The invention relates to the technical field of information security, in particular to a method for encrypting and transmitting information, which comprises the following steps: providing to-be-encrypted initial information, randomly generating an initial key, adding filling bytes into the to-be-encrypted initial information through a filling method to obtain a filling plaintext, performing primary encryption on the filling plaintext through a symmetric encryption algorithm to obtain a primary encrypted ciphertext; determining the number of times of secondary encryption and an encryption method of secondary encryption according to the initial key, and performing secondary encryption on the primary encrypted ciphertext to obtain a secondary encrypted ciphertext; performing verification calculation on the secondary encrypted ciphertext to obtain verification information, and inserting the verification information into the secondary encrypted ciphertext in a segmented manner according to the key to obtain a tertiary encrypted ciphertext; and transmitting the third encrypted ciphertext. According to the method for encrypting and transmitting the information provided by the invention, the security of the information in the transmission process is improved.
Description
【Technical field】 [0001] The invention relates to the technical field of information security, in particular to a method for encrypting and transmitting information. 【Background technique】 [0002] At present, communication technology has been integrated into all aspects of life. From online shopping, finance to daily social interaction, information is transmitted all the time, and information security has become an important aspect of life. Encryption algorithm is the core technology to ensure the safe transmission and storage of information. With the improvement of computer storage capacity and computing power, traditional encryption methods have low security and low encryption efficiency, making it possible to crack traditional encryption algorithms through exhaustive methods and mathematical statistics methods, which has a negative impact on communication network data security. influences. 【Content of invention】 [0003] In order to solve the problems of low security...
