Cryptographic key management and validating system

Abstract From the Canadian patent

A Key Management System for generating distributing, and managing cryptographic keys used by an information transaction system that employs cryptographic means to produce evidence of information integrity. The system comprises a plurality of functionally distinct secure boxes operatively coupled to each other. Each of the secure boxes performs functions for key generation key, installation, key verification or validation of tokens. Computers operatively coupled to the secure boxes provide system control and facilitate communication among the secure boxes. A plurality of separate logical security domains provide domain processes for key generation, key installation, key verification and …
