ABSTRACT:
A system and method for generating, storing and retrieving cryptographic keys to be utilized in a processor-based system. In one embodiment, a Touch Memory ("TM") containing unique information is used as a portable memory to interface with a processor-based system wherein a cryptographic key generation program utilizes the unique information in the generation of cryptographic key sets. The generated encryption and decryption keys are stored on at least one such portable memory. Additionally, the encryption key is stored in the processor-based system. The presence of at least one specific portable memory is necessary at the time of decryption of data encrypted utilizing an encryption key associated with a decryption key, or portion thereof, stored on the specific portable memory.
