    摘要: A random number sequence is previously generated by the function f8 for data confidentiality processing, which generates a random number sequence, and stored in a random number sequence memory (buffer). When data (message) is input, the random number sequence stored in the random number sequence memory is obtained, and the data (message) is encrypted by an XOR circuit to generate ciphertext data. In case of decrypting data, a random number sequence is also previously generated by the function f8 for data confidentiality processing and stored in the random number sequence memory (buffer). When the ciphertext data is input, by the XOR circuit, the random number sequence stored in the random number sequence memory is read and the ciphertext data is decrypted into the data (message).

    摘要: The present invention aims to downsize a configuration for achieving confidentiality of data on an air link of a mobile terminal and/or data for communication with a partner terminal. A mobile terminal 1 communicating with plural base stations 4 and 1004 for providing plural different mobile communication networks/services achieves confidentiality of data on plural air links among the plural base stations 4 and 1004 using a single encrypting/decrypting unit 3.
