Encryption/decryption method

Abstract

The invention discloses an encryption and decryption method, comprising the following steps: selecting plaintext to be encrypted, reading plaintext data through a processor, and reading binary digitaldata in the plaintext by the processor; the AES algorithm is used to encrypt the plaintext data, the plaintext to be encrypted is encrypted by the AES key generator, the AES cipher is an iterative, symmetric key block cipher that can use a 256-bit key and encrypts and decrypts data using a 128-bit block to obtain encrypted plaintext and AES ciphers, adding at least one set of interfering data infront of and behind the plaintext data, and then decrypting the encrypted data. The invention relates to an encryption and decryption method, compared with RSA and AES, the hybrid algorithm of AES andRSA has significant advantages in encryption security, low latency and ciphertext synchronization. The hybrid algorithm of AES and SSL has the smallest delay time difference, and its advantages in encryption security, low latency and effective access authentication are obvious, which brings a better application prospect.

Description

technical field [0001] The invention relates to the field of encryption and decryption, in particular to an encryption and decryption method. Background technique [0002] The encryption and decryption method is a method for encrypting and decrypting plaintext during transmission and reception to avoid file content leakage. However, with the development of science and technology, people have higher and higher requirements for encryption and decryption methods, resulting in traditional encryption and decryption. The method can no longer meet the needs of people; [0003] There are certain disadvantages in the existing encryption and decryption methods. First, the existing conventional encryption and decryption methods include the existing RSA algorithm and the AES algorithm.

[0002] The encryption and decryption method is a method for encrypting and decrypting plaintext during transmission and reception to avoid file content leakage. However, with the development of science and technology, people have higher and higher requirements for encryption and decryption methods, resulting in traditional encryption and decryption. The method can no longer meet the needs of people;

[0003] There are certain disadvantages in the existing encryption and decryption methods. First, the existing conventional encryption and decryption methods include the existing RSA algorithm and the AES algorithm. The end-to-end delay of the existing RSA algorithm is large, and its security and reliability The performance is relatively insufficient; the end-to-end delay of the AES algorithm is small, but the encryption security of the algorithm itself is not enough, at the cost of sacrificing security, and the security is reduced. Therefore, we propose an encryption and decryption method
