  • Patent number: 5623546
    Abstract: A system and method allows portable, encrypted data to be accessible through multiple hosts, including new hosts (14), without requiring a secure link to the new hosts. A split key encryption system encrypts (52) data and stores the encrypted data on a portable device (10). A split of the encryption key is stored (54) in the portable device (10), and another split of the key is stored (54) in a home host (12) . A password-modified key is then made (58) by combining a password with the encryption key. This password-modified key is then reduced (58), with one split being stored on the host (12) and another split stored on the portable device (10) . Data can be accessed with a new host (14) by transferring (78) the host password-modified split to the new host (14) and entering (80) the password into the portable device (10).

  • Patent number: 5103451
    Abstract: A method and circuitry for generating N-bit parallel CRC code from an N-bit parallel data input source. A generating polynomial function is used to express an array of exclusive-OR gates to which the N-bit parallel data inputs are applied. A plurality of N latches is provided and connected to the exclusive-OR gate array in a feedback fashion to provide the plurality of N-bit parallel CRC codes according to the polynomial function.
