Latest Patents
DeSa's latest patents demonstrate his commitment to securing data through innovative methodologies. One notable patent is for "Securing multifactor split key asymmetric crypto keys." This invention presents techniques for safeguarding asymmetric crypto-keys, which involve a public key and a split private key containing multiple portions. The process ensures that a first factor, crucial for generating one portion of the split private key, remains under the user's control and is not stored in a persistent state. The second portion of the split private key is held by an entity separate from the user, completing the security measures when both portions are combined.
Another significant patent is "Roaming utilizing an asymmetric key pair," which details a method for generating a portion of a split private key at different network locations. This process utilizes two distinct symmetric keys and involves transmitting an encrypted first factor essential for deriving the private key portion after successful user authentication at the second location.
