Communication method and device and readable storage medium

Abstract

The invention provides a communication method and device and a readable storage medium. The communication method comprises the steps of obtaining strategy information sent by a communication object, wherein the strategy information comprises a target password generation strategy encrypted through a first public key; generating a decryption key according to preset identity identification information; decrypting the encrypted first private key through the decryption key, wherein the first private key corresponds to the first public key, and an encryption key of the first private key is generatedaccording to the identity identification information; decrypting the encrypted target password generation strategy through the first private key to obtain the target password generation strategy; generating a communication password according to the target password generation strategy, and encrypting the communication password through a second public key to obtain an encrypted communication password; and sending the encrypted communication password to the communication object. The communication method is used for improving the safety of the secret key, and then safe and reliable communicationis achieved.

Description

Technical field [0001] In particular, the present application relates to communication technologies, and in particular, there is a communication method and a device, a readable storage medium. Background technique [0002] In the prior art, when data communication is performed between the server and the device, the data is typically encrypted by the symmetrical communication password. For the communication password, the server can be generated by mutual authentication before the server is formally interacting data. [0003] However, whether it is the server or the device, the applied encryption key is a plaintext data, causing the encryption key to be intercepted by other devices and counterfeit, that is, the key has a low security, thereby causing communication Not safe and reliable. Inventive content [0004] It is an object of the present application to provide a communication method and device, a readable storage medium to improve the security of the key, thereby achieving s...

AI Technical Summary

Problems solved by technology

[0003] However, whether it is the server or the device, the encryption key applied is plaintext data, which makes the encryption key easy to be intercepted and counterfeited by other devices, that is, the security of the key is low. not safe enough
