Current players and emerging players are looking for new retail format. The current attractive pattern is Electronic retailing which is on a fast progress development. Internet access to the customer's changing and huge process is developing and also the peddlers take note and consumer right to make your design and traditional value approach you need to make. All the above increase of current attempts to paper: E-commerce retail business's current description of tilt-in Indian conditions and services and discussed the worldwide electronic commerce current inclination. Describe Indian conditions electronic retail sales in regards to customers at the time of purchase due to their attitude. Research Design: Gathered secondary data for research study for the purposes of e-commerce in retail business products and servic...

This fraud can be minimized if there is a tamper-proof and confidential registry of certificates wherein not one but multiple certified authorities verifies and stores the issued certificate in immutable repositories with proper privacy maintained. Secondly, there should be a mechanism for retrieving the authentic certificate without much cost and time. Blockchain is an immutable, shared, distributed ledger without the control of a single centralized authority that fits very well for the discussed use case. The proposed work, PrivateCertChain, has implemented the idea for university having multiple affiliated colleges, by deploying and verifying digitally signed e-certificate on Ethereum Blockchain. Multiple affiliated colleges can serve as the miners for verifying the signature of the issuer. For privacy concerns, the content of the certificate will be hashed and this hashed value will be s...

Good amount of research is initiated for resource provisioning on hypervisors, still many issues need to be addressed for security demanding and real time VMs. First work SRT-CreditScheduler (Secured and Real-time), maximizes the success rate by dynamically prioritizing the urgency and the workload of VMs but ensures highest security for all. Another work, SA-RT-CreditScheduler (Security-aware and Real-time) is a dual objective scheduler, which maximizes the success rate of VMs in best possible security range as specified by the VM owner. Though the algorithms can be used by any hypervisor, for the current work they have been implemented on Xen hypervisor. Their effectiveness is validated by comparing it with Xen's, Credit and SEDF scheduler...

Applications with stringent security requirement introduce challenging concerns when executed on the grid resources. Though grid scheduler considers the computational heterogeneity while making scheduling decisions, little is done to address their security heterogeneity. This work proposes a security aware computational grid scheduling model, which schedules the tasks taking into account both kinds of heterogeneities. The approach is known as Security Prioritized MinMin (SPMinMin). Comparing it with one of the widely used grid scheduling algorithm, MinMin (secured) shows that SPMinMin performs better and sometimes behaves similar to MinMin under all possible situations in terms of makespan and system utilization.

Virtualization architecture provides this illusion through hyper visors/Virtual Machine Monitor, which maps the physical resource to Virtual machines. Security is very essential for cloud users as they relinquish physical possession of their computation and data, which inevitably poses new security risks towards the confidentiality and integrity of the data. Lot of research is initiated in resource provisioning for hyper visors, but still many problems need to be addressed specially for security-aware and real time tasks. A dual objective scheduling algorithm, Real Time Security Maximization (RT-Smax), which aims to meet the deadline of the Virtual machines with best possible security is being proposed. Though this algorithm can be used by any hyper visor, for the current work it has been implemented on Xen VMM. Finally its effectiveness is validated by comparing it with Xen's credit scheduler on security demanding tasks having stringent deadline constraints.
