Title:
Information processing system
Document Type and Number:
Japanese Patent JP6348273
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain an information processing system which can perform cryptographic communication using a session key while achieving reduction in packaging cost and improvement in attack resistance in the information processing system including a communication device and a storage device.SOLUTION: An information processing system comprises: a micro processor 11 which acquires an initial session key K0 in initialization processing before starting data communication by decrypting an encryption initial session key K0' received from a semiconductor storage device 3 in a second cryptographic algorithm to set the initial session key K0 to a key stream generation circuit; and the semiconductor storage device 3 which sets the initial session key K0 read from a memory array 23 to the key stream generation circuit.
