Reducing Computational and Communication Complexity for Dynamic Provable Data Possession

Nowadays, an increasing number of persons choose to outsource their computing demands and storage demands to the Cloud. In order to ensure the integrity of the data in the untrusted Cloud, especially the dynamic files which can be updated online, we propose an improved dynamic provable data possession model. We use some homomorphic tags to verify the integrity of the file and use some hash values generated by some secret values and tags to prevent replay attack and forgery attack. Compared with previous works, our proposal reduces the computational and communication complexity from O(logn) to O(1). We did some experiments to ensure this improvement and extended the model to file sharing situation.

Blockchain-Based Light-Weighted Provable Data Possession for Low Performance Devices

Provable Data Possession(PDP)schemes have long been proposed to solve problem of how to check the integrity of data stored in cloud service without downloading.However,with the emerging of network consisting of low performance devices such as Internet of Things,we find that there are still two obstacles for applying PDP schemes.The first one is the heavy computation overhead in generating tags for data blocks,which is essential for setting up any PDP scheme.The other one is how to resist collusion attacks from third party auditors with any possible entities participating the auditing.In this paper,we propose a novel blockchain-based light-weighted PDP scheme for low performance devices,with an instance deployed on a cloud server.We design a secure outsourced tag generating method for low performance devices,which enables a kind of“hash-sign-switch”two-phase tag computing.With this method,users with low performance devices can employ third party auditors to compute modular exponential operations that accounts for the largest portion of computation overhead in tag generation,without leaking their data content.Chaincodes in blockchain network ensure the correctness of such outsourcing and prevent collusion attacks.The security analysis and performance evaluation prove that our scheme is both secure and efficient.

A Novel Provable Data Possession Scheme Based on Geographic Location Attribute

Increment of mobile cloud video motivates mobile users to utilize cloud storage service to address their demands, cloud storage provider always furnish a location-independent platform for managing user＇s data. However, mobile users wonder if their cloud video data leakage or dynamic migration to illegal service providers. In this paper, we design a novel provable data possession protocol based on data geographic location attribute, which allows data owner to auditing the integrity of their video data, which put forward an ideal choice for remote data possession checking in the mobile cloud storage. In our proposed scheme, we check out whether the video data dynamic migrate to an unspecified location （such as： overseas） by adding data geographic location attribute tag into provable data possession protocol. Moreover, we make sure the security of our proposed scheme under the Computational Diffic-Hellman assumption. The analysis and experiment results demonstrate that our proposed scheme is provably secure and efficient.

On the Reason of Changes of Chinese Possession Institution——from the Perspective of Historical Institutionalism

It is the important part of historical institutionalism to explore the reason of the changes of institutions,which includes key issues of historical institutionalism—why do institutions change?How do institutions play a new role through changing?As far as the reason of the changes is concerned,there are social reasons,economic reasons,technological reasons as well as concept reasons.Being part of the China’s civil law system,the possession institution unexceptionally experiences changing process of establishment,amendment,reform and innovation.This paper attempts to analyze the reason of the changes of the possession institution from the perspective of institutional change theory of the historical institutionalism,giving historical explanation of institutional changes and putting forward historical interpretation and support for the perfection of the contemporary possession institution.

Possessions Ceded for the Benefit of the Hospitals and Churches From the Sighisoara County

Transilvania is a province of the actual state of Romania, geographically situated in the middle of the country, in the inner arch of the Carpathians. Starting with the 10th century, the territory of Transilvania became attractive for the neighboring Hungarian royalty and later on, in the 1 lth century it was annexed into Hungary. For a better control of the newly annexed territory and in order to convert the orthodox population to Catholicism, the Hungarian rulers brought the Szeklers to Transilvania and two centuries later, German originating populations, from Rhine, Luxemburg, and Saxony （the name of Sas people, or Saxon of Transilvania derives from ＂Saxony＂）. The aim of this paper is to focus on the Sighisoara County, namely on the easement of certain areas for temporary or permanent maintenance or use by the church and hospitals in the region. That was a common practice in Medieval Europe aimed at ensuring the survival means for these institutions. However, it was not the only one to serve this goal. There were also donations on behalf of various people or allocations of money by the county authorities. The documents attesting this are unpublished, unedited and are to be found in the archives of the Brasov County, Budapest, and Vienna. They are the stepping stone of this paper and hence, they grant its originality. The objectives of the paper are to bring arguments in favor of the thesis that community money was directed towards meeting the needs of the hospitals, as well as towards supporting the widows, the orphans, and the needy ones. Worth noting in this respect is the management of the funds ceded to the church and county hospitals and that actually benefitted the whole community. Moreover, the paper also emphasizes the role played by education, since the latter is an important landmark for a community＇s development level
