Encryption is the process of scrambling a message. This process converts the original file known as plaintext, into an alternative form known as ciphertext so that only the intended recipient can read it. As more and more information is stored on computers or communicated via networks, the need to ensure that this information is invulnerable to snooping and tampering becomes more relevant. But unencrypted plaintext files are often stored in information systems, partly because the traditional encryption algorithms are not efficient enough to meet real-time requirements. For this application requirement, this paper proposes a fast encryption and decryption algorithm. The design idea is to split a file into many segments and then disorder them and use multiple algorithms to encrypt each section. By testing files of different sizes, compared with the AES and DES algorithms, the encryption and decryption efficiency of this algorithm has been improved, especially the decryption efficiency. This paper's algorithm has high application value in the information system that requires both security and real-time.
