ABSTRACT

The “intelligent adaptive participant’s presumption protocol” (iAP3 ) is an integrated atomic commit protocol. It interoperates implicit yes-vote, which is a one-phase commit protocol, besides presumed abort and presumed commit, the most commonly pronounced two-phase commit protocol variants. The aim of this combination is to achieve the performance advantages of one-phase commit protocols, on one hand, and the wide applicability of two-phase commit protocols, on the other. iAP3 interoperates the three protocols in a dynamic fashion and on a per participant basis, in spite of the incompatibilities among the three protocols. Besides that, the protocol is backward compatible with the standardized presumed abort protocol. Whereas iAP3 was initially proposed for the two-level (or flat) transaction execution model, this article extends the protocol to the multi-level distributed transaction execution model, the model adopted by the database standards and widely implemented in commercial database systems. Thus, broadening the applicability scope of the iAP3 .

  HYBRID ENCRYPTION ALGORITHMS FOR MEDICAL DATA STORAGE SECURITY IN CLOUD DATABASE Fenghua Zhang1，Yaming Chen2，Weiming Meng3 and Qingtao Wu4 1Computer Technology, Henan University of Science and Technology, Luo Yang, China 2,3Computer Science and Technology, Henan University of Science and Technology, Luo Yang, China 4Professor, Henan University of Science and Technology, Luo Yang, China ABSTRACT Cloud database are derivatives of Cloud computing. At present, most medical institutions store data in cloud database. Although the cloud database improves the efficiency of use, it also poses a huge impact and challenge to the secure storage of data. The article proposes a hybrid algorithm to solve the data security problem in the hospital cloud database. First, the AES algorithm is improved. The improved algorithm is called P-AES algorithm. The P-AES algorithm is then combined with the RSA algorithm, called a hybrid algorithm. The experimental results show that the hybrid enc...
