Problems solved by technology

[0003] In the existing RPA technology, general encryption algorithms are often used for data transmission or data verification. The general encryption algorithms work in a fixed mode and lack randomness.
Since RPA technology is characterized by centralized design and large-scale deployment, many RPA robots will execute the same business logic, and insufficient encryption randomness will increase the risk of cracking

Abstract

The invention provides a data random encryption and decryption method, device and system, belongs to the technical field of information security, and can be applied to the financial field or other fields. The data random encryption method comprises the following steps: randomly generating a serial number, and obtaining an encryption key according to the serial number; encrypting the encryption key to obtain a key ciphertext, and generating a header information plaintext according to the key ciphertext and the serial number; and encrypting the information plaintext according to the encryption key to obtain an information ciphertext, and generating a transmission data ciphertext according to the header information plaintext and the information ciphertext. According to the invention, the randomness of the encryption mode and the data security can be improved, and the risk of plaintext data leakage is reduced.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to a data random encryption and decryption method, device and system. Background technique [0002] Robotic Process Automation (RPA) technology is an automation technology that uses computer programs to simulate human-computer interaction and realize specific business processes. Its technical features include machine-assisted manual processing of various business data in the computer system. For many secret-related industries or positions, how to ensure that sensitive data is not leaked and the data transmission process is credible during process automation is an important task. [0003] Existing RPA technologies often use general-purpose encryption algorithms for data transmission or data verification. The general-purpose encryption algorithms work in a fixed mode and lack randomness. Since RPA technology is characterized by centralized design and large-scale...
