摘要： 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.

摘要： It is possible to safely constitute a key management method having an access structure equivalent to the hierarchical key management method with a small amount of calculations. The method includes: a setting step for setting a set (,) of the number of times a one-way hash function is executed for each of the elements of the rank i; a key generation step for generating two separate keys for the elements as the value of the number of times the one-way function has been executed corresponding to the set of the number of times which has been set for the elements of the two original keys for each of the elements; and a key delivery step for delivering the two separate keys for the elements to each of the elements. Furthermore, the method includes an initial key generation step for calculating N keys with a route node positioned at the most significant node when generating a key at each node from a parent node and performing key delivery according to the hierarchical relationship expressed in a directed graph having no cycle; and a node key generation step for generating the value of the number of predetermined times the one-way function is executed according to the execution specification for M keys (M≦N) among the N initial keys in each node, as the M node keys for the node.

摘要： An object of this invention is to protect the right of a content holder without any necessity of a special storage medium incorporating a copyright protecting mechanism when the content holder does not coincide with a content creator. Information for encryption key generation is input. An encryption key is generated from the information for encryption key generation. Encryption key verification data is acquired from a storage medium, and the validity of the generated encryption key is authenticated based on the verification data. Generated data is encrypted by using the encryption key whose validity is authenticated by the authentication. The encrypted data is stored in the storage medium.
