The Security Enhancement of Symmetric Key Crypto Mechanism based on Double Stage Secret Model

Abstract

ABSTRACT All smart services in cloud computing platforms have a data-sharing process to execute the task. Moreover, several crypto techniques were implemented to provide efficient and secure data transmission channel. However, it has been suffered with a number of issues because of several harmful attacks and unauthenticated key retrieval. Thus in the wireless medium, transferring the data amid two users are challengeable task. To overcome this issue, a novel Double-Stage Secret (DSS) cryptosystem is proposed to prevent the attacks in the communication channel, here the encryption and decryption function is processed based on some specific condition. If the DSS condition is satisfied then the client or user is requested to decrypt the message. To validate the secure and success rate of the proposed model, an efficient novel back sniff is developed and launched in the data transmission channel and its secure range is evaluated. In addition, the simulation of this research is done by Java, running on net beans IDE 8.2 in windows 10 platform and the results illustrated that the proposed model has attained high performance by gaining a high secure rate and less processing time of encryption and decryption than the existing algorithms.
