  • Method and system for providing cryptographic services in a distributed application
    Patent number: 6754819
    Abstract: A data security system (26) provides cryptographic services in a multiprocessor platform (20) supporting a distributed application (22). The distributed application (22) includes a cryptographic object (52) that is executable exclusively on the data security system (26). An input interface object (102), a cryptographic function (90), and an output interface objection (104) form the cryptographic object (52). The data security system (26) includes a first processor element (92) for executing the input interface object (102), a second processor element (94) for executing the cryptographic function (90), and a third processor element (96) for executing the output interface object (104). The combination of data security system (26) and cryptographic object (52) ensures the separation of plain text data (46) from cipher text data (48).
