Problems solved by technology

[0003] In addition, when using the digital certificate + TLS mechanism, it is necessary to apply for a digital certificate from a CA (Certificate Authority, certificate authority), which brings great inconvenience to the construction of secure data communication in fast application scenarios and lacks application flexibility. The TLS communication protocol requires multi-step negotiation before organizing the ciphertext to be sent. It is too cumbersome in general application scenarios and is not applicable. Instead, important information such as encryption and decryption algorithms, signature algorithms, and keys are exchanged and stored persistently in the In a two-party system, there is a degree of management risk

Abstract

The invention discloses a secure communication method and device based on identity authentication, and the method and device can achieve the flexible and efficient verification of identity informationof two communication sides through electronic seals of two forced authentication sides under the condition that there is no need to apply for a digital certificate from a CA mechanism, and guaranteesthe safety of communication data. The method comprises the following steps that: a request node and a response node respectively manufacture respective electronic seals; the request node and a response node report fingerprint information in electronic seals of the opposite side; the request node encrypts plaintext data by using a random factor to generate ciphertext data, encrypts the random factor by using a public key of the electronic seals of an opposite side to obtain a communication key, and then packages and sends the ciphertext data, the communication key and the fingerprint information to the response node; and the response node compares the fingerprint information in the file package with the reported fingerprint information, decrypts the encrypted private key of the electronicseals to which the response node belongs after successful comparison, decrypts the communication key through the private key to restore the random factor, and analyzes the ciphertext data to obtain plaintext data.

Description

technical field [0001] The invention relates to the technical field of communication security, in particular to an identity authentication-based security communication method and device. Background technique [0002] In order to ensure communication security, the two nodes of the business system need to carry out security design during data communication to identify and verify the identity of the other party. Traditional security solutions mostly use digital certificates + TLS (TransportLayer Security, transport layer security protocol ) mechanism to meet the needs of identification and secure communication. In terms of identity identification, the existing technology adopts a scheme in which the initiator's identity information (such as identity code) is added in the message, and the receiver, after obtaining the identity information, verifies the legality of the other party's identity by checking the database; in terms of security, the existing technology Through the sche...
