چکیده (انگلیسی):

The Hyper Text Transfer Protocol (HTTP) protocol plays a vital role in Web Services Security. Though the
HTTPs provide excellent security, they are not flexible enough to allow caches. HTTPi provides high integrity
and low security whereas HTTPs provide low integrity and high security. The goal of WS activity is to build
up set of technologies in order to direct WS to their complete prospective application. WS play an excellent
role, without which the internet applications cannot be made. To provide both high security and high integrity
in Web Services (WS), a new model is proposed. In this model, the combined HTTPs’s security and HTTPi’s
flexibility are considered to provide the best WS. In addition, the user affords the self encrypted data for
privacy preserving the requester agent. Finally, the requester agent encrypts the particular data so as to create
two protections known as self protection and agent protection. Due to mounting threats in the WS, numerous
developers and researchers attempt to enhance additional safekeeping in service level. When WS usages are
constantly increasing, it is necessary to give proper security as well as flexibility in WS. The requester agent
sends the data to the next level. In this message level, the header information can be self verified through
appropriate security mechanism proposed in the model. The results of this proposal are compared with the
existing methods and better performance is obtained by calculating the throughput and response time.
