Latest Patents

One of her latest patents is titled "Method and system for providing updated encryption key pairs and digital signature key pairs in a public key system." This adaptable cryptographic method allows for the provision of updated digital signature key pairs by utilizing a multi-client manager unit. This unit enables the selection of expiry data, such as digital signature certificate lifetime data, public key expiry data, and private key expiry data, on a per-client basis. The system facilitates a smooth transition from old to new digital signature key pairs by associating stored expiry data with the new key pair.

Another significant patent is the "Information security subscriber trust authority transfer system with private key history transfer." This invention involves a first trusted authority that stores key history data, including private decryption keys for subscribers. It features a key history exportation engine that generates a security key history exportation packet containing encrypted security key history data. A second trusted authority is then able to decrypt this packet, allowing for the secure transfer of key history data, which is made accessible for later use by the subscriber.
