Data communication method and device

Abstract

The invention provides a data communication method and device. The method comprises the following steps: transmitting an identity authentication request to a server, wherein the identity authentication request comprises user public key information; receiving authentication response information of the identity authentication request, wherein the authentication response information comprises server public key information; conserving the server public key information; transmitting a key negotiation request to the server, wherein the key negotiation request comprises user encryption information; receiving negotiation response information of the key negotiation request, wherein the negotiation response information comprises encryption information of a communication key; determining the communication key according to the negotiation response information; generating a variety of levels of encryption ways in accordance with a preset encryption strategy; selecting the encryption way of a target level according to the security level of business data; and using the encryption way of the target level to encrypt the business data and transmitting the target level and the encrypted business data to the server. The data communication method provided by the invention can improve the encryption strength and the encryption flexibility.

AI Technical Summary

Benefits of technology

This new technology allows two devices (the phone or computer) that want encrypted communications exchange their private keys without revealing them over an open network like internet). They also use these shared secret keys instead of relying solely upon one device's own password when encrypting sensitive documents such as credit cards. These techniques increase the overall efficiency of secure transactions by making it more difficult for hackers who may gain access through brute force attacks.

Problems solved by technology

This patented technical problem addressed by the present patents relates to improving the efficiency or safety of transmitting secure digital content over wireless networks such as cell phones without compromising its privacy rights. Current methods like Secure Sockets Layer SSL have limitations that make them vulnerable against attacks from malware on these devices.
