Table 1

Description of existing work.

Ref	Year	Proposed scheme	Strength	Weakness
[9]	2017	Lightweight cryptography scheme considering both ECC and ElGamal	ECC for key generation and ElGamal for encryption/decryption of messages	High overhead
[10]	2019	Lightweight authentication technique based on ElGamal encryption	Use a mix of ECC for key pair selection and ElGamal encryption for secret key exchange	No lightweight symmetric encryption
[11]	2019	Authentication technique uses certificateless cryptography	D2D authentication technique	Asymmetric encryption with high overhead
[12]	2020	Authentication mechanism along with device detection and privacy protection with the use of identity-based encryption	Authentication, privacy protection	Weak encryption mechanism
[13]	2021	Lightweight multilayer authentication scheme	ECC algorithm with low computation cost	No lightweight symmetric encryption
Proposed work	2022	Security mechanism in 5G network for D2D wireless communication dependent on lightweight modified elliptic curve cryptography (LMECC)	Lightweight symmetric encryption with low protocol overhead	More focused on 5G D2D communication with/without various security challenges
