  • Patent number: 7835519
    Abstract: To provide a method and a system for creating a mini time key from a time key, a plurality of mini time keys are created within a unit time period. First, a unit time decryption key is prepared immediately after the unit time is created. Then, the last mini time key is created by applying a one-way function to the unit time decryption key. A desired mini time key is created by applying the one-way function to a mini time key following the desired mini time key. In other words, the mini time keys are created as a timed series arranged in a descending order beginning with the last mini time key. In this manner, even when a specific mini time key is externally leaked for a specific reason, a following mini time key in a timed series can not be created by using this mini time key. In addition, even when the mini time keys are sequentially published, the security of the unit time decryption key is maintained.

  • Patent number: 7836306
    Abstract: A process for establishing secure mutual trust includes generating a one-time-password. The one-time-password is transferred between the devices in a communication occurring off of the network. Each device generates a set of authenticators by hashing a plurality of sub-strings of the password and the device's authentication certificate with a respective set of nonces. The devices exchange the respective sets of authenticators. Each device then alternates revealing its respective set of nonces and its authentication certificate in a multi-stage process. The devices re-calculate the authenticators based upon the respective set of nonces and authentication certificate revealed by the other device along with the one-time-password sub-strings that it posses. If each device determines that the authenticators re-calculated by the given device matches the authenticators previously received from the other device, secure mutual trust is established.

  • Patent number: 7809648
    Abstract: A software licensing system includes a license generator located at a licensing clearinghouse and at least one license server and multiple clients located at a company or entity. When a company wants a software license, it sends a purchase request (and appropriate fee) to the licensing clearinghouse. The license generator at the clearinghouse creates a license pack containing a set of one or more individual software licenses. The license generator digitally signs the license pack and encrypts it with the license server's public key. The license server is responsible for distributing the software licenses from the license pack to individual clients. When a client needs a license, the license server determines the client's operating system platform and grants the appropriate license. The license server digitally signs the software license and encrypts it using the client's public key. The license is stored locally at the client.
