Secure communication method, device, mobile terminal and storage medium

Abstract

The present invention relates to the technical field of information encryption, in particular to a secure communication method, device, mobile terminal and storage medium, comprising the steps of: generating a secret key, an algorithm and a ciphertext, performing an obfuscation operation, performing a summary operation to generate signature data; Encode, generate a new string, and send it to the server together with the AppID of the caller as a parameter; obtain the license data according to the AppID, verify the validity of the data and service call permissions, and confuse the secret in the license data with the ciphertext in the parameter to generate a signature , perform signature comparison and verify legality; decrypt the ciphertext in the parameter to obtain the secret key and then decrypt it twice, generate plaintext and send it to the transaction core, obtain the response result data, encrypt and generate ciphertext and send it to the client; apply the secret key and algorithm Decrypt to generate plaintext. The invention adopts multiple encryption methods to ensure the safe and stable operation of the system and avoid information leakage.

Description

technical field [0001] The present invention relates to the technical field of information encryption and decryption, in particular to a secure communication method, device, mobile terminal and storage medium. Background technique [0002] In the information age, communication is an indispensable foundation, which not only facilitates the connection between people but also is more conducive to social management. However, how to ensure the security of communication information is the top priority. At this time, information encryption must be introduced. technology. [0003] At present, the network communication encryption platforms in the domestic market are mainly divided into two categories: dedicated encryption chips and software encryption systems. The development cost of dedicated encryption chips is high. In most cases, only one encryption algorithm can be implemented, and it is difficult to connect well with upper-layer applications, so that most dedicated encryption ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to propose a secure communication method, device, mobile terminal and storage medium to solve the deficiencies in the above-mentioned background technology, and to solve economic problems caused by the single encryption method between existing systems, user passwords being cracked by violence, and confidential information leakage. In order to avoid serious problems such as loss and privacy exposure, multiple encryption methods are used to shield security vulnerabilities to prevent user privacy information or important business data from being stolen, and data from being intercepted or tampered with by a third party, thereby ensuring the safe and stable operation of the system. Two checkpoints for password verification to avoid information leakage and ensure that the caller of the data access interface has matching permissions
