MTBAC： A Mutual Trust Based Access Control Model in Cloud Computing

As a new computing mode,cloud computing can provide users with virtualized and scalable web services,which faced with serious security challenges,however.Access control is one of the most important measures to ensure the security of cloud computing.But applying traditional access control model into the Cloud directly could not solve the uncertainty and vulnerability caused by the open conditions of cloud computing.In cloud computing environment,only when the security and reliability of both interaction parties are ensured,data security can be effectively guaranteed during interactions between users and the Cloud.Therefore,building a mutual trust relationship between users and cloud platform is the key to implement new kinds of access control method in cloud computing environment.Combining with Trust Management(TM),a mutual trust based access control(MTBAC) model is proposed in this paper.MTBAC model take both user's behavior trust and cloud services node's credibility into consideration.Trust relationships between users and cloud service nodes are established by mutual trust mechanism.Security problems of access control are solved by implementing MTBAC model into cloud computing environment.Simulation experiments show that MTBAC model can guarantee the interaction between users and cloud service nodes.

Mutual Trust—Key to Sino-Japanese Amity

Drift marked China-Japan ties in most part of the 1990s, accompanied with wild swings. The last decade of the 20th century witnessed the commemoration of the 20th anniversary(1972-1992)of diplomatic normalization, the 50th anniversary(1945-1995)of the victory of the War of Resistance Against Japanese Aggression, the furor over the "No War decision" in Japan, and the shock waves from the reorientation of Japan-U.

China and the United States： Mutual Trust

China and the United States are considered to be the most important bilateral relations in the world, and they are also the most complex one in the world. Competition, prevention and cooperation, mutual trust and mutual mapping out a different side is the current state of Sino-US relations. How to protect the mechanism of the accident but not an accident drag？ How to ensure that both China and the United States have a minimum of judgment of each other＇s major military strategic intentions and the direction of a major national strategy？ Sino-US relations and mutual trust will not lead to hostile nations. When faced with inevitable differences and competition, how can China and the United States establish an effective mutual trust to avoid conflict？

Strategic Mutual Trust from the Perspective of Spatial Blending

As global, regional, national, local and other spatial forms become mutually embedded and interwoven, a new anti-globalization force is shaping a ＂reverse globalization trend＂ in an attempt to go beyond the integrated ＂capital-production-market＂ model established in the previous globalization era. Amid continuous social change, economic space has seen a reassertion of trade protectionism, while political space is facing the rise of populist parties. Britain＇s exit from European Union has dealt a heavy blow to the process of European integration, once again empowering national and local levels through traditional sentiments and redefining the international order in the new era of globalization. In this new era, as global economic integration slows down, the Chinese plan of the Belt and Road Initiative focuses on building a ＂community of shared future for mankind,＂ ＂with unwavering efforts to advance and guide economic globalization trends.＂ Its open and inclusive strategic content; its strategic orientation of mutual learning; and its strategic aim of development and coexistence on an economic basis under political intermediation and through the guidance of culture highlight the integration of economic space, mutual trust in political space, and inclusiveness incultural space. The spatial extension of the strategic mutual trust of the Belt and Road Initiative originates in rational reflection on fundamental emotional expectations; instrumental sharing of benefit; emotional involvement; and value judgments. Based on the fact that the population along its route are recipients of the values of strategic mutual trust and also makers of its meanings, we can divide the promotion of the Belt and Road Initiative into cultural resonance zones, zones that activate the interests of different parties, and zones that promote identification, combining regional nodes and cooperative content. In order to enhance the degree of congruence of strategic mutual trust, we should disseminate these values in a way that combines charm, comprehensiveness and accuracy.

Multilateralism and the Realization of the Chinese Dream： A Possible Way to Nurture Mutual Trust

When China＇s new president Xi Jinping first introduced the Chinese dream, he said that Chinese dream means the great revival of the Chinese nation （中华民族伟大复兴） （Xinhua Net： http：//news.xinhuanet.com/ziliao/2013-05108/c_ 124669102.htm）. This great revival invites people to refer to the most prosperous time of Chinese history, when China had been the greatest nation in the world both economically and militarily. Mr. Wang Yi, the new minister of foreign affairs, has explained that the realization of Chinese dreams, albeit the great revival of the Chinese nation needs a peaceful and stable neighborhood （Wang Yi： Insist on Peaceful Development, Realise the Chinese Dream of Nation＇s Revival： http：// theory.people.com.cn/n/2014/0217/c40531-24378766.html）. Yet now the most prominent threat, as China＇s military and economic powers quickly rise, is the deficiency in trust toward China. This lack of mutual trust is especially important among East Asian countries （Ba and Shen in Jilin Univ J Soc Sci Edit 54（3）： 13-20, 2014, p. 14）, the most direct neighborhood of China. In the article, I will analyze the historical and political origins of mistrust toward China, and argue that multilateralism is a highly possible solution for the problem of trust deficiency. Thus, adopting multilateralism is the key for realizing Chinese dreams, because it generates trusts by regulating states＇ behavior through institutionalization of collaboration.

METrust: A Mutual Evaluation-based Trust Model for P2P Networks

It is necessary to construct an effective trust model to build trust relationship between peers in peer-to-peer （P2P） network and enhance the security and reliability of P2P systems. The current trust models only focus on the consumers＇ evaluation to a transaction, which may be abused by malicious peers to exaggerate or slander the provider deliberately. In this paper, we propose a novel trust model based on mutual evaluation, called METrust, to suppress the peers＇ malicious behavior, such as dishonest evaluation and strategic attack. METrust considers the factors including mutual evaluation, similarity risk, time window, incentive, and punishment mechanism. The trust value is composed of the direct trust value and the recommendation trust value. In order to inhibit dishonest evaluation, both participants should give evaluation information based on peers＇ own experiences about the transaction while computing the direct trust value. In view of this, the mutual evaluation consistency factor and its time decay function are proposed. Besides, to reduce the risk of computing the recommendation trust based on the recommendations of friend peers, the similarity risk is introduced to measure the uncertainty of the similarity computing, while similarity is used to measure credibility. The experimental results show that METrust is effective, and it has advantages in the inhibition of the various malicious behaviors.
