Abstract
A method for improving communication security implemented by a sending device. The method includes the sending device generating a first hash token based on a K generation hash (H) value of a seed known only to the sending device, where K is an integer value greater than one, and sending a first message that includes the first hash token. The method further includes the sending device performing a reversible combination of a K−1 generation hash (H) value of the seed and a hash of the first message to generate a second hash token, and sending the second message that includes the second hash token.
