A New Provably Secure Authentication and Key Agreement Mechanism for SIP Using Certificateless Public-Key Cryptography [PDF]
Computer Communications, 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. This paper proposes a new secure authentication and key agreement mechanism based on certificateless public-key ...

Broadcast Proxy Reencryption Based on Certificateless Public Key Cryptography for Secure Data Sharing [PDF]
Wireless Communications and Mobile Computing, 2021 Broadcast proxy reencryption (BPRE), which combines broadcast encryption (BE) and proxy reencryption (PRE), is a technology used for the redistribution of data uploaded on the cloud to multiple users. BPRE reencrypts data encrypted by the distributor and then uploads it to the cloud into a ciphertext that at a later stage targets multiple recipients ...
