【摘要】:針對(duì)P2P網(wǎng)絡(luò)內(nèi)部的安全問(wèn)題,提出了一種P2P網(wǎng)絡(luò)基于直接交易信任和推薦信任的模型,運(yùn)用了直接交易信息參數(shù)、推薦信息的評(píng)價(jià)可信度和動(dòng)態(tài)平衡權(quán)值參數(shù),較簡(jiǎn)單準(zhǔn)確地描述了節(jié)點(diǎn)的綜合信任值,在進(jìn)行交易前與目標(biāo)節(jié)點(diǎn)建立信任關(guān)系,能有效抑制惡意節(jié)點(diǎn)對(duì)網(wǎng)絡(luò)中其他節(jié)點(diǎn)的惡意交易行為和評(píng)價(jià)欺騙,提高網(wǎng)絡(luò)交易的安全性。
[Abstract]:Aiming at the internal security problem of P2P network, a P2P network model based on direct transaction trust and recommendation trust is proposed. The parameters of direct transaction information are used to evaluate the reliability of recommendation information and the dynamic balance weight parameter. The comprehensive trust value of the node is described simply and accurately, and the trust relationship with the target node before the transaction is established, which can effectively restrain the malicious transaction behavior of the malicious node to the other nodes in the network and evaluate the deception, and improve the security of the network transaction.
