RBAC96, which is the most famous family of RBAC models, provides a common frame reference for related research and development. Many properties proposed in the family, e.g. limited inheritance, mutually exclusive roles, cardinality, and interaction, have been separately discussed in the previous work. In this paper, an extended RBAC model implementing those properties is proposed to provide an approach for implementing RBAC3. The extended RBAC model is based on deputy mechanism and is called deputy-based access control (DBAC). Since the private role hierarchy and constraint can be uniformly handled in DBAC, a flexible and powerful access control system can be implemented.","PeriodicalId":144075,"journal":{"name":"2008 International Symposium on Electronic Commerce and Security","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126960149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A weighted sum is prevalent in trust formalization. Trust is contextual, continuous and changeful. There are many factors that can affect trust update in the whole lifetime of trust. However, these factors have not been studied thoroughly. In this paper, we propose a weighted trust formula and present an integrated trust update method. First, we will compare several recommendation trust formula and analyze the factors that affect trust update. We propose to use abnormal trust value sequence and statistical analysis to detect malicious recommenders and false recommendation trust values in the whole lifetime of trust. Assuming that direct trust weight and recommendation trust weight are independent from each other, we propose a real-time weight update method through trust value sequences. Simulation results show that our method could effectively detect malicious recommenders and malicious recommendation trust values and make trust value sequence smoother.","PeriodicalId":144075,"journal":{"name":"2008 International Symposium on Electronic Commerce and Security","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122025037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes a program file authorization model based on an integrity measurement and access control combined methodology. It measures integrity signature of each program file and verifies it with the its original value before its execution. By allowing only running of known and trusted programs, it is able to disable invokes of malicious programs. To protect from attacks which donpsilat modify a program file, an active code authorization scheme is proposed. It divides a program file into an ordered series of code blocks by the return and jump instructions, constructs the integrity signatures of all code blocks respectively at compiling time, then measures and verifies them at run-time. By disallowing unexpected code blocks from running, it is able to prevent invokes of malicious codes injected by attackers.","PeriodicalId":144075,"journal":{"name":"2008 International Symposium on Electronic Commerce and Security","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125925510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, retrieving the knowledge of the opponent to simulate the opponentpsilas possible actions can increase the payoffs. An ANN_based Opponentpsilas negotiation behavior model (OpNBM) is proposed. It consists of two basic negotiation behaviors: Bid_Evaluation simulates the negotiatorpsilas utility function, and Bid_Generation simulates the concession strategy. Furthermore, by observing the changes of the opponent during the actual bargaining process, the agent keeps adjusting the OpNBM with increase of the negotiation rounds. Several experiments have shown that the OpNBM can help agents to better prepare for the negotiation and achieve a better outcome.","PeriodicalId":144075,"journal":{"name":"2008 International Symposium on Electronic Commerce and Security","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128984157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
