A realization method of quantum secret key expansion module for AES hardware encryption system

Abstract

The invention provides a method for realizing a quantum secret key expansion module used in an AES hardware encryption system, and belongs to the technical field of information security. The technical solution is: a method for realizing a quantum secret key expansion module for an AES hardware encryption system, comprising the following steps: step A, realization of g function; step B, realization of secret key expansion algorithm. The beneficial effects of the present invention are: the secret key expansion module of the present invention is realized by the quantum reversible circuit structure, which can increase the complexity of the secret key expansion algorithm (2 n -1)! Times, mainly for the operation of 128-bit seed secret key, operate on the 16-byte secret key, expand and generate a new first round of 16-byte secret key, and then perform operations on the first round of secret key to obtain the second round of secret key In this way, ten rounds of secret keys are obtained, which provide secret keys for the encryption and decryption process in the AES hardware encryption system based on quantum circuits, and improve the encryption effect and complexity of the AES hardware encryption system.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method for realizing a quantum secret key expansion module used in an AES hardware encryption system. Background technique [0002] The development of the network society has led to the generation and transmission of a large amount of data every day, especially with the vigorous rise of emerging information technologies such as cloud computing and the Internet of Things, all kinds of information data are rapidly expanding and becoming larger. The era of big data brings great benefits to enterprises and individuals. Here comes new services and opportunities. However, various emerging technologies are still in the initial stage of development, and information protection technology is not mature enough. A large amount of sensitive information is processed, transmitted and stored on the network, and there will inevitably be security issues such as information theft, ta...
