Comparison and Analysis of Cryptographic Algorithms Aiming Performance Improvement in Secure Web Services

In this paper is shown an evaluation and comparison of techniques that allow the validation of the Web services used, to determine characteristics related to performance and security. In this sense, it is crucial evaluate the cryptography and digital signature performance in SOAP messages, performing the change of cryptographic algorithms, as well as the keys length. Security at the message-level was provided using WSSecurity. The results obtained allow to determine the impact of security mechanisms used in this type of applications.
