Embodiment Construction

[0101] The characteristic of the fast quantum-safe asymmetric encryption method is that it allows each user to have two keys, one key can be made public for encryption, and one key can only be kept private for decryption. In this way, there is no need to worry about the secret key being leaked during the transmission process on the Internet. When the two parties agree to transmit information on the Internet, the sender uses the receiver's public key to encrypt the file or message, and the receiver uses its own private key to decrypt the ciphertext after receiving it.

[0102] Each user can obtain two keys from the designated CA center. The CA center is an institution that registers and registers users, and generates, distributes and manages keys. It utilizes the key generation component to generate a pair of public key and private key of the user.

[0103] This encryption method can be realized with logic circuit chip or programming language, and it comprises three parts: (1...

Abstract

The invention discloses a fast quantum secure asymmetrical encryption method, and belongs to the technical field of passwords and computers. The method comprises three steps of secret key generation, encryption and decryption; a user owns two secret keys, one is owned only privately and called a private key, the other can be made public and is called a public key, the public key is obtained from the private key, and the private key cannot be inferred from the public key; the public key is used for translating plain text into cipher text in group (encryption), and the private key is used for recovering the plain text from the cipher text (decryption); by means of an additive multivariable permutation problem (AMPP) and an anomalous subset product problem (ASPP), the safety of the private key and the plain text is guaranteed. The method has the advantages of quantum computation resistance, high safety, small modulus, high computation speed, public technology and the like, and the method can be used in confidential storage and transmission of any files and data blocks in mobile phones, computers and relative communication networks.

Description

(1) Technical field [0001] Asymmetric encryption method (also known as public key encryption method) belongs to the field of cryptography and computer technology, and is one of the core technologies of information security and network security. (2) Background technology [0002] The development of cryptography has gone through three stages: classical cryptography, symmetric cryptography and public key cryptography. In 1976, American scholars Diffie and Hellman proposed the idea of ​​public key cryptography, marking the advent of public key cryptography. At present, the commonly used asymmetric encryption techniques include the RSA system and the ElGamal system (see "Applied Cryptography", written by Bruce Schneier in the United States, translated by Wu Shizhong, Zhu Shixiong, etc., Mechanical Industry Press, January 2000, pages 334-342 ). In order to improve security and computing speed, the ElGamal system is often implemented on the elliptic curve. At this time, it is cal...
