【摘要】：隨著無(wú)紙化辦公的發(fā)展,電子簽章系統(tǒng)作為電子商務(wù)和電子政務(wù)系統(tǒng)的強(qiáng)有力的安全依托,在現(xiàn)實(shí)生活中受到廣泛地應(yīng)用。電子簽章是具有中國(guó)特色的一種表現(xiàn)形式,其完美地將中國(guó)古老的印璽文化和電子簽名有機(jī)地結(jié)合起來(lái),是隨著計(jì)算機(jī)網(wǎng)絡(luò)的飛速發(fā)展和信息技術(shù)安全廣泛應(yīng)用而產(chǎn)生的�，F(xiàn)如今,我國(guó)的電子簽章技術(shù)的發(fā)展如火如茶地進(jìn)行著,多家軟件公司和高校、研究所也參與到電子簽章系統(tǒng)的研發(fā)當(dāng)中,相繼產(chǎn)生了許多切實(shí)可行的電子簽章系統(tǒng)方案。同時(shí),我國(guó)國(guó)家密碼管理局也會(huì)定期出臺(tái)一套符合當(dāng)前密碼管理需求的電子簽章設(shè)計(jì)標(biāo)準(zhǔn),依靠該標(biāo)準(zhǔn)的規(guī)范性設(shè)計(jì)和《電子簽名法》的法律依托,電子簽章技術(shù)得以廣泛地開(kāi)發(fā)和應(yīng)用。伴隨電子簽章系統(tǒng)的發(fā)展,越來(lái)越多相關(guān)的需求也相繼被提出。傳統(tǒng)的電子簽章系統(tǒng)設(shè)計(jì)中,每個(gè)電子印章只有一個(gè)用戶(hù)所擁有,或者對(duì)于驗(yàn)簽人來(lái)說(shuō),該電子印章的歸屬信息是完全透明的。但是在有些特殊應(yīng)用領(lǐng)域,如電子現(xiàn)金、電子投票、匿名舉報(bào)、有關(guān)部門(mén)發(fā)文等,需要隱藏簽名人的具體信息。此時(shí),要求驗(yàn)簽人只需獲悉電子簽章的有效性和電子印章的單位歸屬即可,不需要獲得具體的簽章人信息。電子簽章系統(tǒng)的設(shè)計(jì)依賴(lài)于數(shù)字簽名的算法設(shè)計(jì)及其簽名策略的方案設(shè)計(jì)。從簽名策略的角度,相繼出現(xiàn)了盲簽名、代理簽名、群簽名和環(huán)簽名等簽名方案,其應(yīng)用范圍根據(jù)現(xiàn)實(shí)的需求互不相同。其中,群簽名和環(huán)簽名的性能相似,即一個(gè)群或環(huán)中任何一個(gè)成員可以代表這個(gè)群或環(huán)對(duì)數(shù)據(jù)進(jìn)行簽名,驗(yàn)簽人只能驗(yàn)證該簽名的有效性,但無(wú)法判定具體的簽名人信息,均具有簽名匿名性的特點(diǎn)。不同的是,相比群簽名,環(huán)簽名沒(méi)有設(shè)置管理員的角色,環(huán)中所有簽名用戶(hù)的等級(jí)是相同的,彌補(bǔ)了群簽名中群管理員可以查看簽名人信息的缺陷,因此,環(huán)簽名時(shí)無(wú)條件匿名的,滿(mǎn)足上述對(duì)具體簽名人有所隱藏的需求。本文基于國(guó)家科技課題****撰寫(xiě)的。通過(guò)研究環(huán)簽名的技術(shù)策略和傳統(tǒng)電子簽章系統(tǒng)的特點(diǎn),提出基于環(huán)簽名的電子簽章系統(tǒng)設(shè)計(jì)方案,并從底層測(cè)試和系統(tǒng)測(cè)試兩個(gè)角度對(duì)該方案進(jìn)行了實(shí)現(xiàn),滿(mǎn)足某些特殊領(lǐng)域?qū)﹄娮雍炚孪到y(tǒng)的需求。同時(shí),提出新方案和傳統(tǒng)電子簽章系統(tǒng)設(shè)計(jì)的集成策略,有效較低了系統(tǒng)開(kāi)發(fā)成本。
[Abstract]:With the development of paperless office, electronic signature system, as a strong security support of electronic commerce and e-government system, is widely used in real life. Electronic signature is a form of expression with Chinese characteristics, which perfectly combines the ancient Chinese seal culture with electronic signature. It is produced with the rapid development of computer network and the wide application of information technology. Nowadays, with the development of electronic signature technology in our country, many software companies and universities and research institutes are also involved in the research and development of electronic signature system, and many feasible electronic signature system schemes have been produced one after another. At the same time, the State Cryptography Administration of our country will regularly issue a set of electronic signature design standards that meet the needs of current password management, relying on the normative design of the standard and the legal backing of the Electronic signature Law. Electronic signature technology has been widely developed and applied. With the development of electronic signature system, more and more related requirements have been put forward. In the traditional design of electronic signature system, each electronic seal is owned by only one user, or for the signer, the ownership information of the electronic seal is completely transparent. However, in some special applications, such as electronic cash, electronic voting, anonymous reporting, relevant departments, etc., it is necessary to hide the specific information of the signer. At this point, the signer only needs to know the validity of the electronic signature and the unit ownership of the electronic seal, and does not need to obtain the specific information of the signer. The design of electronic signature system depends on the algorithm design of digital signature and the scheme design of signature strategy. From the point of view of signature strategy, blind signature, proxy signature, group signature and ring signature have emerged in succession, and their applications are different according to the needs of reality. The performance of group signature is similar to that of ring signature, that is, any member of a group or ring can sign the data on behalf of the group or ring, and the signer can only verify the validity of the signature, but can not judge the specific signer information. All of them have the characteristics of anonymity. The difference is that compared to group signature, ring signature has no administrator role, and all signing users in the ring have the same rank, which makes up for the defect that group administrator can view signer information in group signature, so, The ring signature is unconditionally anonymous, which satisfies the needs of the specific signer mentioned above. This paper is based on the National Science and Technology Project. By studying the technical strategy of ring signature and the characteristics of traditional electronic signature system, the design scheme of electronic signature system based on ring signature is put forward, and the scheme is implemented from two angles of bottom test and system test. Meet the needs of electronic signature system in some special fields. At the same time, the integration strategy of the new scheme and the traditional electronic signature system design is put forward, which effectively reduces the system development cost.
