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.

Abstract: A context manager supports creation, storage and retrieval of data to implement state maintenance in a vault process using “scoping” of multiple levels of storage. A user request is initiated by invoking an URL with embedded Application Domain and Instance Context. The URL request is processed by a Vault Supervisor to obtain a user ID and password to initiate a vault process running in a secure vault for the user. On vault process start up, access to the vault encryption/decryption keys are made available to the request. A global context file stored on disk is decrypted and read in to memory. If the global context file does not exist, a new global context file is created on disk. For each Application Domain, the application context is decrypted and read in to memory. If an application context file does not exist, a new application context file on disk is created based on the request. All Instance Context files are scanned to determine if they have expired.

Abstract: A digital signature system that employs a temporary digital ID signed by using a private key, so that the digital ID can be used as a proxy for a specific period of time and for a specific purpose. When a signature is requested by a server application, a user does not use his or her private key, but employs a temporary key generated using the private key. A temporary certificate for the temporary key is signed using the user's private key. The temporary certificate includes information concerning the period of time during which the temporary certificate is valid and information concerning the purpose for which used. Upon receipt of a request from an application that a document be signed, a client transmits to the server a document signed using the temporary key, the temporary certificate and a user's certificate. First, the server examines the signature; second, it determines whether the temporary certificate is still effective, i.e.

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: An evaporative fuel processing system adapted to be capable of detecting abnormality of an evaporative emission control system for storing, in a canister, evaporative fuel from a fuel tank for holding fuel to be supplied to an internal combustion engine, and purging evaporative fuel into the intake system of the engine. A first control valve is arranged across a passage extending between the fuel tank and the canister. A second control valve is arranged across a passage extending between the canister and the intake system of the engine. A third control valve is provided for an air inlet part of the canister communicatable with the atmosphere. Through operating these control valves to open and close them, the evaporative emission control system is negatively pressurized, and abnormality of this system is detected based on the pressure detected in this negatively pressurized state thereof.
