Evolution of technology has completely revolutionaries’ day to day life of common man. Technology has penetrated in our life like anything. These days everybody is using technology for their benefit’s and marketers are no an exception to it. They are using technology to reach to the customers. Days are far gone when people used to line up in stores to purchase the general product. These days, more and more individuals lean toward online shopping, which is presently a pattern of style and fashion. Nagpur, the center city of the country and world-famous for its oranges is advancing towards computerized explosion that makes high significance on the assessment of the present acknowledgment level of online shopping by the youngsters. In this way, understanding the by and a large state of customer's attitude towards web-based shopping is significant for the Nagpurians. In this study, 143 respondents took part in the survey. Respondents were selected through simple random technique. Data was analyzed using SPSS Version 22. This study found that online shopping is very common in this young generation of Nagpur. Major reason for Nagpurains to do online shopping is that it saves a lot of time. However, consumer those who do not shop online is only because of online fraud, lack of personal touch and no return policy. Nagpur consumers do prescribe online shopping as an elective path for shopping.

AbstractRecently, cryptographic literature has seen new block cipher designs such as , or that aim to be more lightweight than the current standard, i.e., . Even though family of block ciphers were designed two decades ago, they still remain as the de facto encryption standard, with being the most widely deployed variant. In this work, we revisit the combined one-in-all implementation of the family, namely both encryption and decryption of each as a single ASIC circuit. A preliminary version appeared in Africacrypt 2019 by Balli and Banik, where the authors design a byte-serial circuit with such functionality. We improve on their work by reducing the size of the compact circuit to 2268 GE through 1-bit-serial implementation, which achieves 38% reduction in area. We also report stand-alone bit-serial versions of the circuit, targeting only a subset of modes and versions, e.g., and . Our results imply that, in terms of area, and can easily compete with the larger members of recently designed family, e.g., , . Thus, our implementations can be used interchangeably inside authenticated encryption candidates such as , or in place of .
