Abstract: The present invention relates to a highly flexible, scalable multi-blockchain, hierarchical data-sharing and data-storing system, at least comprising a third-party blockchain system, a data-sharing blockchain system, and an application-layer client, wherein the data-sharing blockchain system performs data aggregation and hierarchical storage on shared data uploaded by the third-party blockchain system through accessing the data-sharing blockchain system, so as to allow the application-layer client to require the shared data from the data-sharing blockchain system. The disclosure herein creates a single reliable data-sharing blockchain apparatus based on blockchain systems, so as to facilitate aggregation of data coming from different blockchain systems, reduce node complexity and block data redundancy when data are acquired from multiple parties, and define different sharing rules for different data contents, thereby being adaptive to scenarios where data are shared among parties.

Abstract: The present invention relates to a method and a system for robust, searchable, symmetrical encryption, the method comprising: during initialization, having a retrieval server perform retrieval on stored ciphertext information according to a searchable ciphertext and retrieval trapdoor information (Cntupd, K, Locgrp) sent by a client, wherein, the retrieval server acquires a last received first ciphertext set Cnew from a ciphertext database CDB just before the present retrieval according to a retrieval key K and an encryption counter Cntupd sent by the client, acquiring a second ciphertext set Ccache in a retrieval request history from a cache ciphertext database GRP according to a cache ciphertext index Locgrp, and merging the first ciphertext set Cnew and the second ciphertext set Ccache to form a retrieval set , and sending it to the client for decryption. The present invention is able to improve retrieval performance of searchable symmetrical encryption algorithm with robust forward and backward secrecy and to make searchable symmetrical encryption algorithm more practical.

Abstract: An S.M.A.R.T. threshold optimization method used for disk failure detection includes the steps of: analyzing S.M.A.R.T. attributes based on correlation between S.M.A.R.T. attribute information about plural failed and non-failed disks and failure information and sieving out weakly correlated attributes and/or strongly correlated attributes; and setting threshold intervals, multivariate thresholds and/or native thresholds corresponding to the S.M.A.R.T. attributes based on distribution patterns of the strongly or weakly correlated attributes. As compared to reactive fault tolerance, the disclosed method has no negative effects on reading and writing performance of disks and performance of storage systems as a whole. As compared to the known methods that use native disk S.M.A.R.T. thresholds, the disclosed method significantly improves disk failure detection rate with a low false alarm rate. As compared to disk failure forecast based on machine learning algorithm, the disclosed method has good interpretability and allows easy adjustment of its forecast performance.

Abstract: The present invention discloses a container-based mobile code offloading support system in a cloud environment and the offloading method thereof, comprising a front-end processing layer, a runtime layer and a back-end resource layer. The front-end processing layer is responsible for responding to an arrived request and managing a status of a container, which is realized by a request distribution module, a code caching module and a monitoring and scheduling module; the runtime layer provides the same execution environment as that of a terminal, which is realized by a runtime module consisted of a plurality of mobile cloud containers; and the back-end resource layer solves incompatibility of a cloud platform with an mobile terminal environment and provides underlying resource support for a runtime, which is realized by a resource sharing module and an extended kernel module within a host operating system. The present invention utilizes the built mobile cloud container as the runtime environment for offloading code, ensuring execution requirements of offloading tasks and improving the computing performance of a cloud; cooperation between respective modules makes a further optimization to the performance of the platform, guaranteeing an efficient operation for the system.
