Efficient, Flexible and Secure Group Key Management Protocol for Dynamic IoT Settings

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 ...

Secure and efficient group key management with shared key derivation

In many network applications, including distant learning, audio webcasting, video streaming, and online gaming, often a source has to send data to many receivers. IP multicasts and application-layer multicasts provide efficient and scalable one-to-many or many-to-many communications. A common secret key, the group key, shared by multiple users can be used to secure the information transmitted i...

Efficient Key Management for Secure Group Communications with Bursty Behavior

Secure group communication (SGC) is becoming more popular in the Internet. Burstiness is an important behavior in SGC. Performing bursty operation in one aggregate operation is important for efficiency and scalability. In this paper, we extend the well-known key-tree key management protocol for SGC to situations with bursty user arrival and departure patterns. By using a binary representation t...

Efficient Collaborative Key Management Protocols for Secure Autonomous Group Communication

Secure Group Key Management for Dynamic Sensor Networks

Problem statement: Key management is an important cryptographic technique for providing security in a dynamic environment of sensor networks. To provide a secure communication among a group of sensor nodes keys should established in an efficient manner. We introduced an efficient and dynamic key management system for dynamic sensor networks. Approach: We pre deployed some of the keying material...
