Web services have generated great interests in researchers recently due to its heterogeneous nature. These are based on existing Internet protocols and open standards. It can provide a flexible solution to the problem of application integration. These can be combined together through service composition to solve critical problems, which exists in current scenarios . The service composition suffers from several limitations of security issues such as lack of native support for encryption, decryption and authorization . In this paper, we have proposed a generalized framework for secure web service composition, which incorporates cryptography techniques. The current scenario get benefited by secure environment over network, prevent unauthorized access of services and support of encryption and decryption mechanism in terms of service composition with the help of proposed framework.
