Cryptographic key communication protocol using elliptic curve over finite field with nested construction of hash message authentication code
(International Journal of Advanced Research in Computer Science, 2018) Suneetha, Ch.; Sravana Kumar, D.; Sirisha, P.
As the internet is the basic means of communication nowadays confirming the integrity and authenticity of the received data is a prime necessity in communication network. The present paper explores the key communication protocol from one entity to the other rather than sharing the part of the key by both the entities using elliptic curve over finite field. In addition one Nested construction of Hash Message Authentication Code (NMAC) is tagged to the communicated key that guards the communicated key for verification using cartographic hash function. The protocol designed here is more suitable for communicating high secured pass words and PIN numbers in monetary transactions
