Secure Execution Processor

Geon Secure Execution Processor delivers secure code execution by supporting two secure contexts.

Overview

Geon Secure Execution Processor delivers secure code execution by supporting two secure contexts. All code and data belonging to a secure context is cryptographically isolated in main memory, so even complete software breach outside of secure context doen not compromise its security (confidentiality or integrity).

Cryptographic operations can be performed with single Keccak (SHA3) core or by combination of cryptographic hash primitives (SHA3 or SHA2) and symmetric ciphers.

Despite upgrades allowing for secure execution processing, the Geon processor maintains high configurability, performance and efficiency of the proven BA22. Performance is remaining in-line with BA22-CE.

The processor is already verified at system level and suitable for diverse security needs.
