  • Patent number: 8533811
    Abstract: A technique allows software developers to develop applications for a smart phone or other terminal by unlocking the terminal so that it can run unsigned applications. A developer registers with a web-based service, agrees to registration terms, and provides authentication credentials. Data which verifies the authentication credentials is provided back to the developer's computer. The terminal is connected to the developer's computer, and via a user interface, the developer requests registration of the terminal. In response, the terminal receives the data from the developer's computer, and provides the data and a unique terminal identifier to the service. If authorized, the service returns a persistent token or license which is stored at, and used to unlock, the terminal. The service can also provide a command which enforces an expiration date. The terminal checks in with the service to determine if the account is in good standing, and is re-locked if warranted.

  • Patent number: 8479001
    Abstract: In a system where a communication device performs secure communication by using a digital certificate, to enable a device of a communication party to verify that a self certificate is certainly generated by a device indicated on the self certificate even if the self certificate is not delivered offline in advance. Based on a master key and a public parameter, a communication device generates an ID-based encryption private key for which a device unique ID is used as a public key. Then, the communication device generates the digital signature of an RSA public key as a ID-based encryption signature by using the ID-based encryption private key. Then, the communication device generates an RSA self signature for the RSA public key, an expiration date, a host name, the device unique ID, and the ID-based encryption signature as the target. Then, the communication device generates a self-signed certificate to include the ID-based encryption signature and the RSA self signature.

  • Patent number: 8478830
    Abstract: A method and apparatus for processing digitally signed messages in which address mismatch errors are detected. In at least one aspect, the number of address mismatch errors reported to a user for a message may be minimized for messages that properly incorporate message portions signed by someone other than the sender of the message, as may be the case where the message contains a conversation thread for example, by performing at least one pre-determined action for digital signatures corresponding to signed data appearing after a message separator. The message separator may indicate that the message contains data from an older forwarded message or from an older message that has been replied to, for example. The at least one-predetermined action may comprise bypassing verification of address matches for those digital signatures, or verifying address matches for those digital signatures but suppressing user notification of any address mismatch errors, for example.
