Scalable, efficient, and secure RFID with elliptic curve cryptosystem for Internet of Things in healthcare environment

EURASIP Journal on Information Security

Table 3 Definition of some notations used in performance evaluation of the proposed scheme

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

Note: We should be aware that the hash computation cost (T_H) is much less than the private and public keys computation costs (T_PU and T_PR)
