Abstract

A semiconductor device for storing encryption/decryption keys at manufacture in combination with digital certificates to ensure secured communications between the semiconductor device and another device. The semiconductor device comprising a non-volatile memory for storing the encryption/decryption keys and at least one digital certificate, internal memory for temporarily storing information input into the semiconductor device from the other device and possibly encryption and decryption algorithms, a processor for processing the information and a random number generator for generating the encryption/decryption keys completely internal to the hardware agent.
