  • Publication number: 20080168166
    Abstract: The present invention creates a SOAP message without using DOM by generating a body part by sequentially performing such a process of a message as encryption or signing for each piece of the message, generating a header part by using information acquired during the process, and by combining the body part and the header part. The present invention also breaks a SOAP message without using DOM by acquiring header information with parsing a received SOAP message and sequentially performing decode or verification of a signature of a body part according to the header information.

  • Patent number: 6990585
    Abstract: The present invention provides digital signature techniques using an information terminal, such as a portable terminal, having limited calculation resources. In one embodiment, a signature demandant generates a document to be signed, and an agent receives this document. The agent generates summary text for this document, and transmits the summary text to a signatory, and the signatory displays the summary text using his or her information terminal. The signatory confirms the contents, employs a private key stored in his or her terminal to sign (encrypt) the summary text. The signatory thereafter transmits a signature value to the agent, who generates a signed document that includes the signature value. Finally, the signature demandant verifies (decrypts) the received signed document using the public key of the signatory and confirms the contents.

    Abstract: To provide an information processing apparatus, a server apparatus, a method of an information processing apparatus, a method of a server apparatus, and an apparatus executable program. An information processing apparatus uses signed integrity values unique to software configuration and asserting integrity of initial codes of a networked server. The server apparatus generates keys used for certifying the server apparatus(S810, S820, S830). One of the keys are certified by a third party to generate a digital signature (S840). The digital signature is attached to the integrity values and the signed integrity values are transmitted to the information processing apparatus for allowing the information processing apparatus to have secure services through the network (S850, S860).
