TPHC : Implementation of 3 phase hybrid cryptographic technique for energy conservation in WSN

We are becoming more digitalized in these days because of advancements in technology and we know that every advancements come with certain risks. We use internet in our daily life for online payment, transfer of our credentials, and many more, but we are not aware of the risks until we face them. Cryptography plays a vital role in protecting our secret information over the internet. In this paper, we have designed a hybrid algorithm that uses three cryptography algorithms, i.e, AES, DES and modified RSA. We compared our work with others’ work in terms of number of packets sent to base station and sum of energy of remaining nodes. Subject Classification: 68P25, 94A60.
