Certificateless Public Key Cryptography in the Standard Model

Fundamenta Informaticae, 2018
Identity-based cryptography has been introduced by Shamir at Crypto’84 to avoid the use of expensive certificates in certified public key cryptography. In such system, the identity becomes the public key and each user needs to interact with a designated authority to obtain the related private key.

A Method for Fast Revocation of Certificateless Public Key Cryptography

2006 International Conference on Computer Engineering and Systems, 2006
"Certificateless Public Key Cryptography" has very appealing features, namely it does not require any public key certification (traditional Public Key Cryptography) nor having key escrow problem (Identity-Based Cryptography). Unfortunately, construction of Certificateless Public Key Encryption (CLPKE) schemes has so far depended on the use of Identity ...

An Enhanced Authentication and Key Agreement Mechanism for SIP Using Certificateless Public-key Cryptography

2008 The 9th International Conference for Young Computer Scientists, 2008
The session initiation protocol (SIP) is considered as the dominant signaling protocol for calls over the Internet. However, how to authenticate each other and agree on a session key has not been efficiently solved. In 2007, Wang and Zhang proposed a key agreement protocol and a new authentication and key agreement mechanism for SIP.

An Authentication and Key Agreement Mechanism for Multi-domain Wireless Networks Using Certificateless Public-Key Cryptography

Wireless Personal Communications, 2014
With rapid growth of mobile wireless networks, handheld devices are popularly used by people and many mobile applications have been rapidly developed. Mutual authentication and key agreement are very important security mechanisms in wireless network systems for preventing unauthorized network access, server impersonation attack and malicious attacks of

Self-Generated-Certificate Public Key Cryptography and certificateless signature/encryption scheme in the standard model

Proceedings of the 2nd ACM symposium on Information, computer and communications security, 2007
Certificateless Public Key Cryptography (CL-PKC) enjoys a number of features of Identity-Based Cryptography (IBC) while without having the problem of key escrow. However, it does suffer from an attack where the adversary, Carol, replaces Alice's public key by someone's public key so that Bob, who wants to send an encrypted message to Alice, uses Alice ...

Efficient Revocation of Security Capability in Certificateless Public Key Cryptography

2005
This paper presents the first mediated certificateless public key encryption and signature schemes. We also extend our schemes into hierarchical schemes. Our schemes does not suffer from the key escrow property that seems to be inherent in the mediated identity-based schemes.

Combining Incomparable Public Session Keys and Certificateless Public Key Cryptography for Securing the Communication Between Grid Participants

2007
Securing the communication between participants in Grid computing environments is an important task, because the participants do not know if the exchanged information has been modified, intercepted or coming/going from/to the right target. In this paper, a hybrid approach based on a combination of incomparable public session keys and certificateless ...

An Improved Kerberos Intra-domain Authentication Protocol Based-On Certificateless Public-Key Cryptography

2011
The paper sums up some improvements in Kerberos intra-domain authentication protocol included in many domestic and foreign literatures. By analyzing the limitations of those improvement schemes, an improvement in Kerberos intra-domain authentication protocol based on certificateless public-key thought is proposed.
