XOR Chain and Perfect Secrecy at the Dawn of the Quantum Era
Cryptography, 2023 In this article, we present a new method that achieves Shannon’s perfect secrecy. To achieve this property, we will introduce the triple XOR cancellation rule. The approach has two execution modes: digital signature and data encryption.

On Fast Verification of Hash Chains
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2010 A hash chain H for a hash function hash(·) is a sequence of hash values 〈xn, xn−1,..., x0 〉, where x0 is a secret value, xi is generated by xi=hash(xi−1) for 1≤i≤n, and xn is a public value. Hash values of H are disclosed gradually from xn−1 to x0. The correctness of a disclosed hash value xi can be verified by checking the equation $x_n \stackrel{?}{=}
