certain advantages of service-oriented architecture have led to the spread of this type of architecture around the world. however, some special features of this type of architecture have led to more compromise between the security in the information system and other information systems. the purpose of this paper is to identify and examine the impact of factors and dimensions of the information ...

quality of service (qos) is an important issue in the design and management of web service composition. qos in web services consists of various non-functional factors, such as execution cost, execution time, availability, successful execution rate, and security. in recent years, the number of available web services has proliferated, and then offered the same services increasingly. the same web ...

Quality of service (QoS) is an important issue in the design and management of web service composition. QoS in web services consists of various non-functional factors, such as execution cost, execution time, availability, successful execution rate, and security.

Web service is a distributed computing model constructed on the basis of open standard technology with the characteristics of loose coupling, language neutrality, platform-independence, etc., how to efficiently evaluate the security of Web service is a challenging research topic. Current researches concern more about the testing of Web service and rarely about the issue of service security eval...

Authentication is the process of making sure that the person who is requesting a web service is really the person that they claim to be. This is done by requiring the user to provide a set of credentials. In return, they will receive a security token that can be used to access the server. The credentials usually take the form of a user id and password. On the other hand, the security token that...

in this paper the design and implementation of fault tolerable architecture for scientific workflow engines is presented. the engines are assumed to be implemented as composite web services. current architectures for workflow engines do not make any considerations for substituting faulty web services with correct ones at run time. the difficulty is to rollback the execution state of the workflo...
