A Fast Handover protocol (FMIPv6) in IETF working group is proposed to reduce the handover latency in Mobile IPv6 standard protocol. The FMIPv6 proposes some procedures for fast movement detection and fast binding update to minimize the handover latency. Additionally, to reduce the lost packets caused by a handover, this protocol introduces buffers in access routers. However, the handover laten...

This letter proposes a group key distribution scheme using smart contract-based blockchain technology. The contract’s functions allow for securely distributing the session key, following initial legitimacy detection public infrastructure-based authentication. For message authentication, we propose lightweight symmetric cryptography-based signature method, supporting security and privacy require...

Focusing on the problem that existing traditional cross-domain group authentication schemes have a high complexity, certificateless key agreement scheme based ECC is proposed. The protocol provides scalability and can meet requirements of negotiation by multiple participants in different domains. Security analysis shows proposed secure random oracle security model, it resist some attacks under ...

In IP-based wireless/mobile networks, minimizing handover latency is one of the most important issues. Fast handover mobile IPv6 (FMIPv6) reduces the handover latency by handover prediction with link-layer information. It requires additional overhead in terms of signaling and may waste resources by incorrect prediction. In this paper, we introduce a new non-predictive handover scheme which empl...

Efficient reliable multicast transport reducing the receiver processing overhead and allowing seamless continuation of the multicast service in case of handover is a challenge of today broadband infrastructures including content and mobile networks, The focus of this paper are protocol mechanisms aimed at scalable reliable point-to-multipoint content delivery from access routers to the attached...

In hospital settings, the quality and effectiveness of shift handover are critical for continuous and high quality patient care. This paper explores nurses’ knowledge sharing problems during shift handover in 6 Australian hospitals. A single focus group was conducted to collect empirical evidence of knowledge sharing problems during shift handover, across the hospitals. Findings indicate a broa...

Deniable authentication protocol is different from traditional authentication protocol in that the intended receiver can authenticate the source of a given message, but cannot prove the source to a third party. In recent years, many deniable authentication protocols have been put forth. To adapt to some special group communication requirements, in this paper, we will propose a new group oriente...
