In this paper, we describe a secure group communication protocol for a fault-tolerant synchronous ring. Our protocol, named Secure Synchronous Ring Protocol (SSRP), integrates a secure group communication facility into an existing scalable, fault-tolerant ring protocol. SSRP is a hierarchical group communication protocol that employs Cliques GDH contributory key management protocol and Diffie-H...

This paper introduces a new group communication component designed to provide adaptiveness and high availability in a broad sense. The key element of the system is a switching protocol that enables replacing in runtime the currently used group communication protocol by a different one. Such an architecture can take advantage of the different features of various group communication protocols by ...

Quantum fingerprints are useful quantum encodings introduced by Buhrman, Cleve, and Watrous (Physical Review Letters, Volume 87, Number 16, Article 167902, 2001) in obtaining an efficient quantum communication protocol. We design a protocol for constructing the fingerprint in a distributed scenario. As an application, this protocol gives rise to a communication protocol more efficient than the ...

This paper introduces a secure communication protocol that provides secured pathways to manipulate drones through unsecured communication. The deployment of the proposed works providing two paths; drone’s controller path and data centre path. first has achieved high level security privacy by using modification SHA-1 method an advanced encryption method. is called 83SHA-1. These modifications ca...

Current technologies for managing rail traffic such as the Global System Mobile communications Railway (GSM-R) will be no longer available within upcoming years. The European Shift2Rail Joint Undertaking (S2R-JU) proposed Adaptable Communication (ACS) to overcome this problem. In work, we model ACS by abstracting it at Internet Protocol (IP) level, using tunnels datagrams’ transmission a commun...
