Secure Data Communication using Cryptography

This report is to investigate the effects of process variables on the solid gain, water loss using the Response surface methodology (RSM). The ginger was Osmo-dehydrated using process variables such has blanching time, the temperature for an osmotic solution, immersion, & convective drying temperature .response variables tested were solid gain and water loss. The blanching is done to inactivate the enzyme and to increase permeability in ginger candy. The optimum Osmo-convective process conditions for a maximum solid gain, water loss, and overall acceptability of honey-ginger candy were 8.39 min blanching time, 39˚Csolution temperature, 94 min immersion time, and 70˚C convective drying temperature. Keywords: Osmo-dehydration, optimization, honey ginger candy, RSMAxAny type of digital information is called as data. In today's world, precarious data are growing and used in communication over internet. Hence, data security is most important factor for the internet users. The best solution is to use some cryptography algorithms which encrypts data in some cipher and transmit it over the internet and again decrypted to genuine data. Cryptography is eternal. The field of cryptography manages the technique for passing on information safely. The objective is to permit the expected recipients to get the message appropriately while interfere with snoopers from understanding the message. Key arrangement layout allows communicating parties to establish a mutual cipher key. The situation of present day of data security framework incorporates secrecy, legitimacy, trustworthiness, non-repudiation. This paper introduces a improved system for securing text-data communication benefiting the use of RSA algorithm. It is the public-key cryptosystem and is mainly used for secure data transmission[1].
