Embodiment Construction

[0025] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0026] see figure 1As shown, a key security system based on key sharing and hardware binding includes a mobile client and a server, and data transmission is performed between the mobile client and the server through an SSL / TLS secure transmission channel;

[0027] The mobile client is a smart phone terminal or a smart tablet terminal. The user sends a new user registration or the second part of the key or a key update request to the server through the mobile client; the server receives the new user registration or the secon...

Abstract

The invention discloses a key security system based on key sharing and hardware binding, which is used to solve the problems of inconvenient use, easy leakage and low security in existing key storage security, including mobile client and On the server side, the mobile client is used to send the request content to the server and receive the feedback real-name verification instruction. When the real-name verification instruction is received, the real-name verification is performed. After the verification is successful, the hardware information of the mobile client is detected, and a hash is generated based on the hardware information. , and then send the hardware information and the corresponding hash to the server; receive and store the first part of the key fed back by the server and the hash of the complete key; Part of the key is leaked and cannot be used on other terminals. At the same time, the server does not save the complete key to prevent the server from being attacked and causing the key to leak.

Description

technical field [0001] The invention relates to the technical field of key security storage, in particular to a key security system based on key sharing and hardware binding. Background technique [0002] Distributed digital identities use the DPKI system to realize secure storage of identities and verification of signatures, and key security is the key to the security of the entire system. Traditionally, there are mainly two types of key storage schemes: one is to realize key storage and data encryption, signature and verification through proprietary hardware wallets; the other is to store user keys through files, and realize data encryption and signature through software and signature verification; however, both storage solutions have shortcomings. The hardware key wallet can meet the security level requirements, but the cost is high and it is inconvenient to use. Especially in mobile application scenarios, it needs the support of the underlying hardware manufacturers and ...
