  • an input for the reception of information;

    an encryption algorithm to encrypt the information;

    an electronic recorder to record the encrypted information;

    a decryption algorithm to decrypt recorded information;

    at least one programmable memory to store at least one cryptographic key for use with the encryption and decryption algorithms;

    a tamperproof enclosure to protect the input and at least one programmable memory from access or alteration; and

    a trusted agent to generate at least one cryptographic key to be used in conjunction with the encryption and decryption algorithms, the trusted agent programming any generated cryptographic key into at least one programmable memory for use with the encryption and decryption algorithms and, upon request, verifying the authenticity of the recorded information by decrypting the recorded information using at least one cryptographic key.
