As more and more services are offered in clouds, it is possible to meet the diverse demands of users via service composition. Selecting the optimal set of services, in terms of QoS, is the crucial issue when many functionally equivalent services are available. In this paper, we investigate the service selection problem under the service replica limitation constraint. The objective is to select the...
The paper proposes a multi-agent assistant model (MAaDRMM/) to provide a combination QoS management of the composite service in SOA environment. The paper first introduced the QoS model of service resources and its mathematical definitions and then provide MAaDRMM to manage both the relationship between the resources and the runtime status of each resource. When the structure of the workflow is modified...
The primary goal of the secure socket layer protocol (SSL) is to provide confidentiality and data integrity between two communicating entities. Since the most computationally expensive step in the SSL handshake protocol is the server's RSA decryption, it is introduced that the proposed secret exchange algorithm can be used to speedup SSL session initialization. The optimization strategy, which is...
