Abstract
A method of secure data transfer by physical transport of an electronic storage device wherein the sender, using a type 1 encryption/decryption algorithm, sequentially encrypts data, in any order, with the public key of the receiver and the private key of the sender and then stores then the encrypted data on the transportable electronic storage medium. The receiver, upon receipt of the transportable electronic storage medium, sequentially, in the reverse order of public key/private key use, decrypts using the type 1 encryption/decryption algorithm for said decryption, the data stored on the transportable electronic storage medium with the public key of said sender and the private key of the receiver to provide data in its state prior to by the sender.
