基于區(qū)塊鏈的跨異構(gòu)域認(rèn)證方案基于區(qū)塊鏈的跨異構(gòu)域認(rèn)證方案
摘要:隨著互聯(lián)網(wǎng)技術(shù)的發(fā)展,人們對(duì)于網(wǎng)絡(luò)安全的需求越來越高,而且各個(gè)行業(yè)之間的信息交流也越來越頻繁,為了實(shí)現(xiàn)不同行業(yè)之間的互聯(lián)互通,提高網(wǎng)絡(luò)安全性,需要一種有效的跨異構(gòu)域認(rèn)證方案。而區(qū)塊鏈技術(shù)以其分布式、去中心化、不可篡改等特點(diǎn)成為了解決該問題的有效手段。
本文旨在提出一種基于區(qū)塊鏈的跨異構(gòu)域認(rèn)證方案。該方案基于分布式賬本技術(shù),利用智能合約實(shí)現(xiàn)跨異構(gòu)域身份認(rèn)證,并采用區(qū)塊鏈技術(shù)的去中心化、不可篡改特點(diǎn)保障認(rèn)證過程的安全性、可靠性和高效性。首先,本方案定義了基礎(chǔ)身份標(biāo)識(shí)的結(jié)構(gòu),并建立了一個(gè)基礎(chǔ)身份信息的數(shù)字化存儲(chǔ)庫。然后,對(duì)于不同域內(nèi)的身份信息認(rèn)證問題,本方案設(shè)計(jì)了一種基于多重簽名的去中心化認(rèn)證過程,每個(gè)域內(nèi)的用戶均可參與到認(rèn)證過程中,保障了認(rèn)證過程的安全性和可信度。本方案利用智能合約確保了基于區(qū)塊鏈的跨異構(gòu)域認(rèn)證過程的高效實(shí)施。最后,本文通過實(shí)驗(yàn),驗(yàn)證了該方案的可行性和優(yōu)越性。
