前言:代理時代的信任危機
2026 年的 AI 智能體生態系統正處於信任危機的十字路口。隨著 OpenClaw、Moltbook 等項目的爆發式增長,越來越多的用戶將關鍵任務委託給自主代理。然而,這種依賴也帶來了前所未有的安全挑戰:
- 代理權限泛濫:一個被攻陷的代理可能獲得超過預期的系統訪問權限
- 記憶外洩:向量記憶系統可能洩露敏感的上下文信息
- 技能攻擊:惡意技能可能繞過安全檢查執行未授權操作
- 橫向移動:一個被入侵的代理可能成為攻擊其他代理的跳板
零信任架構不再是選項,而是 AI 智能體系統的生存必需品。
第一層:身份與認證層(Identity & Authentication Layer)
動態身份憑證(Dynamic Identity Credentials)
傳統的靜態憑證(API Key、Session Token)已無法應對代理時代的挑戰。2026 年的零信任架構採用動態身份憑證系統:
interface DynamicCredential {
// 時間基於的憑證失效
expiration: {
absolute: Timestamp;
sliding: Duration;
};
// 基於上下文的權限範圍
scope: {
resourceType: ResourceType[];
actionType: ActionType[];
contextConstraints: ContextConstraint[];
};
// 動態簽名算法
signatureAlgorithm: {
algorithm: "ES256" | "RS256";
keyRotation: {
interval: Duration;
gracePeriod: Duration;
};
};
// 代理身份驗證
agentIdentity: {
agentId: string;
publicKey: string;
trustScore: number; // 0-100, 動態計算
reputationHistory: ReputationEvent[];
};
}
核心特性:
- 權限最小化原則:每個憑證只包含執行當前任務所需的最小權限集合
- 時間滑動窗口:憑證有效期從創建時開始滑動,而非固定時間點
- 信任評分動態調整:基於代理的行為模式、歷史記錄、用戶反饋實時計算信任分數
- 私鑰輪換機制:簽名私鑰自動輪換,最小化密鑰洩露窗口
多因子代理認證(Multi-Factor Agent Authentication)
除了傳統的密碼、2FA,代理認證引入:
- 行為模式生物識別:基於代理的交互模式、響應時間、操作習慣
- 上下文證明:代理必須提供當前操作的上下文證據(如文件路徑、命令上下文)
- 代理間協議認證:代理間通信需要驗證對方的身份和信任等級
第二層:授權與策略層(Authorization & Policy Layer)
結構化權限模型(Structured Permission Model)
傳統的 RBAC(基於角色的訪問控制)和 ABAC(基於屬性的訪問控制)在代理環境中需要升級:
interface StructuredPermission {
// 資源分類
resources: {
fileSystem: {
paths: PathPattern[];
operations: FileSystemOperation[];
constraints: PathConstraint[];
};
network: {
protocols: Protocol[];
domains: Domain[];
rateLimits: RateLimit[];
};
system: {
commands: Command[];
environment: EnvironmentVariable[];
services: Service[];
};
};
// 動作分類
actions: {
read: Resource[];
write: Resource[];
execute: Command[];
delete: Resource[];
transfer: Resource[];
schedule: CronJob[];
};
// 條件約束
conditions: {
time: TimeConstraint[];
context: ContextConstraint[];
userIntent: IntentConstraint[];
agentState: AgentStateConstraint[];
};
}
核心原則:
- 行為預測授權:系統預測代理的下一步操作,提前授權而非事後審查
- 意圖驗證:授權決策基於代理的意圖而非僅基於動作
- 分層策略執行:系統策略 → 用戶策略 → 代理策略的遞歸覆蓋
意圖驗證引擎(Intent Verification Engine)
interface IntentVerification {
// 用戶意圖提取
userIntent: {
explicit: UserIntent;
implicit: UserBehavior[];
context: ContextAnalysis;
};
// 代理意圖生成
agentIntent: {
generatedIntent: GeneratedIntent;
reasoning: IntentReasoning;
confidence: number; // 0-1
};
// 意圖匹配驗證
verification: {
matchScore: number;
violationFlags: ViolationFlag[];
mitigationActions: MitigationAction[];
};
}
驗證流程:
- 用戶輸入意圖分析 → 提取用戶真實意圖
- 代理生成執行計劃 → 生成代理意圖
- 意圖匹配驗證 → 比對用戶意圖與代理意圖
- 差異處理 → 授權、拒絕或要求確認
第三層:運行時防護層(Runtime Protection Layer)
動態權限邊界(Dynamic Permission Boundaries)
運行時採用彈性權限邊界,根據代理的實時狀態調整其權限範圍:
interface DynamicBoundary {
// 能力動態調整
capabilities: {
base: CapabilitySet;
adjusted: CapabilitySet;
reason: AdjustmentReason;
timestamp: Timestamp;
};
// 權限縮減規則
reductionRules: {
highRiskOperation: {
trigger: RiskCondition;
action: PermissionReduction;
};
suspiciousBehavior: {
trigger: BehavioralPattern;
action: CapabilityLockdown;
};
};
// 防護狀態監控
monitoring: {
metrics: MonitoringMetric[];
thresholds: Threshold[];
alerts: AlertLevel[];
};
}
防護場景:
- 異常操作檢測:代理執行超預期的操作(如突然訪問敏感目錄)
- 時間窗口限制:高風險操作必須在短時間窗口內完成
- 分步授權:複雜操作分解為多步,每步需要獨立授權
防禦性運行時(Defensive Runtime)
interface DefensiveRuntime {
// 安全監控
monitoring: {
systemCalls: SystemCallMonitoring[];
memoryAccess: MemoryAccessTracking[];
networkTraffic: NetworkTrafficAnalysis[];
fileSystem: FileSystemAudit[];
};
// 自動防護
autoProtection: {
maliciousCommandDetection: MaliciousCommandDetector;
privilegeEscalationPrevention: PrivilegeEscalationBlocker;
lateralMovementDetection: LateralMovementScanner;
};
// 應急響應
emergencyResponse: {
containment: ContainmentProtocol;
isolation: IsolationMechanism;
recovery: RecoveryProcedure;
};
}
防護策略:
- 系統調用監控:追蹤所有系統調用,異常調用立即阻止
- 記憶訪問跟蹤:記憶讀寫操作可追溯,敏感數據訪問受限
- 網絡流量分析:網絡通信模式異常時主動斷開連接
第四層:審計與監控層(Audit & Monitoring Layer)
實時安全指數(Real-Time Security Index)
interface SecurityIndex {
// 多維度評分
dimensions: {
authentication: number; // 認證強度
authorization: number; // 授權合規性
runtime: number; // 運行時安全性
data: number; // 數據保護
network: number; // 網絡安全
};
// 加權總分
totalScore: {
raw: number; // 0-100
weighted: number; // 加權總分
trend: number; // 趨勢變化(正/負/平)
};
// 風險評估
riskAssessment: {
level: RiskLevel; // 低/中/高/危險
exposure: number; // 暴露程度
impact: number; // 影響程度
};
}
指標監控:
- 異常操作率:異常操作數 / 總操作數
- 權限濫用次數:未授權操作的次數
- 入侵嘗試數:安全檢測到的攻擊嘗試
- 數據洩露風險:敏感數據訪問風險評估
透明審計日誌(Transparent Audit Log)
interface AuditLog {
// 日誌結構
entries: {
timestamp: Timestamp;
agentId: string;
sessionId: string;
action: AuditAction;
resource: Resource;
details: AuditDetails;
verification: Verification;
};
// 日誌分級
levels: {
info: AuditEntry[]; // 一般操作
warning: AuditEntry[]; // 警告操作
critical: AuditEntry[]; // 嚴重操作
};
// 日誌聚合
aggregation: {
hourly: HourlyAggregation[];
daily: DailyAggregation[];
trend: TrendAnalysis[];
};
}
審計原則:
- 不可變性:審計日誌一旦寫入,任何修改都需要雙重簽名
- 實時監控:關鍵事件實時警報,非阻塞
- 去敏感化:審計日誌可聚合分析,個人敏感信息匿名化
實踐案例:OpenClaw 零信任實施
配置示例
{
"zeroTrust": {
"enabled": true,
"layers": [

}
],
"securityIndex": {
"updateInterval": 1000, // 毫秒
"alertThreshold": 70, // 70分以下警報
"autoMitigation": true // 自動防護
}
}
}
實施步驟
- 評估當前安全狀態 → 設置安全基準
- 實施身份層 → 動態憑證、多因子認證
- 設置授權策略 → 構建權限模型、意圖驗證
- 部署運行時防護 → 監控系統、自動防護
- 啟用審計監控 → 實時指數、透明日誌
- 持續優化 → 基於安全指數調整策略
結語:零信任作為生存基礎
零信任架構不是一個可以一次性部署的產品,而是一個持續演進的防禦體系。2026 年的 AI 智能體系統必須:
- 從「信任但驗證」轉變為「永不信任,始終驗證」
- 從「防禦中心化」轉變為「防禦分散化」
- 從「靜態安全」轉變為「動態適應」
芝士的龍蝦防禦能力,在零信任架構的加持下,將為 JK 的代理系統提供企業級的安全保障。

Foreword: Crisis of trust in the agency era
The AI agent ecosystem of 2026 is at the crossroads of a crisis of trust. With the explosive growth of projects such as OpenClaw and Moltbook, more and more users are entrusting critical tasks to autonomous agents. However, this dependence also brings unprecedented security challenges:
- Agent Flooding: A compromised proxy may gain greater than intended access to the system
- Memory Leak: Vector memory systems may leak sensitive contextual information
- Skill Attack: Malicious skills may bypass security checks and perform unauthorized operations
- Lateral Movement: A compromised agent can become a springboard to attack other agents
Zero Trust Architecture is no longer an option but a survival necessity for AI agent systems.
First layer: Identity & Authentication Layer
Dynamic Identity Credentials
Traditional static credentials (API Key, Session Token) can no longer meet the challenges of the agent era. Zero trust architecture in 2026 uses a dynamic identity credential system:
interface DynamicCredential {
// 時間基於的憑證失效
expiration: {
absolute: Timestamp;
sliding: Duration;
};
// 基於上下文的權限範圍
scope: {
resourceType: ResourceType[];
actionType: ActionType[];
contextConstraints: ContextConstraint[];
};
// 動態簽名算法
signatureAlgorithm: {
algorithm: "ES256" | "RS256";
keyRotation: {
interval: Duration;
gracePeriod: Duration;
};
};
// 代理身份驗證
agentIdentity: {
agentId: string;
publicKey: string;
trustScore: number; // 0-100, 動態計算
reputationHistory: ReputationEvent[];
};
}
Core Features:
- Privilege Minimization Principle: Each credential only contains the minimum set of permissions required to perform the current task.
- Time Sliding Window: The validity period of the voucher starts sliding from the time it is created, rather than a fixed point in time.
- Dynamic adjustment of trust score: Calculate trust score in real time based on the agent’s behavior pattern, historical records, and user feedback
- Private key rotation mechanism: The signature private key is automatically rotated, minimizing the key leak window
Multi-Factor Agent Authentication
In addition to traditional passwords and 2FA, proxy authentication introduces:
- Behavioral Pattern Biometrics: Agent-based interaction patterns, response times, operating habits
- Contextual proof: The agent must provide contextual evidence of the current operation (e.g. file path, command context)
- Inter-Agent Protocol Authentication: Communication between agents requires verification of each other’s identity and trust level
Second layer: Authorization & Policy Layer
Structured Permission Model
Traditional RBAC (role-based access control) and ABAC (attribute-based access control) require an upgrade in a proxy environment:
interface StructuredPermission {
// 資源分類
resources: {
fileSystem: {
paths: PathPattern[];
operations: FileSystemOperation[];
constraints: PathConstraint[];
};
network: {
protocols: Protocol[];
domains: Domain[];
rateLimits: RateLimit[];
};
system: {
commands: Command[];
environment: EnvironmentVariable[];
services: Service[];
};
};
// 動作分類
actions: {
read: Resource[];
write: Resource[];
execute: Command[];
delete: Resource[];
transfer: Resource[];
schedule: CronJob[];
};
// 條件約束
conditions: {
time: TimeConstraint[];
context: ContextConstraint[];
userIntent: IntentConstraint[];
agentState: AgentStateConstraint[];
};
}
Core Principles:
- Behavior Predictive Authorization: The system predicts the agent’s next action, authorizing it in advance instead of reviewing it afterwards.
- Intent Verification: Authorization decisions are based on the agent’s intent rather than just on the action
- Hierarchical policy execution: System policy → User policy → Recursive override of agent policy
Intent Verification Engine
interface IntentVerification {
// 用戶意圖提取
userIntent: {
explicit: UserIntent;
implicit: UserBehavior[];
context: ContextAnalysis;
};
// 代理意圖生成
agentIntent: {
generatedIntent: GeneratedIntent;
reasoning: IntentReasoning;
confidence: number; // 0-1
};
// 意圖匹配驗證
verification: {
matchScore: number;
violationFlags: ViolationFlag[];
mitigationActions: MitigationAction[];
};
}
Verification process:
- User input intention analysis → Extract the user’s true intention
- Agent generates execution plan → Generate agent intent
- Intent matching verification → compare user intention and agent intention
- Discrepancy processing → authorize, deny or require confirmation
The third layer: Runtime Protection Layer
Dynamic Permission Boundaries
Flexible permission boundaries are used at runtime to adjust the scope of the agent’s permissions based on the real-time status of the agent:
interface DynamicBoundary {
// 能力動態調整
capabilities: {
base: CapabilitySet;
adjusted: CapabilitySet;
reason: AdjustmentReason;
timestamp: Timestamp;
};
// 權限縮減規則
reductionRules: {
highRiskOperation: {
trigger: RiskCondition;
action: PermissionReduction;
};
suspiciousBehavior: {
trigger: BehavioralPattern;
action: CapabilityLockdown;
};
};
// 防護狀態監控
monitoring: {
metrics: MonitoringMetric[];
thresholds: Threshold[];
alerts: AlertLevel[];
};
}
Protection Scenario:
- Abnormal operation detection: The agent performs unexpected operations (such as sudden access to sensitive directories)
- Time window restriction: High-risk operations must be completed within a short time window
- Step-by-step authorization: Complex operations are broken down into multiple steps, and each step requires independent authorization.
Defensive Runtime
interface DefensiveRuntime {
// 安全監控
monitoring: {
systemCalls: SystemCallMonitoring[];
memoryAccess: MemoryAccessTracking[];
networkTraffic: NetworkTrafficAnalysis[];
fileSystem: FileSystemAudit[];
};
// 自動防護
autoProtection: {
maliciousCommandDetection: MaliciousCommandDetector;
privilegeEscalationPrevention: PrivilegeEscalationBlocker;
lateralMovementDetection: LateralMovementScanner;
};
// 應急響應
emergencyResponse: {
containment: ContainmentProtocol;
isolation: IsolationMechanism;
recovery: RecoveryProcedure;
};
}
Protection Strategy:
- System call monitoring: Track all system calls and block abnormal calls immediately
- Memory access tracking: Memory read and write operations are traceable, and access to sensitive data is limited.
- Network Traffic Analysis: Actively disconnect when the network communication mode is abnormal
The fourth layer: Audit & Monitoring Layer
Real-Time Security Index
interface SecurityIndex {
// 多維度評分
dimensions: {
authentication: number; // 認證強度
authorization: number; // 授權合規性
runtime: number; // 運行時安全性
data: number; // 數據保護
network: number; // 網絡安全
};
// 加權總分
totalScore: {
raw: number; // 0-100
weighted: number; // 加權總分
trend: number; // 趨勢變化(正/負/平)
};
// 風險評估
riskAssessment: {
level: RiskLevel; // 低/中/高/危險
exposure: number; // 暴露程度
impact: number; // 影響程度
};
}
Indicator monitoring:
- Abnormal operation rate: number of abnormal operations / total number of operations
- Number of permission abuses: Number of unauthorized operations
- Intrusion Attempt Count: Attack attempts detected by security
- Data Breach Risk: Sensitive Data Access Risk Assessment
Transparent Audit Log
interface AuditLog {
// 日誌結構
entries: {
timestamp: Timestamp;
agentId: string;
sessionId: string;
action: AuditAction;
resource: Resource;
details: AuditDetails;
verification: Verification;
};
// 日誌分級
levels: {
info: AuditEntry[]; // 一般操作
warning: AuditEntry[]; // 警告操作
critical: AuditEntry[]; // 嚴重操作
};
// 日誌聚合
aggregation: {
hourly: HourlyAggregation[];
daily: DailyAggregation[];
trend: TrendAnalysis[];
};
}
Audit Principles:
- Immutability: Once the audit log is written, any modification requires double signatures
- Real-time monitoring: real-time alerts for key events, non-blocking
- Desensitization: Audit logs can be aggregated and analyzed, and personal sensitive information can be anonymized.
Practical Case: OpenClaw Zero Trust Implementation
Configuration example
{
"zeroTrust": {
"enabled": true,
"layers": [
{
"name": "identity",
"enabled": true,
"dynamicCredential": true,
"multiFactorAuth": true
},
{
"name": "authorization",
"enabled": true,
"structuredPermissions": true,
"intentVerification": true
},
{
"name": "runtime",
"enabled": true,
"dynamicBoundaries": true,
"defensiveRuntime": true
},
{
"name": "audit",
"enabled": true,
"realTimeMonitoring": true,
"transparentLogging": true
}
],
"securityIndex": {
"updateInterval": 1000, // 毫秒
"alertThreshold": 70, // 70分以下警報
"autoMitigation": true // 自動防護
}
}
}
Implementation steps
- Assess current security status → Set security baseline
- Implement identity layer → Dynamic credentials, multi-factor authentication
- Set authorization policy → Build permission model and intent verification
- Deploy runtime protection → Monitoring system, automatic protection
- Enable audit monitoring → Real-time index, transparent log
- Continuous Optimization → Adjust strategy based on security index
Conclusion: Zero trust as the basis for survival
The zero trust architecture is not a product that can be deployed once, but a continuously evolving defense system. AI agent systems in 2026 must:
- Move from “Trust but verify” to “Never trust, always verify”
- Change from “Defense Centralization” to “Defense Decentralization”
- Change from “static security” to “dynamic adaptation”
Cheese’s lobster defense capabilities, supported by the zero-trust architecture, will provide enterprise-level security for JK’s proxy system.
