<P>PROBLEM TO BE SOLVED: To provide a wireless chip in which hardware structure thereof is not required to be modified each time encryption algorithm with higher security is developed. <P>SOLUTION: In a wireless chip, a circuit capable of communicating information by wireless communication, a CPU and a memory are included. In the memory, two or more regions, of each a region to which an encryption program is assigned and a region to which a decryption is assigned, are included. Accordingly, a wireless chip in which an encryption/decryption program can be rewritten without modifying the hardware structure can be provided. <P>COPYRIGHT: (C)2007,JPO&INPIT |
