在像P2P这样的去中心化系统中，每个节点都是相当自治的，节点之间的相互信任的概念至关重要。此外，当环境受到内在资源限制时，任何提高效率的努力都是必要的。针对这两个问题，我们提出了一种新的基于可信度的高效广播方案在资源受限的P2P环境。可信度与对等体的声誉相关联。一个同行持有一个个性化的看法，对其他同行的声誉在四个类别，即SpEed，正确性，质量，和无风险（SeCuRE）。每个类别的值构成了单个对等体可靠性的一小部分。另一个影响对等点可靠性的因素是对等点在提供关于其他对等点的推荐时的可信度。我们的信任管理计划与我们的信任模型，以检测恶意和协作为基础的恶意同行。知识的可信度之间的同行被用于我们提出的广播模型命名为基于可信度的estafet多点中继（TEMPR）。该模型的目的是最大限度地减少对等点之间的通信开销，同时考虑到对等点的可信度，只有值得信赖的对等点可以中继消息到其他对等点。通过我们的方法，每个节点都能够以最有效和可靠的方式传播消息。
In a decentralised system like P2P where each individual peers are considerably autonomous, the notion of mutual trust between peers is critical. In addition, when the environment is subject to inherent resource constraints, any efficiency efforts are essentially needed. In light of these two issues, we propose a novel trustworthy-based efficient broadcast scheme in a resource-constrained P2P environment. The trustworthiness is associated with the peerʼs reputation. A peer holds a personalised view of reputation towards other peers in four categories namely SpEed, Correctness, qUality, and Risk-freE (SeCuRE). The value of each category constitutes a fraction of the reliability of individual peer. Another factor that contributes to the reliability of a peer is the peerʼs credibility concerning trustworthiness in providing recommendation about other peers. Our trust management scheme is applied in conjunction with our trust model in order to detect malicious and collaborative-based malicious peers. Knowledge of trustworthiness among peers is used in our proposed broadcast model named trustworthy-based estafet multi-point relays (TEMPR). This model is designed to minimise the communication overhead between peers while considering the trustworthiness of the peers such that only trustworthy peer may relay messages to other peers. With our approach, each peer is able to disseminate messages in the most efficient and reliable manner.
