Design and Implementation of Certificateless Cryptography for IoT Applications

2023 IEEE 66th International Midwest Symposium on Circuits and Systems (MWSCAS), 2023
This work introduces a cryptographic module for IoT devices that addresses the security vulnerabilities that come with their widespread adoption. Four core cryptographic mod- ules are implemented, including data confidentiality, message integrity, authentication, and secure communication channels.

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 ...

A Provably Secure Threshold Ring Signature Scheme in Certificateless Cryptography

2010 International Conference of Information Science and Management Engineering, 2010
Ring signature is a kind of group-oriented signature. It allows a member of a group to sign messages on behalf of the group without revealing his/her identity. Certificateless public key cryptography was first introduced by Al-Riyami and Paterson at Asiacrypt 2003.

Two-party authenticated key agreement in certificateless public key cryptography

Wuhan University Journal of Natural Sciences, 2007
Certificateless public key cryptography was introduced to overcome the key escrow limitation of the identity-based cryptography. It combines the advantages of the identity-based cryptography and the traditional PKI. Many certificateless public key encryption and signature schemes have been proposed.

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 modest approach on MANET using certificateless cryptography

2017 International Conference on Intelligent Sustainable Systems (ICISS), 2017
A MANET is an independent collection of mobile devices that communicate with each other. The use a wireless links and work together in a distributed manner. This network, the Security is the most important attention because of its lack of centralized devices. In mobile ad hoc networks, the load and complication for key management is intensely dependent

Efficient three-party authenticated key agreement protocol in certificateless cryptography

International Journal of Computer Mathematics, 2011
Key agreement protocols are multi-party protocols in which entities exchange public information allowing them to create a common secret key that is known only to those entities and which cannot be predetermined by any party. Key agreement can be achieved using a public key infrastructure or identity-based cryptography.
