Abstract: A secure network server having an embedded Hyper-Text Transfer Protocol (HTTP) server that is not within its trusted security functionality and that is used to configure the SNS security and networking features.

Abstract: Software updates remedy vulnerabilities in a computer program that has been distributed and installed on a plurality of computers. The software updates are distributed in encrypted form, and then, after the encrypted update has been delivered to a sufficient number of machines, the decryption key for the update is delivered. Since the key is relatively small, it can be distributed to a large number of machines very quickly, thereby reducing the amount of time between when the update is first known to the public, and the time at which all or most machines have installed the update to protect against the vulnerability.

Abstract: A method and a corresponding apparatus for a high availability license management system. The system has a License Backup Server for ensuring uninterrupted service, while at the same time preventing any possible malicious use. According to the present invention, only two servers are required for realizing a secure system. The first server hosts a License Server A 303 and Agent C 305. License Server A 303 contains certificates for all available licenses. The second server hosts a Backup Server B 309 which contains the same licenses of License Server A. Agent C monitors the operation making sure that Backup Server B does not grant any license while License Server A is up and running.

Abstract: A signature generation apparatus and a signature verification apparatus preventing an occurrence of an inappropriate signature verification error. The signature generation apparatus (110) including a signature generation unit (114) calculating signature vector (s, t) for a message m using a private key, and generating signature data S indicating polynomials sl and sh specifying the polynomial s and a polynomial th which is a quotient when the polynomial t is divided by q.

Abstract: A system, method and programmed article of manufacture to perform efficient encryption key updates in encrypted database-as-a-service (DAS) environments using a key registry and key locks. A database as a service environment allows organizations to send their data management infrastructures to a database service provider. The service provider employs data encryption techniques to ensure the privacy of hosted data. The security of encryption techniques relies on the confidentiality of the encryption keys. The dynamic nature of the encrypted database in the DAS model adds complexity and raises specific requirements on key management techniques. The solution is provided by the key registry and by the key update lock, key management process and log management process to allow data update access to data concurrently with encryption key update for the same data.
