||
|
||
✅ 模式 A: ADB over USB (有线, 仅工程师调试用)
|
||
✅ 模式 B: Termux + SSH + 证书 (推荐, 7×24 后台 Agent)
|
||
✅ 模式 C: Scrcpy + Vision (受限设备视觉兜底)
|
||
❌ 模式 D: ADB over WiFi 5555 (禁用)
|
||
|
||
强制规则:
|
||
- Edge Gateway DPI 自动阻断 5555/tcp 出站连接
|
||
- 设备注册表对 type=android 的设备校验 protocol ∈ {adb_usb, termux_ssh, scrcpy_vision}
|
||
- CI 静态扫描 MCP 配置, 出现 :5555 直接 FAIL
|
||
```
|
||
|
||
### 5.2 Registry 引用图 DAG 校验 (P0-6)
|
||
|
||
```python
|
||
# tools/registry-dag-check.py
|
||
def validate_no_cycles(registry):
|
||
"""via_gateway 引用必须形成 DAG, 不允许环"""
|
||
graph = {d.id: d.via_gateway for d in registry.devices if d.via_gateway}
|
||
|
||
# Kahn 算法或 DFS 三色法
|
||
color = {} # white / gray / black
|
||
|
||
def visit(node):
|
||
if node not in graph: return
|
||
if color.get(node) == 'gray':
|
||
raise CycleDetected(f'{node} is part of a cycle')
|
||
if color.get(node) == 'black':
|
||
return
|
||
color[node] = 'gray'
|
||
visit(graph[node])
|
||
color[node] = 'black'
|
||
|
||
for d in registry.devices:
|
||
visit(d.id)
|
||
|
||
# 同时校验深度上限 (防过深嵌套)
|
||
MAX_DEPTH = 5
|
||
for d in registry.devices:
|
||
depth = compute_depth(d, graph)
|
||
if depth > MAX_DEPTH:
|
||
raise DepthExceeded(f'{d.id} via_gateway depth = {depth}')
|
||
```
|
||
|
||
CI 必跑, 失败阻 merge。
|
||
|
||
### 5.3 HARD_ACTION 预算双轨 (P0-7)
|
||
|
||
```yaml
|
||
# llm-providers.yaml (扩展 cost_control)
|
||
cost_control:
|
||
# 主预算 (业务读写)
|
||
main_budget:
|
||
daily_usd: 50
|
||
on_exhausted: route_to_local_only # 不 fail-closed, 降级本地
|
||
|
||
# HARD_ACTION 独立预算 (永不为 0)
|
||
safety_budget:
|
||
daily_usd: 10
|
||
reserved: true # 不与 main_budget 共用
|
||
on_exhausted:
|
||
- route_to_local_qwen3 # 走本地大模型
|
||
- if_local_unavailable: page_oncall_engineer # 失败转人工
|
||
# 永不 deny HARD_ACTION 评估
|
||
|
||
# 紧急超额池 (一次性, 季度复审)
|
||
emergency_pool:
|
||
quarterly_usd: 50
|
||
requires_approval: csso # CSO 审批激活
|
||
```
|
||
|
||
**关键**: HARD_ACTION 评估**永远不能因预算耗尽而拒绝**, 否则成为新的攻击面 (攻击者通过批量 SOFT_PARAM 耗尽预算, 让 HARD_ACTION 阻塞→生产中断)。
|
||
|
||
### 5.4 LLM Adapter Schema 归一矩阵 (P0-8)
|
||
|
||
各厂商 tool_call JSON 格式差异:
|
||
|
||
```python
|
||
# llm/adapters/normalizer.py
|
||
|
||
NORMALIZED_TOOL_CALL = {
|
||
'id': str,
|
||
'name': str,
|
||
'arguments': dict, # 必须是 dict, 不是 JSON string
|
||
}
|
||
|
||
class QwenAdapter:
|
||
def normalize_tool_call(self, raw):
|
||
# Qwen: arguments 是 string (JSON encoded)
|
||
return {
|
||
'id': raw['id'],
|

### 5.5 数据二极管 vs 防火墙明确 (P0-9)
|
||
|
||
```
|
||
| 部署档位 | L3-L1 边界实现 |
|
||
|---|---|
|
||
| 轻量 | 严格防火墙 (iptables 状态化, 仅允许 Gateway IP 白名单) |
|
||
| 标准 | 严格防火墙 + DPI (bump-in-wire) + 单向心跳监控 |
|
||
| 高合规 | **真正的硬件单向数据二极管** (Owl/Waterfall/国产: 鼎信 / 永信至诚) |
|
||
|
||
数据二极管硬件原理:
|
||
- 物理光纤单向 (无返回 fiber)
|
||
- 接收端无电信号到发送端的反向通路
|
||
- 写入操作通过专门的"反向通道"经人工/审批后转发, 大脑不直连
|
||
```
|
||
|
||
中小工厂部署轻量档, 不强求二极管硬件 (太贵 ¥20w+); 大客户部署高合规档强制使用。

## 6. 物理动作不可逆显式声明 (P0-10)
|
||
|
||
### 6.1 不可逆动作清单
|
||
|
||
```yaml
|
||
# irreversible-actions.yaml (受 ops-key 签名)
|
||
irreversible_actions:
|
||
- capability_pattern: "agv.*move"
|
||
reason: AGV 已搬运的货架, 搬回是新动作非补偿, 中途状态不一致
|
||
saga_compensation: forward_only_with_human_review
|
||
|
||
- capability_pattern: "robot_arm.*linear_move|joint_move"
|
||
reason: 机器人臂位置已改变, 反向运动需重新规划路径
|
||
saga_compensation: forward_only_with_human_review
|
||
|
||
- capability_pattern: "valve.set_state"
|
||
reason: 阀门切换涉及流体动力, 反向切换需考虑系统压力
|
||
saga_compensation: gradual_reverse_only
|
||
|
||
- capability_pattern: "heater.set_setpoint"
|
||
reason: 温度变化有惯性, 补偿动作不等价回滚
|
||
saga_compensation: best_effort_only
|
||
|
||
- capability_pattern: ".*write.*" # 所有写入默认不可逆
|
||
reason: 物理世界副作用不可撤销
|
||
saga_compensation: forward_only_with_human_review
|
||
```
|
||
|
||
### 6.2 Saga 补偿语义升级
|
||
|
||
```python
|
||
# brain/saga/compensation.py
|
||
|
||
class SagaStep:
|
||
def execute(self):
|
||
if self.is_irreversible():
|
||
# 不可逆动作禁止并行 (单设备单事务)
|
||
self.acquire_exclusive_lock(self.device_id)
|
||
|
||
# 执行前必须 dual-confirm (HARD_ACTION 已要求, SOFT_PARAM 此处也要求)
|
||
if not self.has_pre_confirm():
|
||
raise PreConfirmRequired()
|
||
|
||
result = self._do_execute()
|
||
return result
|
||
|
||
def compensate(self):
|
||
if self.is_irreversible():
|
||
# 不能自动补偿, 必须人工到场
|
||
return CompensationResult(
|
||
status='REQUIRES_HUMAN',
|
||
hint='物理动作已发生且不可逆, 请操作员现场评估补救',
|
||
suggested_actions=self.suggest_forward_recovery()
|
||
)
|
||
else:
|
||
return self._do_compensate()
|
||
```
|
||
|
||
### 6.3 文档警示
|
||
|
||
每个 capability 在 Registry 中显式标注:
|
||
|
||
```yaml
|
||
- id: agv_move_to_station
|
||
type: write
|
||
safety_level: SOFT_PARAM
|
||
irreversible: true # 显式标注
|
||
irreversible_warning: |
|
||
AGV 移动后, 货架物理位置已变. 撤销操作 = 派 AGV 反向搬运,
|
||
属于新任务, 不是补偿. 中间过程产线可能因货架不在位停产.
|
||
```
|
||
|
||
UI/CLI 在用户确认前必须显示此警告。

## 7. boot_id epoch 化 (P1-1)
|
||
|
||
### 7.1 v1.2 漏洞回顾
|
||
|
||
LRU(100) 满后旧 boot_id 被淘汰, 攻击者诱导 MCU 重启 101 次后回放首个 boot_id。
|
||
|
||
### 7.2 v1.3 修订
|
||
|
||
```c
|
||
// MCU 固件 (STM32 / ATECC608)
|
||
|
||
#define EPOCH_FLASH_ADDR 0x0801F000 // 专用 flash sector
|
||
#define EPOCH_MAGIC 0xBEEF1234
|
||
|
||
typedef struct {
|
||
uint32_t magic;
|
||
uint64_t boot_epoch; // 单调递增, 每次启动 +1, flash 持久化
|
||
uint32_t crc;
|
||
} boot_persist_t;
|
||
|
||
uint64_t get_or_init_boot_epoch() {
|
||
boot_persist_t persist;
|
||
flash_read(EPOCH_FLASH_ADDR, &persist, sizeof(persist));
|
||
|
||
if (persist.magic != EPOCH_MAGIC || crc32(&persist) != persist.crc) {
|
||
// 首次启动或 flash 损坏
|
||
persist.magic = EPOCH_MAGIC;
|
||
persist.boot_epoch = 1;
|
||
} else {
|
||
persist.boot_epoch += 1;
|
||
}
|
||
persist.crc = crc32(&persist);
|
||
flash_write(EPOCH_FLASH_ADDR, &persist, sizeof(persist));
|
||
|
||
return persist.boot_epoch;
|
||
}
|
||
```
|
||
|
||
### 7.3 心跳协议升级
|
||
|
||
```
|
||
heartbeat_v3 = {
|
||
device_id,
|
||
boot_epoch, // 持久化单调, 不会重用
|
||
counter, // boot 内单调
|
||
timestamp_ms,
|
||
mac = HMAC(key, all_above || prev_mac)
|
||
}
|
||
|
||
Gateway 验证:
|
||
1. boot_epoch > last_seen_epoch[device_id] (单调, 不允许等于)
|
||
2. 同 epoch 内 counter 单调
|
||
3. flash 寿命: STM32 内置 flash ~10w 写次数 / 每次启动 1 次写 = 273 年, 远超设备生命周期
|
||
```
|
||
|
||
LRU 改为**永久持久化 last_seen_epoch[device_id]** 在 Gateway TPM 中, 容量按设备数 (50 设备 × 200 byte = 10KB), 不淘汰。

## 8. bump-in-wire 双冗余 + 远程证明 (P1-2)
|
||
|
||
### 8.1 双冗余架构
|
||
|
||
```
|
||
[Edge Gateway]
|
||
↓ (mTLS)
|
||
│
|
||
[VRRP 虚拟 IP] ← 唯一访问入口
|
||
│
|
||
┌───┴───┐
|
||
↓ ↓
|
||
[Bump A] [Bump B] ← 主备热切换
|
||
│ │
|
||
└───┬───┘
|
||
↓ (短网线)
|
||
[PLC]
|
||
```
|
||
|
||
主备 bump 互发心跳 (1Hz), 主失效 100ms 内自动切备。
|
||
|
||
### 8.2 远程证明 (TPM Attestation)
|
||
|
||
每台 bump 启动时:
|
||
|
||
```
|
||
1. TPM 测量 boot loader / kernel / rootfs / DPI 规则 → PCR registers
|
||
2. Edge Gateway 周期 (5min) 发起 quote 请求
|
||
3. Bump 用 TPM AIK 签 PCR 值 + nonce
|
||
4. Gateway 验证签名 + 比对预期 PCR
|
||
5. 不匹配 → 该 bump 隔离 + 切备 + 告警
|
||
```
|
||
|
||
### 8.3 fail-mode
|
||
|
||
| 场景 | 行为 |
|
||
|---|---|
|
||
| 主 bump 软件 hang | VRRP 切备, 业务无感 |
|
||
| 主 bump 硬件故障 | 同上, 维护窗口替换 |
|
||
| 双 bump 同时失效 | PLC 不可达, 大脑读取超时, 触发降级 |
|
||
| TPM attestation 失败 | 立即隔离 + Audit + 告警 ops |
|
||
| **DPI 规则未到达** | bump fail-closed: 拒绝所有流量直到规则同步 |
|
||
|
||
### 8.4 国产 ARM 工控机 secure boot
|
||
|
||
国产网关 (研华/研祥/华北工控) 多数无 OEM Secure Boot, v1.3 强制清单:
|
||
|
||
- BootROM 不可信 → 加装 LetsTrust TPM 模块外接验证 boot loader
|
||
- 或选用支持 ARM TrustZone + UEFI Secure Boot 的国产网关 (华为 Atlas / 飞腾派工业版)
|
||
- 高合规客户必须采购预审过的型号 (年度更新认证清单)

## 9. ISV Skill 沙箱 + 隔离 (P1-3)
|
||
|
||
### 9.1 ISV Skill 信任模型
|
||
|
||
```
|
||
[Bookworm 平台]
|
||
ops-key (平台核心 Skill)
|
||
[ISV 厂商]
|
||
isv-key-A, isv-key-B... (各 ISV 独立)
|
||
[客户端]
|
||
customer-key (客户最终批准)
|
||
```
|
||
|
||
ISV Skill 经 isv-key 签名后上架, **客户端启用前必须 customer-key 二次签名**。
|
||
|
||
### 9.2 沙箱执行
|
||
|
||
ISV Skill 在大脑内**隔离进程 + 资源限制**:
|
||
|
||
```yaml
|
||
# isv-skill-sandbox.yaml
|
||
sandbox:
|
||
isolation: subprocess # 不与大脑同进程
|
||
|
||
resource_limits:
|
||
cpu: 0.5 core
|
||
memory: 512 MB
|
||
network: deny_all_except_mcp # 只能调注册的 MCP, 不能 raw socket
|
||
filesystem: read_only_workspace
|
||
|
||
capability_whitelist:
|
||
# ISV Skill 只能调用 ops 预先批准的 MCP tools
|
||
allowed_mcp_tools:
|
||
- opcua-mcp.read_*
|
||
- modbus-mcp.read_*
|
||
# 显式不允许写入类
|
||
|
||
audit:
|
||
log_every_call: true
|
||
quarantine_on_anomaly: true
|
||
```
|
||
|
||
### 9.3 ISV Skill 审计
|
||
|
||
平台维护 ISV Skill 行为基线, 异常告警:
|
||
|
||
- 调用频率突变
|
||
- 调用 tool 模式偏离声明
|
||
- 资源使用激增 (CPU/MEM)
|
||
|
||
发现可疑立即 quarantine + 通知所有客户。
|
||
|
||
### 9.4 客户端最终控制
|
||
|
||
```yaml
|
||
# customer-isv-policy.yaml (客户本地, customer-key 签)
|
||
allowed_isv_skills:
|
||
- id: isv-acme-pump-monitor
|

## 10. Registry 周期重验证 (P1-4)
|
||
|
||
### 10.1 周期 capability handshake
|
||
|
||
大脑后台进程每 24 小时遍历所有 capability 重做协议反查:
|
||
|
||
```python
|
||
# brain/registry/periodic_validator.py
|
||
async def periodic_revalidate():
|
||
while True:
|
||
for cap in registry.all_capabilities():
|

try:
|
||
actual = await mcp_client.introspect(cap.address, cap.protocol)
|
||
|
||
# 检测漂移
|
||
if actual.access_level != cap.declared_access:
|
||
cap.mark_degraded(reason='access_level_drift')
|
||
audit.log('REGISTRY_DRIFT', cap, actual)
|
||
|
||
if actual.datatype != cap.datatype:
|
||
cap.mark_degraded(reason='datatype_drift')
|
||
|
||
cap.last_verified_ts = HybridClock.wall_now_ms()
|
||
|

except CapabilityVerificationError as e:
|
||
cap.mark_unreachable(reason=str(e))
|
||
|
||
await asyncio.sleep(24 * 3600)
|
||
```
|
||
|
||
### 10.2 漂移分级响应
|
||
|
||
| 漂移类型 | 响应 |
|
||
|---|---|
|
||
| access_level: read → read+write | DEGRADE, 写入禁用直到人工确认 |
|
||
| datatype 变化 | DEGRADE + 拒绝该 capability 直到 PR 更新 Registry |
|
||
| 节点不存在 | UNREACHABLE, 24h 内未恢复降为 archived |
|
||
| safety_level 隐式提升 (协议反查发现该地址被改为 HARD 类) | CRITICAL ALERT + 立即拒绝, 通知 csso |
|
||
|

### 14.1 Margin Gate 公式重写
|
||
|
||
```python
|
||
# v1.2 错误: baseline = max(0.10, p95-p5) ← 极差不是判别阈值

## 18. 终极判定
|
||
|
||
**v1.3 自评 84-86 (B+)**, 经独立第三方红队 + 算法 + 市场 + CTO 复审通过 ≥85 后:
|
||
|
||
- ✅ 启动 Phase 0 PoC (60 人日, 8 周)
|
||
- ✅ Phase 1 生产基础平台 (160 人日, 3 月)
|
||
- ✅ Phase 2 工业接入 (280 人日, 6 月)
|
||
|
||
任何 v1.3 后续修订需经"演进日志"独立文档记录, 并按变更影响等级触发不同级别的复审 (minor: 单专家 / major: 四专家全审)。
|
||

|
||
|
||
> **v1.3 承诺**: 不再加新机制, 把 v1.0/v1.1/v1.2 累积的 22 项漏洞全部收口。
|
||
> 评分目标 B+ (≥85) 达成后即可正式启动工程实施。
