PROBLEM TO BE SOLVED: To provide a terminal capable of reducing server's processing load and decrypting data encrypted by the server in a state disconnected from the server, and a program to be applied to the terminal. SOLUTION: The terminal 100 for acquiring data stored in the server 200 from the server 200 is provided with a communication part 101 for transmitting key generation information to be used for the generation of an encryption key for encrypting data to the server 200 and acquiring data encrypted by the server 200 by using the encryption key generated on the basis of the key generation information from the server 200, and a decryption processing part 109 for decrypting the data encrypted by the server 200 by using a decryption key generated on the basis of the key generation information. The key generation information includes at least a state ID to be updated when the terminal 100 is reconnected to the server 200. COPYRIGHT: (C)2007,JPO&INPIT
