Abstract: To authenticate an authentication reference apparatus, authentication information generation reference data is transmitted to the authentication reference apparatus. First authentication reference data generated by the authentication reference apparatus using the authentication information generation reference data is acquired from the authentication reference apparatus. Second authentication reference data is generated using key information complying with a method of generating the first authentication reference data and the authentication information generation reference data. The first authentication reference data is compared with the second authentication reference data. The authentication reference apparatus is authenticated based on the comparison result.

Abstract: Even when encoded (compressed) image data appended with an error-detecting code is encrypted, the apparatus which receives and reproduces that image data can execute a normal process without any insignificant re-send request and the like. To this end, encoded image data is input, and first error-detecting encoding information contained in its header is checked to determine whether or not an error-detecting code is appended. If it is determined that the error-detecting code is appended, the first error-detecting encoding information is changed to indicate the absence of an error-detecting code, and is saved as second error-detecting encoding information. Then, the encoded image data is encrypted.

Abstract: To generate and verify signature data using a known signature algorithm whose safety is ensured from the viewpoint of calculation quantity and ensuring the authenticity thereof over a long time period. A message to be signed is transmitted, a padding-data item is added to the message, and a signature-data item of the message with the padding-data item added thereto is generated by using a hash function and a public-key cryptosystem. The addition step and the generation step are performed a predetermined number of times by using the signature-data item, as the padding-data item, and the signature-data items generated the predetermined number of times and the padding-data items added the predetermined number of times are externally transmitted with the message.

Abstract: The present invention stores and manages only one piece of key information even if contents information includes a plurality of partial contents arranged in a sequence, and the partial contents are encrypted with different keys. When a piece of contents information includes four partial contents or divided into four partial contents, a key for each of four node positions is generated through four steps of operations from a key for the top root. Node keys P (i, 1) and P (i, i) at both sides are generated by a one-way function from node keys P (i−1, 1) and P (i−1, i−1) at the upper i−1th layer, and a node key P (i, m) (m=2, 3, . . . , i−1) are generated by a one-way function which can generate the keys from any of node keys P (i−1, m−1) and P (i−1, m) at the upper i−1th layer, where jth node key at the ith layer is represented as P (i, j) (j=1, 2, . . . , i−1). Then, each of partial contents is encrypted with key information generated at a terminal layer. If only a root key is saved, one encrypting key can be generated for a range of partial contents arranged in a sequence.
