ABSTRACT:
The present invention provides an apparatus for securely acquire a circuit configuration information set corresponding to a new cryptosystem without increasing the number of reconfigurable circuits. A content playback apparatus100includes an FPGA122that is reconfigurable. The content playback apparatus100stores a decryption circuit program that shows the structure of a decryption circuit that executes decryption in accordance with a prescribed cryptosystem. The FPGA is reconfigured in accordance with the program to configure the decryption circuit. The playback apparatus100acquires, from outside, an encrypted file that has been generated by encrypting a file including a decryption circuit program corresponding to the new cryptosystem in accordance with the prescribed cryptosystem, and decrypts the encrypted file by the decryption circuit.
