|20100095118||CRYPTOGRAPHIC KEY MANAGEMENT SYSTEM FACILITATING SECURE ACCESS OF DATA PORTIONS TO CORRESPONDING GROUPS OF USERS - Cryptographic Key Management System facilitating secure access of data portions to corresponding groups of users. In an embodiment, corresponding group key (asymmetric key pair) is provided for each group, with the private key being stored in a secure format requiring the user credentials for decryption. In addition, a data key required to decrypt a data portion of interest is encrypted using the group public key. Thus, when a user attempts to access a data portion, the user credentials are used to decrypt the group private key, which is then used to decrypt the data key. The data key is then used to decrypt the data portion of interest.||04-15-2010|
