Module security 

Security features for GPU kernel protection and compliance.

This module provides enterprise-grade security features:

• Memory Encryption: Encrypt sensitive GPU memory regions
• Kernel Sandboxing: Isolate kernels with resource limits and access controls
• Compliance Reports: Generate audit-ready compliance documentation

Memory Encryption

use ringkernel_core::security::{MemoryEncryption, EncryptionConfig, EncryptionAlgorithm};

let config = EncryptionConfig::new()
    .with_algorithm(EncryptionAlgorithm::Aes256Gcm)
    .with_key_rotation_interval(Duration::from_secs(3600));

let encryption = MemoryEncryption::new(config)?;
let encrypted = encryption.encrypt_region(&sensitive_data)?;
let decrypted = encryption.decrypt_region(&encrypted)?;

Kernel Sandboxing

use ringkernel_core::security::{KernelSandbox, SandboxPolicy, ResourceLimits};

let policy = SandboxPolicy::new()
    .with_memory_limit(1024 * 1024 * 1024)  // 1GB
    .with_execution_timeout(Duration::from_secs(30))
    .deny_k2k_to(&["untrusted_kernel"]);

let sandbox = KernelSandbox::new(policy);
sandbox.apply_to_kernel(&kernel_handle)?;

Compliance Reports

use ringkernel_core::security::{ComplianceReporter, ComplianceStandard, ReportFormat};

let reporter = ComplianceReporter::new()
    .with_standard(ComplianceStandard::SOC2)
    .with_standard(ComplianceStandard::GDPR);

let report = reporter.generate_report(ReportFormat::Pdf)?;
