Efficient Extended Chaotic Map-Based IBE for Industrial Environment [PDF]
IEEE Access, 2022 Identity-based encryption is a public key-based method of encryption that enables communicating identities to use some individual and unique information, such as their physical IP addresses and MAC addresses, to identify them and as public keys. The scheme does not require the extra device to store long-term public keys. So, it is convenient for use in
