Implementation method of quantum key extension module for AES hardware encryption system

Abstract

The invention provides an implementation method of a quantum key extension module for an AES hardware encryption system, and belongs to the technical field of information security. According to the technical scheme, the implementation method of the quantum key extension module for the AES hardware encryption system comprises the following steps of A, implementing a g function; and B, implementinga key extension algorithm. The key extension module has the beneficial effects that the key extension module is constructed and realized by a quantum reversible circuit, and the complexity of the keyextension algorithm can be increased by (2n-1)! times; the method is mainly used for operating a 128-bit seed key; operation is performed on the 16-byte key; a new first round of 16-byte key is generated through extension, then the first round of key is operated to obtain a second round of key, in this way, a ten-round key is obtained, the key is provided for the encryption and decryption processin the AES hardware encryption system based on the quantum line, and the encryption effect and complexity of the AES hardware encryption system are improved.

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...
