Key Management Using Certificateless Public Key Cryptography in Ad Hoc Networks [PDF]
, 2008 As various applications of wireless ad hoc network have been proposed, security has become one of the big research challenges and is receiving increasing attention. In this paper, we propose a distributed key management approach by using the recently developed concepts of certificateless public key cryptography and threshold secret sharing schemes ...

IET Information Security, Volume 2024, Issue 1, 2024.Named Data Networking (NDN) is a promising network architecture that differs from the traditional TCP/IP network, as it focuses on data rather than the host. A new secure model is required to provide the data‐oriented trust instead of the host‐oriented trust.

Functional Message Authentication Codes With Message and Function Privacy
IET Information Security, Volume 2024, Issue 1, 2024.Functional signatures were allowed anyone to sign any messages in the range of function f, who possesses the secret key skf. However, the existing construction does not satisfy the property of message and function privacy. In this paper, we propose a new notion which is called functional message authentication codes (MACs).

Malicious KGC Attack in Certificateless Cryptography
, 2006 Identity-based cryptosystems have an inherent key escrow issue, that is, the Key Generation Center (KGC) always knows user secret key. Thus, if the KGC is malicious, it can always impersonate the user.

A New Provably Secure Authentication and Key Agreement Mechanism for SIP Using Certificateless Public-key Cryptography 1 [PDF]
, 2007 . The session initiation protocol (SIP) is considered as the dominant signaling protocol for calls over the internet. However, SIP authentication typically uses HTTP digest authentication, which is vulnerable to many forms of known attacks.

Security-Mediated Certificateless Undeniable Signature Scheme
, 2018 Certificateless cryptosystems overcome the key escrow problem in identity-based cryptography. Mediated cryptography allows immediate revocation of public keys. Undeniable signatures limit the public verifiability of ordinary digital signatures.
