Abstract

The invention relates to the technical field of communications, and discloses an information transmission method, a client, a server and a computer readable storage medium. The method comprises the following steps: receiving user information input by a user; sending first login request information to the server; receiving response information returned by the server, the response information carrying first encrypted information, and the first encrypted information being information acquired by encrypting a random number generated by the server by an encryption key; decrypting the first encrypted information through the encryption key to acquire the random number, the encryption key being acquired by the client and the server respectively from own local sides; encrypting the random number and a password to acquire second encrypted information; and sending second login request information to the server, the second login request information carrying a user name and the second encrypted information. Verification information for each login is different, so that a replay attack can be prevented; and furthermore, the encryption key is not required to be subjected to network switching between the client and the server, so that the security of the encryption key is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to an information transmission method, a client, a server, and a computer-readable storage medium. Background technique [0002] In the field of video conferencing, security problems often exist in the identity authentication process. In order to improve the security of account passwords, the traditional method is to encrypt the passwords with a digest algorithm before transmitting them. However, today, with the proliferation of network theft technologies, attackers can easily capture packets to obtain encrypted passwords, and then crack them according to the rainbow table, or replay them once without cracking, and then successfully bypass authentication. [0003] In view of the above problems, the prior art publication number CN106533677A discloses a user login method, which specifically includes: first obtaining the user account number and user password input by ...
