Verification data generating apparatus, data verification apparatus and storage medium for storing verification data generating program

According to the present invention, piracy of secret data is prevented without an attack detecting circuit or data deleting circuit. In a secret data processing unit, a cell contains fluid in a sealed space. Code generators arranged in the sealed space receive a code generation request to generate codes specified by the pressure value of the fluid. A key generator disposed in the sealed space generates encryption keys/decryption keys specified by the generated codes. An encryptor/decryptor also disposed in the sealed space receives requests for secret data encryption/requests for encrypted secret data decryption, and outputs code generation requests to the code generator to encrypt the secret data/decrypt the encrypted secret data by using the generated encryption key/decryption key. Both codes and encryption keys/decryption keys generated and used, are not statically stored in the cryptographic processing unit.
