چکیده

At Crypto-87 conference, we proposed identity-based key distribution systems for generating a common secret conference key for two or more users. Protocols were shown for three configurations: a ring, a complete graph, and a star. Yacobi has made an impersonation attack on the protocols for the complete graph and star networks. This paper proposes improved identity-based key distribution protocols to counter his attack.

Provably secure and efficient identity-based key agreement protocol for independent PKGs using ECC

Key agreement protocols are essential for secure communications in open and distributed environments. Recently, identity-based key agreement protocols have been increasingly researched because of the simplicity of public key management. The basic idea behind an identity-based cryptosystem is that a public key is the identity (an arbitrary string) of a user, and the corresponding private key is ...

Private Key based query on encrypted data

Nowadays, users of information systems have inclination to use a central server to decrease data transferring and maintenance costs. Since such a system is not so trustworthy, users' data usually upkeeps encrypted. However, encryption is not a nostrum for security problems and cannot guarantee the data security. In other words, there are some techniques that can endanger security of encrypted d...

Improving Identity-based Random Key Establishment Scheme for Large-Scale Hierarchical Wireless Sensor Networks

In this paper, we propose a novel identity-based random key pre-distribution scheme called the identity based key pre-distribution using a pseudo random function (IBPRF), which has better trade-off between communication overhead, network connectivity and resilience against node capture compared to the other existing key predistribution schemes. IBPRF always guarantees that no matter how many se...

Rethinking the security of some authenticated group key agreement schemes

In this paper we analyse three improved authenticated group key agreement schemes, all of which are based on the conference key distribution systems proposed by Burmester and Desmedt. We show that all the schemes suffer from a type of impersonation attack, although these schemes are claimed to be secure.

A novel key management scheme for heterogeneous sensor networks based on the position of nodes

Wireless sensor networks (WSNs) have many applications in the areas of commercial, military and environmental requirements. Regarding the deployment of low cost sensor nodes with restricted energy resources, these networks face a lot of security challenges. A basic approach for preparing a secure wireless communication in WSNs, is to propose an efficient cryptographic key management protocol be...
