Latest Patents

Cullen's latest patents include innovative methods for establishing secure communications. One of his patents focuses on a method of establishing a network by sharing a secret between two entities. This involves the first entity broadcasting an ANNOUNCE message that announces its identity and details of other entities it is aware of. The message is encrypted using a broadcast encryption scheme common to both entities. Upon receiving and decrypting the ANNOUNCE message, the second entity transmits a SHARE message, which includes a signcryption of the secret, authenticated using specific nonce data.

Another significant patent addresses the functionality of an ad hoc network with a unidirectional link. This method involves a node transmitting an extended allowable hold time value to another node. The node alters its transmission behavior, causing the other node to stop receiving transmissions for an extended period. This innovative approach allows the further node to treat the link as intact during this time, enhancing the reliability of the network.
