Key management unit CK-guard

摘要

Management of private keys is a crucial issue in the sys- tems which require high-level security, such as certification authorities based on the RSA public key cryptosystem. NEC has developed a tamper resistant private key management equipment, CK-Guard. CK-Guard is accessed by a software of "Secureware/Private Key Module Manager" on the server connected with the CK-Guard. The users can manage CK- Guard through a generic API (Application Program Inter- face) provided in the software. This paper shows the func- tions and security concepts of CK-Guard.
