WORKFLOW SIGNATURES FOR SECURE E-BUSINESS PROCESS

In the existing system, root authority generates business workflow plan and then signature to the business workflow is generated. Each authorized person checks workflow plan activities using signature verification algorithm. Each node verification is not validated in the existing approach. Any one who breaks the signature using exiting rsa approach can change the business workflow. So in order to overcome this part in the proposed work we generate policy to each authorized persons and the each node in the business workflow signature is generated so that this framework provides more security compare to existing approach. This system takes less time when compare to existing approach. In this paper, we propose a concrete workflow signature scheme, which is based on Elliptic curve cryptography; to meet security properties required by inter organizational workflows. After that signature is generated to each node .Time takes to generate signature to each node is linear complexity when compare to exiting quadratic complexity
