The invention discloses an authentication method, device and system based on an untrusted environment. The method comprises: an intelligent contract interface acquiring certificate application data submitted by any participant authentication party; the intelligent contract interface issuing the certificate application data to each participant authentication party, so that each participant authentication party signs the certificate application data based on a private key; receiving a signature of each participant authentication party for the certificate application data, and generating a groupsignature according to the signature of each participant authentication party for the certificate application data; authenticating the legality of the group signature according to the group public keycorresponding to the group signature; and if the authentication is passed, generating a digital certificate for the participant authenticator submitting the certificate application data. According tothe invention, the problem of high difficulty in constructing the PKI system by small and micro users is solved.
Description
technical field [0001] The present application relates to the technical field of cryptography, in particular, to an authentication method, device and system based on an untrusted environment. Background technique [0002] The existing public key infrastructure (Public Key Infrastructure, PKI) system of the certificate system is based on an authoritative third-party certification body. The industry standard certificate format supports better, and the cost of custom certificate format is higher, which is suitable for industry and enterprise customers. For small and micro users, it is difficult to build their own PKI system, and there is also a lack of endorsement from trusted institutions. Contents of the invention [0003] The main purpose of this application is to provide an authentication method, device and system based on an untrusted environment, so as to solve the problem of difficulty in building a PKI system for small and micro users. [0004] In order to achieve t...
