A Comprehensive Survey of Identity-Based Key Management Techniques in Mobile Ad Hoc Networks (MANETs)

Cryptography forms a fundamental component of security mechanisms in mobile ad hoc networks (MANETs). Among various public key approaches, identity-based cryptographic techniques have gained significant attention for mobile environments because they simplify the key management process and reduce memory storage requirements. This paper presents an overview of existing identity-based key management schemes designed for MANETs. It also highlights several limitations and unresolved issues associated with these schemes, which remain insufficiently addressed and require further investigation in future research.
