ABSTRACT:
A secure memory device which can be used for multi-application smart cards for secure identification in data transfer, or for component verification in a computer system, without the requirement of an internal microprocessor. The secure memory device features a dual authentication protocol in which the memory and host authenticate each other. The secure memory device also includes an encrypted password feature, as well as using stream encryption to encrypt the data.
