An Optimized Cryptography Algorithm And Key Exchange Method for Small Scale Devices

Geo Informatics team will port its current method of surveying which is on paper based on web based and mobile application. All this survey data are confidential for Government purpose. With the current revolution of smart devices, this paper exercise can be converted to digital experience, thereby reducing, analyzing time, increasing accuracy and this data should be secure. These systems require efficient and fast encryption algorithm because all data are confidential data and the data should not to be exposed. Various algorithms are already existing. As our system requirement symmetric algorithm is applicable. A number of symmetric key encryption algorithms like Vernam cipher, DES, 2 DES, AES, IDEA provide better security, but their execution speed is slow. These algorithms have their own security strength, execution speed and efficiency. The cryptography algorithm should be lightweight, fast execution and highly secure. In this study, the new security algorithm is proposed based on exiting symmetric key algorithm. This algorithm efficiency and execution speed will be better than other algorithms and security will be quite unbreakable. Integrity, confidentiality, authenticity, non-repudiation of data will also be ensured. DOI: 10.17762/ijritcc2321-8169.15052
