Abstract:
1. A secure card adapter comprising: a card body which incorporates a microprocessor device, a read only memory device and a secure linear feedback shift register, the microprocessor device being interfaced to the read only memory device containing a pre-initialized personality configuration, said pre-initialized personality configuration being comprised of both a unique card identification and a customized secure linear feedback shift register initial configuration; a reference linear feedback shift register incorporated in said card body and synchronized to the secure linear feedback shift register; a security code generator incorporated in said card body and producing a security code utilizing said secure linear feedback shift register, said secure linear feedback shift register being driven by a common free-running clock oscillator and providing outputs which, when combined with the card identification, produce a security code uniquely based upon said pre-initialized personality configuration, said security code being accessible by the microprocessor; a communication interface incorporated in said card body and connected to said microprocessor device, said communication device providing an input/output message function of the secured information between the microprocessor and an agent outside said secure card body; and means for writing unique transaction information on a machine-readable medium on a card structure.
