Overview

The Geon™ Secure Execution Processor is a low-power, 32-bit processor IP core with built-in protection of sensitive code and data. It uses two or more cryptographically separated execution contexts for a high degree of security during code execution and for data storage and transfer to and from the processor.

Geon benefits from the extreme code density of the BA2xTM ISA, and employs advanced power management to further lower CPU and memory subsystem power consumption. It can be licensed without volume-based royalty fees.

Key features

  • Built-in protection of code and data in a 32-bit compact, low-power, royalty-free, processor IP core.
  • Secure Execution
    • Protects sensitive code and data during execution, storage, and transfer to/from the processor
    • Uses two or more cryptographically isolated secure execution contexts
    • Agnostic to cryptographic primitives: 
      • uses lowest-overhead Keccak-based (SHA3) crypto engine by default; 
      • can alternatively support any cryptographic hash functions and symmetric cipher
  • Low-Power Operation
    • Extreme Code Density of the BA2x™ ISA minimizes instruction memory area and power consumption

Security in vehicular systems

With the advent of IoT and increasingly interconnected and autonomous nature of a vehicle’s control modules, there has been an exponential increase in V2V, V2X and inter vehicular communications. This in turn increases the attack surface for hackers which demands state-of-art security features in modern automotive microcontrollers, moreover safety and security go hand in hand.

A Comprehensive Post-Quantum Cryptography (PQC) Solution based on Physical Unclonable Function (PUF)

This article provides an in-depth analysis of the specific PPA challenges introduced by PQC and elucidates how PUF-PQC leverages its unique dualtrack strategy to deliver a robust and flexible Hardware Root of Trust (HRoT) across diverse application scenarios. Furthermore, it demonstrates the integration of Physical Unclonable Function (PUF) with a NIST SP 800-90B compliant True Random Number Generator (TRNG) to serve as critical components of PUFrt (Root of Trust), ensuring the security of post-quantum key generation starting from the entropy source.
