A Design and Analysis of Geo-Crypto Key Exchange Algorithm for Secure Transmission
L. Rama Parvathy, R. Logeshwari
The cryptography keys play important role in secure data transmission, whereas security key exchange between the sender and receiver is the challenging task. In general, keys which generated randomly are more difficult task to remember by the user. Also, storing the key even in secured place is not recommended due to advancement of hacking techniques. To avoid such issues, we propose the Geo-Crypto key exchange algorithm which works based on Diffie Hellman key exchange algorithm. This Diffie Hellman algorithm generates the public keys from the private information of both users which are shared to generate final symmetric Geo-Crypto key at the both ends. Also, the proposed system ensures the avoidance of feature template storage or cryptographic key, either in centralized database or a smart card.
