Problems solved by technology

The shortcomings of this method are: first, the identity of the bridge IKI system needs to be trusted and maintained, which increases the maintenance burden; second, when the number of IKI systems increases, the storage burden of the bridge IKI system increases. If multiple bridge IKI systems are set, Increase the user's storage burden
The disadvantages of this method are: since

Embodiment Construction

[0052] Attached below figure 1 The present invention is further described.

[0053] Step 1, build a trust alliance blockchain.

[0054] According to the number of node servers in the trust alliance that the blockchain communication capability can accommodate, set the number of public key infrastructure PKI domains and identity-based cryptosystem IBC domains respectively.

[0055] The certificate server in each public key infrastructure PKI domain and the domain proxy server in each identity-based cryptographic system IBC domain are used as node servers of the trust alliance blockchain.

[0056] The certificate server in the public key infrastructure PKI domain issues certificates for the domain proxy server in the identity-based cryptosystem IBC domain.

[0057] Select the hash function according to the size of the certificate to generate the hash value of the certificate.

[0058] Use the hash value of the certificate as the first block, save it in the block body, and get ...

Abstract

The invention discloses a cross-domain server identity authentication method based on a trust alliance block chain, comprising the following steps: (1) constructing the trust alliance block chain; (2)authenticating an identity of a server accessed by a user in a public key infrastructure (PKI) domain; (3) authenticating an identity of a server accessed by a user in an identity-based cryptosystem(IBC) domain; (4) setting valid time of each authentication ticket; (5) authenticating the identity of the server accessed by the user in the PKI domain again; and (6) authenticating the identity of the server accessed by the user in the IBC domain again. The method constructs the trust alliance block chain, realizes inter-domain mutual authentication by virtue of mutual authentication among nodesin the trust alliance block chain, then realizes cross-domain authentication on the server, reduces maintenance burden of a bridge center system, reduces computation amount and communication trafficof a user side and has good practicability and expansibility.

Description

technical field [0001] The invention belongs to the technical field of network communication, and further relates to a method for cross-domain authentication server identity based on trust alliance block chain in the technical field of network security. The present invention can be applied to a method for authenticating the identity of the accessed server when a user requests cross-domain access to the server in the certificate-based public key infrastructure PKI (Public Key Infrastructure) and identity-based cryptosystem IBC (Identity-Based Cryptography) domains . Background technique [0002] At present, certificate-based public key infrastructure PKI and identity-based cryptographic system IBC are widely used in the trust domain authentication framework based on public keys. When an identity-based cryptographic system IBC domain user accesses a public key infrastructure PKI domain server, or a public key infrastructure PKI domain user accesses an identity-based cryptogra...
