Two-way-security-authentication-based data downloading method and system

Abstract

The invention discloses a two-way-security-authentication-based data downloading method and a two-way-security-authentication-based data downloading system. The method comprises that: a first terminal verifies a second terminal through a symmetric key algorithm to acquire a first verification result; after the second terminal is determined to be a legal terminal according to the first verification result, the second terminal verifies the first terminal through an asymmetric key algorithm to acquire a second verification result; and after the first terminal is determined to be a legal terminal according to the second verification result, the second terminal downloads data which is encrypted through a digital signature algorithm to the first terminal. By the method and the system, the creation of two-way authentication channels and security downloading among different terminals can be realized, and the security and integrity of interactive data are protected.

Description

technical field [0001] The invention relates to the field of information security, in particular to a data download method and system based on two-way security authentication. Background technique [0002] In the existing network information security field, the key can be generated by the public-private key generation module, and different verification parameters can be generated through public-private key exchange and matching, so as to realize the authentication process between different terminals. However, the existing authentication methods are usually one-way security authentication, and after the authentication is completed, a complete security mechanism is not provided for the secure download of data. [0003] At present, only one-way security authentication is used between different terminals of related technologies, which leads to the problem of imperfect security authentication mechanism and data security download mechanism, and no effective solution has been propo...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problem that only one-way security authentication is adopted between different terminals in the related technology, resulting in imperfect security authentication mechanism and data security download mechanism, the present invention has not been raised yet. Therefore, the main purpose of the present invention is to provide A data download method and system based on two-way security authentication to solve the above problems
