Extended Protocol Using Keyless Encryption Based on Memristors

Abstract

The growing interest for keyless encryption calls for new cryptographic solutions with real keyless schemes. This paper introduces an extended protocol using keyless encryption, which is hash-based and generic in cryptography. The sender side and the receiver side will be contained in the protocol. The sender will encrypt a plaintext and then send the cipher to the receiver side, and the cipher used in the protocol will be based on memristor arrays. We will use values of blocks of the plaintext to sort the cipher, which will improve the difficulty of being deciphered. Then, the receiver will receive the cipher and use it to decrypt the plaintext. The method of implementation is thoroughly detailed in this paper, and the security of the protocol is evaluated by testing random plaintexts thousands of times.
