  In Cloud Computing Architecture, Brokers are responsible to provide services
to the end users. An Effective Cost Management System (ECMS) which works over
Secure Cloud Communication Paradigm (SCCP) helps in finding a communication
link with overall minimum cost of links. We propose an improved Broker Cloud
Communication Paradigm (BCCP) with integration of security issues. Two
algorithms are included, first is Secure Optimized Route Cost Finder (S-ORCF)
to find optimum route between broker and cloud on the behalf of cost factor and
second is Secure Optimized Route Management (S-ORM) to maintain optimum route.
These algorithms proposed with cryptographic integrity of the secure route
discovery process in efficient routing approaches between broker and cloud.
There is lack in Dynamic Source Routing Approach to verify whether any
intermediate node has been deleted, inserted or modified with no valid
authentication. We use symmetric cryptographic primitives, which is made
possible due to multisource broadcast encryption scheme. This paper outlines
the use of secure route discovery protocol (SRDP)that employs such a security
paradigm in cloud computing.
