Is the newly born quantum cryptography the ultimate solution for information security? A technique needs to be theoretically strong and also practically viable. But quantum cryptography comes to naught in the latter. We present here some of the quantum's theoretical weaknesses like lack of digital signatures (or any algorithm) along with its many real time implementation problems. We further pursue with the discussion about the potency of classical cryptography and its resplendent capabilities in providing security.

Horticulture is one of the most major human exercises everywhere. Brilliant horticulture incorporates a bunch of advances, gadgets, conventions and computational ideal models to improve farming cycles. Blockchain, Big information, man-made consciousness, cloud and edge processing give capacities and answers for keeping, storing and investigating the huge information created by parts. The entry of a yield from the maker to the purchaser is followed by a cultivating store network. A reasonable stage that grants association individuals to the ranch together is a blockchain-based cultivating store network. This technique dispenses with the necessity for a unified confided in power, go-betweens and business narratives, developing creation and security through supporting outrageous trustworthiness, obligation and wellbeing. In, Industry 4.0 is one of the smart manufacturing methods in various industrial fields. It's one to create the opportunity nowadays in mass production of the many industry fields.
