Problems solved by technology
First of all, the digital certificates used for exchanging in the distributed trust mechanism contain personal attribute information, which is sensitive information, so in the process of providing certificates, changes in the Internet network environment and structure may lead to sudden changes in attribute information and thus prompt Trust relationship establishment failed
Secondly, in the distributed trust mechanism, the exchange of each software Agent certificate has an access control policy, and the attribute information on the certificate is exposed only when the conditions of the access control policy are met, thus increasing the complexity of trust relationship establishment; finally , in the distributed trust mechanism, each time the software Agent establishes a trust relationship, it needs to re-provide the necessary certificates or passwords, etc., wasting resources and time

Embodiment Construction
[0023] (1) In the dynamic interactive network software structure, the more in-degrees any software Agent i has, the more times it is trusted, which means the higher the reputation and the better the prestige of this point, so other software Agents are more inclined to To trust it, it is easier to establish a trust relationship; in order to ensure the reliability of establishing a trust relationship, each software Agent that establishes a trust relationship with it will give feedback on the establishment of this trust relationship. The setting of the feedback function is as follows:
[0024] At time t, the number of trusted times in the trust information of software Agent i is T(t), and their feedback function is r k (t)(k=1, 2,..., T(t)), then The reputation of software Agent i is related to the feedback function value of related software Agent i in its trust information, and the defined feedback value is a feedback factor p i , then p i for: p ...

The invention discloses an trust negotiation constructing method for an internetware main body system under a dynamic interaction network environment, relates to a method for constructing automatic trust negotiation for an internetware main body system under a dynamic network environment and a structural situation, and provides an automatic trust negotiation method forthe internetware main body system suitable for a dynamic network interaction situation. The method is realized in such a way that each internetware main body owns the respective information i.e. trust and cooperation, and two main bodies requiring cooperation select the corresponding trust level and cooperation level (fitness) to establish the trust relationship according to the cooperation direction; whether the trust relationship is successfully established or not requires to be compared with the reference value, and the reference value is the calculation value based on the fitness when the main body in the system owns the average trust information; when the fitness is greater than the reference value, the trust relationship is established. The method avoids the trouble brought by using certificate, and the establishment of the trust relationship is simple and clear.
Description
technical field [0001] The invention relates to the construction of a method for automatic trust negotiation of a network-structured software Agent (main body) system in a dynamic network environment and a structured situation, and specifically relates to a method for establishing a trust mechanism using trust information of a software Agent in an interactive structure. Background technique [0002] Internet architecture software is a software system oriented to the open, dynamic, and changeable Internet (Internet) operating environment. This type of system is supported by software component technology and constructed through the interconnection, collaboration, and alliance of independent and open service entities. Internet-structured software systems usually include a large number of software subjects, and these software subjects cooperate with each other to complete tasks. During the running process, Internet-structured software Agent can make reasonable adaptive adjustmen...
