Research On Efficient Automated Trust Negotiation Algorithm And Protocol For Mobile Business Environment

Automated trust negotiation as a stranger across the security domain is an effective way to build trust between entities. It is one of the hot issue in research of trust management. In recent years, the rise of mobile commerce and the rapid development caused the extensive concern of the industry, however, mobile commerce security issues still exist many difficulties in the theory and practice, mobile environment of trust negotiation research is particularly important. As the main line for further research in this paper.According to the existing theory of trust negotiation research, this paper first puts forward the sequence prediction algorithm based on the molecular sequence of negotiation. Molecular sequence refers to the historical sequence fragment through consultation. In trust negotiation sequence generation phase, when the negotiation success, both parties to establish a complete sequence of trust negotiation; When negotiation is not successful, even though both parties ultimately unable to generate a complete sequence of negotiation, but may agree part of information consultation, namely, to establish a negotiation sequence fragment. Make the fullest use of these historical negotiations can accelerate the trust negotiation sequences generated. So molecular series forecasting is put forward to accelerate the establishment of the negotiations both sides trust. Mobile commerce, the consumer decision whether or not some sort of deal, according to the current trading and has certain transactions that have occurred in the similarity, the historical negotiate sequence fragment restructuring, through forecasting directly generate trust negotiation sequence, without having to perform negotiation strategy algorithm, simplifies the process of trust negotiation. If negotiation sequence forecast failure, due to the flexibility of molecular sequences, can still will be introduced to the molecular sequence prediction during the execution of the various negotiation strategy algorithm, improve the efficiency of negotiation strategy algorithm.Most of the existing consultation agreement did not consider trust certificate validation computational overhead, based on this the paper fourth chapter puts forward automated trust negotiation protocol based on trading instruments. In traditional negotiation strategy interaction process, the two sides according to their respective access control policy negotiation, when the access control policy is more complex, the negotiation process is complex, and automated trust negotiation protocol based on trading instruments based on first trading instruments to evaluate each other’s trust, and dynamic adjustment of access control policy based on trust. In trust certificate exchange phase, negotiators may, according to trading instruments and the number of warrants reduce trust certificate authentication, thus completing the process of negotiation.
