Security Stack Solution

Crypto Stack delivers a modular set of cryptographic services designed to secure embedded ECUs. The framework includes CSM, CryIf, KeyM, and software-based algorithm providers that ensure consistent, reliable execution across supported MCU platforms.

Built for secure boot, secure communication, authentication, and data protection workflows, the crypto stack supports industry-proven algorithms and integrates cleanly with the LeanStack architecture. It provides the foundation needed to safeguard system integrity and maintain trusted operation throughout the ECU lifecycle.

Secure your ECU with LeanStack Crypto Stack. From signature verification to encrypted communication, protect embedded systems with reliable and trusted cryptographic mechanisms.

Key Modules:

CSM (Crypto Service Manager): High-level cryptographic job handling for hashing, encryption/decryption, MAC generation, signature verification, and random number requests.

KeyM (Key Manager): Manages key generation, storage, derivation, and usage. Supports RSA and AES-based key handling for secure operations.

CryIf (Crypto Interface) Unified cryptographic abstraction layer that dispatches operations to software providers or hardware accelerators when available.

Supported Algorithms: RSA, AES and SHA-256 form the core of our cryptographic capabilities, enabling authentication, encryption, and integrity validation. Together, they ensure trusted operation and protect critical data across embedded systems.
