ABSTRACT:
A semiconductor device used to store 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 (i) a non-volatile memory capable of storing the encryption/decryption keys and at least one digital certificate, (ii) an internal memory capable of temporarily storing information input into the semiconductor device from the other device and possibly encryption and decryption algorithms, (iii) a processor for processing the information and (iv) a random number generator for generating the encryption/decryption keys completely internal to the semiconductor device.
