摘要： An IC chip, a board, information processing equipment, and a storage medium are provided that can prevent, even when information is transferred between a plurality of programs, leaking of the right protection algorithm of information in connection with the transfer. A security board is included an IC chip having a secure module. The secure module receives an encryption key request signal, and generates a communication encryption key every time when the encryption key request signal is received, the communication encryption key being used to encrypt information to be transferred between a plurality of programs. The number of times the communication encryption key is supplied is counted. If the counted number is equal to or less than a predetermined number, the communication encryption key is supplied to outside. If the counted number exceeds the predetermined number, the supply of the generated communication encryption key to outside is stopped.
