TPTVer： A Trusted Third Party Based Trusted Verifier for Multi-Layered Outsourced Big Data System in Cloud Environment

Cloud computing is very useful for big data owner who doesn't want to manage IT infrastructure and big data technique details. However, it is hard for big data owner to trust multi-layer outsourced big data system in cloud environment and to verify which outsourced service leads to the problem. Similarly, the cloud service provider cannot simply trust the data computation applications. At last,the verification data itself may also leak the sensitive information from the cloud service provider and data owner. We propose a new three-level definition of the verification, threat model, corresponding trusted policies based on different roles for outsourced big data system in cloud. We also provide two policy enforcement methods for building trusted data computation environment by measuring both the Map Reduce application and its behaviors based on trusted computing and aspect-oriented programming. To prevent sensitive information leakage from verification process,we provide a privacy-preserved verification method. Finally, we implement the TPTVer, a Trusted third Party based Trusted Verifier as a proof of concept system. Our evaluation and analysis show that TPTVer can provide trusted verification for multi-layered outsourced big data system in the cloud with low overhead.

Secured Cloud Data Migration Technique by Competent Probabilistic Public Key Encryption

Cloud computing, a recently emerged paradigm faces major challenges in achieving the privacy of migrated data, network security, etc. Too many cryptographic technologies are raised to solve these issues based on identity, attributes and prediction algorithms yet;these techniques are highly prone to attackers. This would raise a need of an effective encryption technique, which would ensure secure data migration. With this scenario, our proposed methodology Efficient Probabilistic Public Key Encryption(EPPKE) is optimized with Covariance Matrix Adaptation Evolution Strategies(CMA-ES). It ensures data integrity through the Luhn algorithm with BLAKE 2b encapsulation. This enables an optimized security to the data which is migrated through cloud. The proposed methodology is implemented in Open Stack with Java Language. It achieves better results by providing security compared to other existing techniques like RSA, IBA, ABE, PBE, etc.

An Efficient Security Solution for Industrial Internet of Things Applications

The Industrial Internet of Things(IIoT)has been growing for presentations in industry in recent years.Security for the IIoT has unavoidably become a problem in terms of creating safe applications.Due to continual needs for new functionality,such as foresight,the number of linked devices in the industrial environment increases.Certification of fewer signatories gives strong authentication solutions and prevents trustworthy third parties from being publicly certified among available encryption instruments.Hence this blockchain-based endpoint protection platform(BCEPP)has been proposed to validate the network policies and reduce overall latency in isolation or hold endpoints.A resolver supports the encoded model as an input;network functions can be optimized as an output in an infrastructure network.The configuration of the virtual network functions(VNFs)involved fulfills network characteristics.The output ensures that the final service is supplied at the least cost,including processing time and network latency.According to the findings of this comparison,our design is better suited to simplified trust management in IIoT devices.Thus,the experimental results show the adaptability and resilience of our suggested confidence model against behavioral changes in hostile settings in IIoT networks.The experimental results show that our proposed method,BCEPP,has the following,when compared to other methods:high computational cost of 95.3%,low latency ratio of 28.5%,increased data transmitting rate up to 94.1%,enhanced security rate of 98.6%,packet reception ratio of 96.1%,user satisfaction index of 94.5%,and probability ratio of 33.8%.

Quantum Electronic Contract Scheme Based on Single Photon

An electronic contract is a contract signed by electronic means,which is widely used in electronic commerce activities.In recent years,with the rapid development of quantum cryptography technology,the quantum electronic contract has been widely studied by researchers.Supported by the basic principles of quantum mechanics,a quantum electronic contract scheme based on the single photon is proposed in this paper.In this scheme,two copies of the same contract are signed by both parties involved,and then a copy of each contract is sent to a trusted third party.The trusted third party verifies the signatures of both parties and compares the signed copies to determine whether the contract is valid.Compared with the previous scheme,this scheme is based on the quantum electronic contract signed by the single photon.Because the single photon is easy to prepare and operate,this scheme is simple and easy to implement.At the same time,the scheme does not need to exchange signatures between the two parties,which reduces the complexity of communication.Nevertheless,it requires both parties and the third party to be honest and trustworthy.

A Random Anonymity Framework for Location Privacy

Location k-anonymity techniques typically use anony- mous spatial region to ensure privacy. But these solutions are vul- nerable to multiple queries attacks and inference attacks. Failing to account for the obstacle in geographic space is a severe problem since adversaries will surely regard these constraints. A novel framework is proposed to enhance location-dependent queries, based on the theoretical work of k-anonymity and Voronoi diagrams, allows a user to express service requirement and privacy require- ment by specifying a region and an appropriate value ofk. A trusted anonymity server form a restricted set （k, r, s）, which is composed of a number of discrete points to meet the requirements for location k-anonymity and location /-diversity. The location-based services （LBS） server implements an efficient algorithm for continu- ous-region-query processing. Simulation results demonstrated that the framework is superior to previous works in terms of privacy. Moreover, discreteness and randomness of the anonymous set are conducive to resisting location tracking attacks.

Comments on the Chinese Law of Conflict of Laws Applicable to Trusts： In Comparison with the U.S. Law and the Hague Convention

China has entered a new era represented by the newly established China （Shanghai） Pilot Free Trade Zone, in which further reform and development of its financial system and capital market are highly prioritized. The trust as an important vehicle in development of the financial market in China as well as in the world will play an important role, and there will be more foreign elements involved in Chinese trusts. The Law of the People＇s Republic of China on Application of Laws in Civil Relations with Foreign Elements provides rules, in its article 17, on the application of laws to trusts, which symbolizes the formal creation of rules of conflict of laws in China in this area. However, it seems to cause more problems than it may resolve. For example, it may not always be possible for the parties to determine the appli- cable law through consultation and agreement, and the parties＇ right to choice of law should not be without limitation either. By allowing judges to choose from ＂the law of the situs where the trust property is situated＂ and ＂the law of the situs where the trust relationship occurred＂ in the absence of an effective choice of law by the parties may lead to a situation contrary to existing laws and may create uncertainty for the parties as well. This paper analyzes this article 17 by comparing it with the conflict law rules adopted in the United States and by the Hague Convention, identifies problems, and seeks to find solutions in order to promote the healthy development of the trust system in China.
