Cryptographic algorithm encryption and decryption system

Abstract

The invention relates to the technical field of encryption and decryption. The invention further discloses a cryptographic algorithm encryption and decryption system. The system comprises an information input unit, a receiving buffer module, an encryption and decryption chip, an output buffer module and a display unit, the output end of the information input unit is connected with the input end ofthe receiving buffer module; the output end of the receiving buffer module is connected with the input end of the encryption and decryption chip; wherein the output end of the encryption and decryption chip is connected with the input end of the output buffer module, the output end of the output buffer module is connected with the input end of the display unit, and the encryption and decryption chip comprises a key generation unit, an operation unit, an encryption unit, a key expansion module, a decryption unit and a collection unit. The problems that only some online tools on the market provide encryption and decryption of individual encryption algorithms, no system truly integrating common encryption algorithms is provided for users to use, and in addition, the online tools have the defects that the online tools cannot be normally used and are inconvenient to operate when network connection does not exist are solved.

Description

technical field [0001] The invention relates to the technical field of encryption and decryption, in particular to a cryptographic algorithm encryption and decryption system. Background technique [0002] So far, a large number of major information leakage incidents at home and abroad have been exposed by the media. The leaked information ranges from hundreds of thousands to hundreds of millions. The harm of information leakage has also attracted great attention from the whole society. Information leakage has become a risk source of security problems, and from the perspective of the types of information leaked by institutions, it is mainly divided into two categories, personal information and confidential information. Technical secrets and other confidential information, in the wave of rapid development of the big data industry, personal information security and privacy protection are facing a severe situation. As the core content of data information, personal information i...

Problems solved by technology

At present, there are frequent personal information leakage incidents in some industries, and criminals even use the massive data information that has been leaked to conduct correlation analysis, and even make customer portraits. After accurately locating the user's identity, they carry out precise fraud. Information leakage involves all walks of life: Finance, government agencies, public institutions, communication operators, IT information technology, education and scientific research, manufacturing, life services, energy, social security, transportation, etc., data encryption is the core of preventing data leakage, so it is involved in various fields Encryption and decryption of information. In modern cryptography, common encryption systems can be divided into three categories, symmetric encryption algorithm, asymmetric encryption algorithm and Hash algorithm. At present, encryption algorithms play a very important role in both academia and other application fields. However, there are only some online tools on the market that provide encryption and decryption of individual encryption algorithms, and there is no system that truly integrates common encryption algorithms for users to use. In addition, the disadvantage of using online tools is that they cannot be used normally when there is no network connection. Inconvenient to operate
