DigiSAFE TrustCrypt – Secure Platform Module

The DigiSAFE TrustCrypt is a multi-chip embedded module designed to meet FIPS 140-2 level 3 security level.

TrustCrypt is a programmable cryptographic module designed to support high assurance applications and provide secure cryptographic resources, including secure key generation and storage. It is built upon a secure physical enclosure and contains a secure bootstrap which authenticates application loading.

The security services provided by TrustCrypt are AES, SHA, RSA and DRNG through the RS232 serial port.

Customized application can be downloaded into the TrustCrypt if needed. The customized application to be downloaded will be signed by approved authority using RSA.
