Abstract: An information processing device having an activation verification function comprises: a module recording portion which stores plural system programs, a security chip having the function of checking the validity of the system programs and a verification portion which inspects the activation states of the system programs. The security chip executes validity checking processing using verification data provided by the system programs. If the security chip cannot confirm the validity of the system programs, the verification portion acquires activation-state information about activated system programs from the activated system programs. If pre-stored verification-information initial values for valid system programs and the acquired activation-state information match with each other, the verification portion determines that the current activation states of the system programs are valid, and the subsequent activation processing for the system programs is advanced.

Abstract: In an information access system, a reader/writer device encrypts, with a first encryption key, an information request and a second encryption key to thereby generate first encrypted data, and encrypts the information request with the second encryption key to thereby generate second encrypted data, and transmits cyclically an information request signal that alternately carries the first encrypted data and the second encrypted data. An active contactless information storage device receives the information request signal and decrypts the encrypted data carried by the information request signal with one encryption key stored in its memory. When the second encryption key different from the one encryption key is contained in the decrypted data, the information storage device rewrites the one encryption key with the second encryption key.
