An efficient certificateless cryptography scheme without pairing

Proceedings of the third ACM conference on Data and application security and privacy, 2013
We propose a mediated certificateless encryption scheme without pairing operations. Mediated certificateless public key encryption (mCL-PKE) solves the key escrow problem in identity based encryption and certificate revocation problem in public key cryptography.

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

Certificateless Cryptography with KGC Trust Level 3 Revisited

2017
This paper revisits the issue of obtaining KGC (Key Generator Center) trust level 3 in certificateless cryptography. The AP (Al-Riyami-Paterson) binding technique can modularly construct the certificateless encryption/signature scheme with trust level 3 from that with trust level 2. However, its security proof has been an open problem.

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.

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.

Key management scheme based on certificateless cryptography for satellite networks

2012 2nd International Conference on Consumer Electronics, Communications and Networks (CECNet), 2012
The article proposes a key management scheme for satellite networks targeting the problem of existing key management scheme cannot be suitable for satellite networks. Threshold secret mechanism is used to achieve the protection for system master key, and avoid the single point of failure problem.

A pairing-free certificateless digital multisignature scheme using elliptic curve cryptography

International Journal of Computer Mathematics, 2015
In a digital multisignature scheme, two or more signers are allowed to produce a single signature on a common message, which can be verified by anyone. In the literature, many schemes are available based on the public key infrastructure or identity-based cryptosystem with bilinear pairing and map-to-point MTP hash function. The bilinear pairing and the

CertificateLess Cryptography-Based Rule Management Protocol for Advanced Mission Delivery Networks

2017 IEEE 37th International Conference on Distributed Computing Systems Workshops (ICDCSW), 2017
Assured Mission Delivery Network (AMDN) is a collaborative network to support data-intensive scientific collaborations in a multi-cloud environment. Each scientific collaboration group, called a mission, specifies a set of rules to handle computing and network resources.

TIBC: Trade-off between Identity-Based and Certificateless Cryptography for future internet

2009 IEEE 20th International Symposium on Personal, Indoor and Mobile Radio Communications, 2009
Identity-Based Cryptography (IBC) offers the very interesting property that the user's public key is related directly to her/his identity. However, IBC suffers from key escrow because the user private key is generated by an external entity called the Private Key Generator (PKG).
