Abstract: A computer system (20) having a security domain (22), at least one client business domain (26), and a plurality of client terminals (34) utilizes a hidden link dynamic key manager (24, 84) and a database structure that includes encrypted data entities (30C, 30D) and a security identification attribute (32) for storage of encrypted data. Methods for encrypting data and for storing, decrypting, and retrieving encrypted data operate on the computer system (20), which also includes an information database (62) and a key database (44). The key database (44) is isolated from the information database (62). The hidden link key manager is stored in the security domain (22) and includes a system key manager (84) operable to generate system keys with system key common names and an encryption key manager (24) operable to generate encryption keys having encryption key identifications. The key managers (24, 84) operate on a key server (40), which is mirrored by a secondary key server (42).
