A Distributed Group Key Management Scheme for Secure Many-to-many Communication

چکیده
Secure one-to-many multicasting has been a popular research area in the resent past. Secure many-tomany multicasting is becoming popular with applications such as private conferencing, distributed interactive simulation etc. Most of the existing secure multicasting protocols use a centralized group manager to enforce access control and for key distribution. In the presence of multiple senders it is desirable to delegate group control authority and key distribution tasks among the senders. We propose a distributed tree based key management scheme to support many-to-many group communication. Our protocol is scalable and places equal trust in all the senders. Key distribution overhead is evenly divided among the senders. We prove the correctness of the proposed protocol and provide a collusion analysis.

متن کاملHybrid Key pre-distribution scheme for wireless sensor network based on combinatorial design
Key distribution is an important problem in wireless sensor networks where sensor nodesare randomly scattered in adversarial environments.Due to the random deployment of sensors, a list of keys must be pre-distributed to each sensor node before deployment. To establish a secure communication, two nodes must share common key from their key-rings. Otherwise, they can find a key- path in which ens...

متن کاملSeparating indexes from data: a distributed scheme for secure database outsourcing
Database outsourcing is an idea to eliminate the burden of database management from organizations. Since data is a critical asset of organizations, preserving its privacy from outside adversary and untrusted server should be warranted. In this paper, we present a distributed scheme based on storing shares of data on different servers and separating indexes from data on a distinct server. Shamir...
