Key Agreement Protocols Clause Samples

Key Agreement Protocols. The ▇▇▇▇▇▇-▇▇▇▇▇▇▇ protocol is the first public-key agreement protocol [24]. But this protocol lacks the authentication of communication entities, and it cannot resist the hacking attack, which has abilities to control the communication channel [25]. Authenticated KA protocols can resist attacks from active adversaries in the traditional public-key cryptosystem. However, there appeared to be a new problem with certificate management for those KA protocols under the traditional public- key cryptosystem. Then, to simplify the key management, ▇▇▇▇▇▇ first gave the idea of public-key cryptography with personal identity, which was called ID-PKC [26]. There existed a key generation centre (KGC) which served as the trusted third party to generate the private key relating to the user’s identity, and the identity was the user’s public key. Although ID-PKC can efficiently solve the problem of certificate management, it can also suffer attacks from the KGC, which possesses all the user’s secret keys. The malicious KGC can simulate any user to deceive others, which is known as the private key escrow problem [27]. In addition, certificateless public key cryptography (CL-PKC) has been introduced to weaken the influence of the key escrow problem in ID-PKC [28]. Some CL-PKC-based KA protocols have been presented in recent years. ▇▇▇▇▇ proposed a modified certificateless pairing-based KA protocol with formal security analysis, which only needed to transmit the message one time between two parties [29]. Islam et al. proposed a certificateless multi- receiver encryption-based elliptic curve cryptography without bilinear pairings [30]. ▇▇▇▇ et al. sum- marized the impersonation attacks on the certificateless KA protocol and introduced some possible solutions [31]. ▇▇▇ et al. gave a certificateless authenticated KA protocol based on the ▇▇▇▇▇▇-▇▇▇▇▇▇▇ assumption [32]. Meanwhile, ▇▇▇▇▇▇▇▇ et al. presented a certificateless KA protocol, claiming this scheme is lightweight for IoT communication [33]. ▇▇▇▇ et al. proposed a two-party certificateless authenticated KA for a smart grid [34]. ▇▇▇▇▇▇▇▇ et al. introduced a lightweight authentication scheme with KA protocol to improve the security of patient privacy in IoMT [35]. ▇▇▇▇▇▇▇▇▇ et al. proposed a secure KA scheme for a UAV-based crowd monitoring system [36]. Pu et al. introduced a KA protocol for wireless body area networks, which satisfied the properties of lightweight and anonymity [37]. These protocols have strong applicati...
