Module security 

Enterprise security for quantum cloud operations.

Provides structured audit logging, credential management, and token-bucket rate limiting for production quantum computing workloads, as well as a comprehensive Quantum System Security Framework.

Modules

• audit — Structured JSON audit log trail (file, in-memory, null sinks)
• credentials — Credential abstraction with env-var, file, and composite providers
• rate_limit — Per-provider token-bucket rate limiter
• config — Security configuration types for the full framework
• engines — Security engine and result types
• framework — Main QuantumSystemSecurityFramework implementation
• types — Security enums and shared types

Quick start

use quantrs2_device::security::{
    InMemoryAuditLogger, AuditLogger, AuditEvent, OperationType,
    EnvVarCredentialProvider, CredentialProvider,
    RateLimiter,
};

// Audit logging
let logger = InMemoryAuditLogger::new();
let event = AuditEvent::new(OperationType::CircuitSubmit, true)
    .with_backend("ibm_nairobi")
    .with_duration_ms(120);
logger.log(event).expect("audit log failed");

// Rate limiting
let mut limiter = RateLimiter::with_cloud_defaults();
if limiter.try_consume("ibm") {
    // proceed with API call
}
