Method for establishing trusted link between client and server

Abstract

The invention discloses a method for establishing a trusted link between a client and a server. The method comprises the steps that 1, a client is opened for the first time to initiate a request to aserver, and the request does not transmit any parameter and is only used for obtaining a public key generated by the server; 2, the server generates a pair of public key and private key by using an RSA algorithm, reserves the private key, and sends the public key to the client; 3, after receiving the public key, the client reserves the public key, additionally generates a pair of public key and private key, reserves the private key and sends the public key to the server, and the request transmits the public key generated by the client; 4, after the server receives the public key, the public key is reserved, and meanwhile a session key used in symmetric password encryption is generated through a pseudo-random number generator. In the data interaction process, the data encryption and decryption speed is increased, the user experience is improved, the safety of user data is ensured, and the advantages of multiple encryption schemes are combined, so that malicious attacks are not likely tohappen.

Description

technical field [0001] The invention relates to the technical field of video communication, in particular to a method for establishing a trusted link between a client and a server. Background technique [0002] With the rise of the Internet of Things, remote viewing of videos is becoming more and more popular in all walks of life, especially in the era of very high usage of mobile devices, and there will be more and more scenes of viewing remote historical videos with mobile terminals, so the security of personal video data A certain guarantee is required. The invention discloses a scheme of data encryption technology to ensure the security of data communication between a client end and a server end, including encryption and decryption processing of communication data. At present, the solutions on the market all use symmetric encryption or public key encryption to simply ensure the encryption and decryption of data. However, in symmetric encryption, since the encryption and...

Problems solved by technology

At present, the solutions on the market all use symmetric encryption or public key encryption to simply ensure the encryption and decryption of data. However, in symmetric encryption, since the encryption and decryption keys are the same, symmetric encryption is simply used. The delivery problem has become a big loophole, and in the process of public key encryption, the data processing speed is much lower than that of symmetric encryption, resulting in a bad experience. In view of this, a method that can not only ensure data security, but also Solutions to Guarantee Data Processing Speed
