The invention relates to the field of information security and technology, particularly provides an identity-based anonymous authentication method, a server and user terminal equipment, and aims to solve the technical problem that an attacker can steal user information under the condition that the server is hijacked, and the method specifically comprises the following steps: generating a complete private key and a complete public key according to a user ID in a registration request; the user terminal equipment generates a knowledge signature according to the complete private key and the complete public key; and authenticating the user terminal equipment according to the knowledge signature and the corresponding sending timestamp, if the authentication succeeds, calculating an authentication parameter and sending the authentication parameter to the user terminal equipment, so that the user terminal equipment authenticates the server according to the authentication parameter, and otherwise, interrupting the communication connection with the user terminal equipment. According to the technical scheme provided by the invention, when the two communication parties are subjected to security authentication, even if the server is malicious, an attacker cannot obtain any sensitive information of the user, so that the privacy of the user is protected.
Description
technical field [0001] The invention relates to the field of information security and technology, in particular to an identity-based anonymous authentication method, server and user terminal equipment. Background technique [0002] With the rapid development of mobile Internet and wireless communication, and the increasing popularity of smart devices such as smartphones and smart watches, more and more netizens use mobile devices to collect, transmit and store data for personal business such as instant messaging and online shopping and mobile payment. However, these data often may contain personal sensitive information, etc., and there are often risks such as eavesdropping, counterfeiting, and replay during data interaction. [0003] For the above-mentioned risks, using a mutual authentication mechanism between the two parties in the mobile Internet can achieve the effect of reducing risks. This mechanism means that the two communicating parties (generally referring to the...
