SOA have been deployed as a mean to offer a better flexibility, to increase efficiency through reuse of services and also to improve interoperability by providing new opportunities to connect heterogeneous platforms. However, those benefits make security more difficult to control. Fortunately, new standards are proposed to treat this issue, but their current use makes the architecture much more complex...
Service creation by composing existing services and/or network resources is considered by Telecom and Internet industries as the trend for service provisioning in next generation networks. Related research work is being carried out for years, and various service composition approaches have been proposed by different standardization organizations and companies catering to different network requirements...
Services participating in the composition are usually co-ordinated according to a workflow, composed by several activities, each of which carried out by a service. The binding of services to workflow activities may be affected by several parameters (e.g., QoS, price, reputation, etc.). In this paper, we propose a service binding driven by a further important requirement, that is, the incompatibilities...
When large data repositories are coupled with geographic distribution of data, users and systems, it is necessary to combine different technologies for implementing high-performance distributed knowledge discovery systems. On the other hand, computational grid is emerging as a very promising infrastructure for high-performance distributed computing. Grid applications such as astronomy, chemistry,...
Archive is a collection of historical records which have been accumulated over the course of an individual and institution's lifetime. Archive is considered as an invaluable asset which provides us with an insight into the lives and circumstances of past generations. In this paper, we describe the workflow model of an archival management system adopted by Macau Historical Archives. To further analyze...
A strong designated-verifier proxy signature scheme was proposed to protect the original signerpsilas interests. In this scheme, the verifier was designated by the original signer. The valid proxy signature generated by the proxy signer on behalf of the original signer can only be accepted by the designated verifier and no body else can be convinced about the proxy signaturespsila validity or invalidity...
Privacy-preserving data mining aims at securely extracting knowledge from two or more parties' private data. Secure multi-party computation is the paramount approach to it. In this paper, we study privacy-preserving add and multiply exchanging technology and present three new different approaches to privacy-preserving add to multiply protocol. After that, we analyze and compare the three different...
