From: An elliptic curve cryptosystem-based secure RFID mutual authentication for Internet of things in healthcare environment

Notation

Definition

\({T}_{H}\)

Hash computation time

\({T}_{E}\)

Elliptic curve polynomial computation time

\({T}_{PA}\)

Elliptic curve point addition computation time

\({T}_{PM}\)

Elliptic curve point multiplication computation time

\({T}_{PR}\)

Private key computation time

\({T}_{PU}\)

Public key computation time

  1. The Hash computation cost (\({T}_{H}\)) is much less than the private and public keys computation costs (\({T}_{PU}\) and \({T}_{PR}\))
