Embodiment Construction

[0053] The present invention will be further described below in conjunction with the accompanying drawings.

[0054] refer to figure 1 , the specific implementation steps of the present invention are further described.

[0055] Step 1, send authentication request:

[0056] Using the identity signature algorithm, the user who sends the request in the user domain signs the message, and obtains the hash value of the message and the signed message.

[0057] The message includes the time stamp of sending the request in the user domain, the identity of the user, and the identity of the information service entity accessed in the entity domain.

[0058] The specific steps of the identity signature algorithm are as follows:

[0059] Step 1: Composing a message with the time stamp of the request sent in the user domain, the identity of the user, and the identity of the information service entity accessed in the entity domain;

[0060] Step 2, using a cryptographic hash function to c...

Abstract

The invention discloses a cross-domain authentication method for information service entities based on trust values of domain proxies, and mainly aims to solve the problems of high computational complexity, high communication overhead and complex certificate management based on public key infrastructure in a current cross-domain authentication process. According to the technical scheme, the methodcomprises the following steps: verifying the legitimacy of user identity with an identity-based signature algorithm; connecting direct trust vectors extracted from transaction information tables of the domain proxies with a connection operator; and merging trust vectors on a plurality of recommended paths by a merging operator to judge whether the domain proxies trust each other or not. Through adoption of the method, the problems of complex certificate management, high computational complexity and high communication overhead in a cross-domain authentication process based on a public key infrastructure authentication system in the prior art are solved, and the practicability and efficiency of the cross-domain authentication process are improved while guaranteeing the authentication accuracy between the domain proxies.

Description

technical field [0001] The invention belongs to the technical field of communication, and further relates to a cross-domain authentication method of an information service entity ISE (Information System Entity) based on a domain agent DA (Domain agent) trust value in the technical field of network communication. The present invention can establish a trust relationship between trust domains by calculating trust values ​​between domain agents in a distributed network environment with limited resources, and provide security for users of a trust domain to access resources of information service entities across domains Assure. Background technique [0002] Establishing a trust relationship between domain agents is an important step to improve the confidentiality and security of users' personal information in the network. Cross-domain authentication refers to the technology and process of mutual authentication between domain agents in different domains. In recent years, with the ...
