Analysis of Security Problems in Services Computing

Services computing is a new computing model and the development direction of the next generation of distributed computing,and due to the different understanding of services computing among different companies or individuals,there is no generally accepted definition of it now.With the rapid development of services computing in recent years,services available on the internet increase sharply,and at the same time,new issues especially the security problems come out.And the security problems become a very important factor which affects and restricts services computing application.First,it described basic concepts and supporting technologies of services computing.Then,analyzed mainly security problems which are faced by services computing,and finally,pointed the next step of research.
