Abstract:
A system for securing information, includes a processor and storage device. The storage device stores information encrypted with one of a first private rolling key and a first public rolling key of an a first asymmetric rolling crypto-key, along with the one first rolling key. The processor has the logic to direct transmission, via a network, of proof of knowledge of the stored one first rolling key to authenticate a user, and of a request for the other of the first private rolling key and the first public rolling key. The processor receives the other first rolling key via the network, responsive to the directed transmission. The processor then decrypts the stored encrypted information with the received other first rolling key, and generates a second asymmetric rolling crypto-key having a second private rolling key and a second public rolling key. The processor encrypts the information with one of the second private rolling key and the second public rolling key. The processor also directs transmission of the other of the second private rolling key and the second public rolling key via the network. The storage device stores the information encrypted with the one second rolling key and the one second rolling key itself.
