Describing Service-Oriented Architecture （SOA） is critical in the development of Web based system, in this paper, an approach for describing SOA by extended Darwin is proposed. The requirements for describing SOA, which are different from that of ordinary architecture, are highlighted firstly, and then a solution for extending Darwin is presented. Using the extended Darwin, service components and connectors can be described explicit by the extended construct, as well as precise operational semantics of SOA by the π-calculus. Finally an example of supply-chain management system is given for manifesting the effect of the extended Darwin.

It is crucial for highly security-critical information systems to accurately control the disaster recovery activities. Using optimization theory, we present a disaster recovery planning mathematical model. The model uses mathematical method to express diverse entities in information and disaster recovery system such as applications, facilities, resources, sub disaster recovery plans, budget, etc. It classifies various resources according to their utilization and payment, and identifies the significance of applications and the conflicts among sub disaster recovery plans. Through expressing relationships among applications, facilities, resources and sub plans, this model selects the best set of sub plans. This model has less subjective parameter and can evaluate disaster recovery planning objectively and quantitatively.

We present a Robust Disaster Recovery System Model (RDRSM) for highly security-critical systems to realize continuous service. Through strengthening safe communication ability, RDRSM guarantees secure and reliable command on disaster recovery. It uses selfsupervision function to monitor the integrality and security of system itself. Through GIS, this model makes disaster recovery system easier to use, manage and maintain. RDRSM possesses features of security, robustness and controllability and can be applied to environments such as e-government and bank. This model successfully conducted the construction of an important e-government disaster recovery system, which verified its feasibility and the significance of its components, such as disaster recovery planning, system supervision and robust communication support.

Complicated information system (CIS) contains many inhomogeneous applications which require security, interoperability, extensibility. The paper presents a secure CIS architecture model to conduct the construction or reconstruction of CIS. Using layered method, it divides CIS into modules and reduces system complexity. Web service technology is widely adopted in layers to fulfill interoperability and extensibility. It uses encryption support layer, security protection and reliability support layer to guarantee system security and stability in different aspects. It uses system management layer to make CIS administrable. It suits highly security-critical environment such as government and bank. Been properly simplified, it can be applied to relative simple information system too.

In recent years, more and more people studied the Bayesian networks learning algorithm that integrates independence test with scoring metric. Based on the proposed hybrid algorithm I-B&B-MDL, a modified method is developed. There are two major contributions. Firstly, order-0 and partial order-1 independence tests are used to obtain an original graph of the network, which reduces the number of independence tests and database passes while effectively restricting the search space. Secondly, by means of the heuristic knowledge of mutual information, sort order for candidate parent nodes increases the cut-offs of the B&B search tree and accelerates search process. The experimental results show that the modified algorithm has high accuracy, and is more efficient in time complexity than other algorithms.

Cheng and Church algorithm is an important approach in biclustering algorithms. In this paper, the process of the extended space in the second stage of Cheng and Church algorithm is improved and the selections of two important parameters are discussed. The results of the improved algorithm used in the gene expression spectrum analysis show that, compared with Cheng and Church algorithm, the quality of clustering results is enhanced obviously, the mining expression models are better, and the data possess a strong consistency with fluctuation on the condition while the computational time does not increase significantly.

Ring authenticated encryption has the following security requirements: semantic-security, recipient-designation, verification-dependence, verification-convertibility, recipient-ambiguity, recipient-verifiability, signer-ambiguity and signer-verifiability. Ring authenticated encryption can be used to enhance user privacy. In this paper, based on Boneh and Frankliny's ID-based encryption scheme and Zhang and Kim's ID-based ring signature scheme, we propose an ID-based ring authenticated encryption scheme. We also show that the proposed scheme satisfies the correctness property and all security requirements.

To achieve interconnection environment, the proposed approach consists of MMFI for ontology and reference ontology for normalizing semantic space, ontology-induced schema mapping for transition from semantic interconnection to schema mapping, MMFI (ISO 19763) for normalizing interconnection environment, and a semantic matcher with schema mapping broker for dynamically clustering services or resources. In this case, while ontology helps identifying content of structural elements, a metamodeling architecture provides requisite structures for ontology representation. Our approach promotes fusing of ontology and metamodeling architecture and enhances interoperability in interconnection environment. This approach has been implemented in WHCRP prototype as a potential demonstration for MMFI. WHCRP aims to establish a R&R federation for sharing software components. Theoretical analysis and the prototype indicate the effectiveness of this approach.

Deniability is a privacy property that ensures protocol participants can later deny taking part in a particular protocol run. A deniable authentication protocol enables an intended receiver to identify the source of a given message, but not prove the identity of the sender to a third party even if the intended receiver is willing to reveal his secret-key. In this paper, we present an efficient ID-based deniable authentication protocol from pairings. The proposed protocol satisfies the correctness, authentication and deniability properties.

Cell's immunological information is acquired through analyzing color immunofluorescence image. A pixel growing algorithm with dynamic seed values is proposed to extract fluorescent regions in the CIE (L*, a*, b*) uniform color space. Ellipse matching method is proposed to extract cells from the obtained fluorescent regions. Finally antigen information is acquired through computing and decomposing color of the cell with the pre-computation and discretization method. The methods proposed for the acquirement of cell's immmunological information are appropriately evaluated. The experiment indicates that acquired the immunological information meets practical medicine analysis.
