Sibros Virtual Security Modules (VSMs) bring HSM-class protection to devices and vehicles that lack dedicated secure hardware. By isolating keys and cryptographic operations in a hardened software enclave, VSMs let OEMs and IoT manufacturers enforce secure boot, firmware integrity, and encrypted communications without redesigning hardware.
Built on the same safety-critical principles as physical HSMs, VSMs integrate natively with Sibros’ connected platform for key provisioning, update signing, and lifecycle management.

Key Capabilities
Secure Key Storage & Management
Protect asymmetric and symmetric keys in a tamper-resistant software enclave, with role-based access and rotation policies.
Cryptographic Services API
Expose standard crypto functions (sign, verify, encrypt, decrypt, hash) to applications and update agents without exposing raw keys.
Secure Boot & Firmware Validation
Verify bootloaders, kernels, and application images before execution; enforce chain of trust from manufacturing to field updates.
OTA Update Integrity & Signing
Integrates with Sibros OTA & Lifecycle Management to verify update packages, ensuring authenticity and preventing rollback or tampering.
Certificate Lifecycle Integration
Pairs seamlessly with Sibros Certificate Authority to issue, renew, revoke, and rotate certificates without manual intervention.
Isolation & Anti-Tamper Protections
Leverages memory isolation, secure containers, and anti-debugging to make extraction or tampering highly difficult even on compromised hosts.
Flexible Deployment
Available for Linux, POSIX, and RTOS environments - ideal for TCUs, gateways, and controllers without built-in HSM chips.
Why It Matters
Why It Matters
Bridge the Hardware Gap
Add strong cryptography and secure key storage when physical HSMs aren’t present or feasible.
Accelerate Compliance
Meet cybersecurity and OTA regulations (e.g., UNECE WP.29, EU CRA) without redesigning electronics.
Future-Proof Security
Easily update crypto algorithms, rotate keys, and patch vulnerabilities via OTA.
Unified with Sibros Platform
Manage keys, certificates, and update integrity alongside your existing Sibros connected stack.
