The wide spread of click-and-mortar model offers an opportunity to consider a universal commercial interaction method. However, issues like privacy protection resist the widespread acceptance. Traditional SET and SSL protocols are designed using Public Key Infrastructure (PKI) where extensive computations are carried out. Our aim is here to design a protocol to secure any type of commercial interaction for online platform, which also considers mobile platform. Therefore, our focus is on reducing heavy computations and making the overall procedure faster. A Secured Click and Mortar Commercial Interaction (SCMCI) protocol is proposed here to improve the performance of the commercial interaction procedure through replacing time consuming public key encryption and decryption algorithms by hybrid logic including the use of symmetric key. Comparative analysis has been done with traditional SET protocol using cryptool to prove the efficiency of the protocol.

Internet of Things is a novel concept that semantically implies a world-wide network of uniquely addressable interconnected smart objects. It is aimed at establishing any paradigm in computing. This environment is one where the boundary between virtual and physical world is eliminated. As the network gets loaded with hitherto unknown applications, security threats also become rampant. Current security solutions fail as new threats appear to de-struct the reliability of information. The network has to be transformed to IPv6 enabled network to address huge number of smart objects. Thus new addressing schemes come up with new attacks. Real time analysis of information from the heterogeneous smart objects needs use of cloud services. This can fall prey to cloud specific security threats. Therefore need arises for a review of security threats for a new area having huge demand. Here a study of security issues in this domain is briefly presented.
