20090034735	AUDITING SECRET KEY CRYPTOGRAPHIC OPERATIONS - In a cryptographic system, the unlocking of secret keys on a user system is audited and correlated with other events that typically occur after the secret key is used to perform a cryptographic operation. Audit evidence of secret key cryptographic operations is recorded for later review and/or analysis, for use as stored evidence of unauthorized activity and/or for use in refuting false claims of repudiation of authorized activity. Some systems might also provide users with user activity reports that can alert a user to suspicious or unauthorized activity using that user's access.	02-05-2009

20100172504	METHOD AND APPARATUS FOR CRYPTOGRAPHIC KEY STORAGE WHEREIN KEY SERVERS ARE AUTHENTICATED BY POSSESSION AND SECURE DISTRIBUTION OF STORED KEYS - A key management system includes secured data stored on a first system secured by a control key stored securely on a key server. The secured data is secured against attacks such as unauthorized use, modification or access, where authorization to access the secured data is determined by knowledge of an access private key of an access key pair. When an authorized user is to access the secured data, the first system generates a request to the key server, signed with the access private key, wherein the request is for a decryption control key and the request includes a one-time public key of a key pair generated by the first system for the request. The first system can decrypt the decryption control key from the response, using a one-time private key. The first system can then decrypt the secured data with the decryption control key remaining secured in transport.	07-08-2010
