Revisiting the Database State Machine Approach
نویسندگان
چکیده
The Database State Machine (DBSM) is a replication mechanism for clusters of database servers. Read-only and update transactions are executed locally, but during commit, update transactions execution outcome is broadcast to all the servers for certification. The main DBSM’s weakness lies in its dependency on transaction readsets, needed for certification. This paper presents a technique to bypass the extraction and propagation of readsets. Our approach does not incur any communication overhead and still guarantees that transactions are serializable.

متن کاملA hybrid approach for database intrusion detection at transaction and inter-transaction levels
Nowadays, information plays an important role in organizations. Sensitive information is often stored in databases. Traditional mechanisms such as encryption, access control, and authentication cannot provide a high level of confidence. Therefore, the existence of Intrusion Detection Systems in databases is necessary. In this paper, we propose an intrusion detection system for detecting attacks...

متن کاملAn Effective Attack-Resilient Kalman Filter-Based Approach for Dynamic State Estimation of Synchronous Machine
Kalman filtering has been widely considered for dynamic state estimation in smart grids. Despite its unique merits, the Kalman Filter (KF)-based dynamic state estimation can be undesirably influenced by cyber adversarial attacks that can potentially be launched against the communication links in the Cyber-Physical System (CPS). To enhance the security of KF-based state estimation, in this paper...
متن کاملMODELING OF FLOW NUMBER OF ASPHALT MIXTURES USING A MULTI–KERNEL BASED SUPPORT VECTOR MACHINE APPROACH
Flow number of asphalt–aggregate mixtures as an explanatory factor has been proposed in order to assess the rutting potential of asphalt mixtures. This study proposes a multiple–kernel based support vector machine (MK–SVM) approach for modeling of flow number of asphalt mixtures. The MK–SVM approach consists of weighted least squares–support vector machine (WLS–SVM) integrating two kernel funct...
