Embodiment Construction

[0017] see figure 1 and figure 2 As shown, a method for data transmission encryption and decryption of the present invention, the method defines a key chain in the code, and the key chain is used as the center to encrypt and decrypt data;

[0018] The encryption operation: carry out the carry number encoding of the key string and the character string to be encrypted, then perform logical operations, and finally perform base64 encoding to obtain the encrypted character string;

[0019] The decryption operation: carry out carry encoding on the key chain and the character string to be decrypted, then perform logical operations, and finally perform base64 decoding to obtain the decrypted data.

[0020] Wherein, the encryption operation is specifically:

[0021] First define the key chain, splicing the date format of the timestamp and the random number to get the dynamic key, so that the results of the data encryption are different every day, which increases the difficulty of de...

Abstract

The invention provides a data transmission encryption and decryption method. The method comprises the steps of defining a key string in code; carrying out encryption and decryption operations on data by taking the key string as a center, wherein the encryption operation comprises the steps of carrying out carry number coding on a character string needing to be encrypted, carrying out logic operation, and carrying out base 64 coding to obtain encrypted character string, and the decryption operation comprises the steps of carrying out carry number coding on the key string and the character string needing to be decrypted, carrying out the logic operation, and carrying out base 64 coding to obtain decrypted character string. According to the method, encryption operation logic and decryption operation logic are in mutual symmetry, so that a logic rule can be modified conveniently; and through adoption of a mode of modifying an encryption logic rule and a key, the data can be rapidly and effectively prevented from being stolen.

Description

technical field [0001] The invention relates to the technical field of payment terminals, in particular to a data transmission encryption and decryption method. Background technique [0002] There are hundreds of millions of URLs on the Internet, some of which are publicly requested by the public, while others are private and used internally by the company. Some data is very precious, and if stolen, it may affect the company's profitability. [0003] For a long time, people have invented various encryption methods. For the convenience of research, these methods are usually divided into two categories: symmetric encryption methods and asymmetric encryption methods. The common feature of the former is the use of single-key technology, that is, the same key is used in the encryption and decryption process, so it is also called a symmetric encryption method; while the common feature of the latter is the use of double-key technology, that is, the same key is used in the encryptio...
