    摘要:

    針對(duì)基于屬性的聯(lián)盟鏈應(yīng)用訪問控制模型可能存在拜占庭節(jié)點(diǎn)而導(dǎo)致屬性信息,、訪問控制策略查詢結(jié)果不可信的問題,結(jié)合獼猴桃溯源場(chǎng)景的實(shí)際需求,,提出了一種基于PBFT的聯(lián)盟鏈應(yīng)用訪問控制方案,。該方案使用屬性權(quán)威作為聯(lián)盟鏈實(shí)體組織的屬性證書頒發(fā)機(jī)構(gòu)以及PBFT的查詢驗(yàn)證節(jié)點(diǎn),對(duì)訪問請(qǐng)求內(nèi)容生成簽名并驗(yàn)證,;屬性證書中存儲(chǔ)主體與權(quán)限相關(guān)的屬性信息,;基于PBFT對(duì)用戶屬性,、數(shù)據(jù)屬性,、訪問控制策略查詢驗(yàn)證,確保訪問控制過程的可信性,?;贖yperledger Fabric原型系統(tǒng)測(cè)試表明,當(dāng)記賬節(jié)點(diǎn)中的拜占庭節(jié)點(diǎn)少于節(jié)點(diǎn)總數(shù)1/3時(shí)系統(tǒng)能夠正常運(yùn)行,;當(dāng)交易發(fā)送率在100~1500TPS之間變化時(shí),,交易吞吐量在交易發(fā)送率達(dá)到300TPS后趨于穩(wěn)定,平均時(shí)延在交易發(fā)送率達(dá)到400TPS后趨于穩(wěn)定,滿足聯(lián)盟鏈獼猴桃溯源的應(yīng)用需求,。

    Abstract:

    Aiming at the problem that attribute information and access control policies might be untrustworthy due to the existence of Byzantine nodes in the attribute-based consortium blockchain application access control model, combined with the actual needs of the kiwifruit traceability scenario, an access control scheme of kiwifruit traceability application based on PBFT and consortium blockchain was proposed. The attribute authority was used as the attribute certificate authority of the consortium blockchain entity organization and the query verification node to generate signatures and verify the access request contents. The attribute information related to the subject and the authority was stored in the attribute certificate. The user attributes, data attributes and access control policies based on the PBFT were verified to ensure the credibility of the access control process. The tests based on the Hyperledger Fabric prototype system showed that the system could work normally when the number of Byzantine nodes in the accounting node was less than 1/3. The total number of transactions submitted to the blockchain was 1000, 2000, 3000, and the transaction sending rate was 100TPS, 200TPS, …, 1400TPS and 1500TPS, the transaction throughput was stable when the transaction sending rate was 300TPS, and the average latency was stable when the transaction sending rate was 400TPS. The scheme met the requirements of the consortium blockchain kiwifruit traceability application.
