本論文基于這兩個方面，主要研究成果如下：對目前存在的多播組密鑰管理方案進(jìn)行了詳細(xì)的研究分析，尤其是邏輯密鑰分層( lkh )和單向函數(shù)樹( oft )方案，并給出oft方案不能前向保密和后向保密的依據(jù)。 - Secondly , in the electronic bank system , the group key is the core secret , once the key is leaked , the whole system will be destroyed . for the goal of reducing risk , this paper adds the concerp of forward - security to group signature . when the key in one time segment is leaked , the document signed or encrypted befor this segment can nor be destroyed . so that it greatly extends the security of the group signature scheme
另外,在電子銀行中,群密鑰是整個系統(tǒng)的最核心機密,如果群密鑰泄露,整個系統(tǒng)將被破壞,為了降低此類風(fēng)險,把損失降到最低,將前向安全的概念引入到群簽名中,當(dāng)某個時間段密鑰泄露后,這個時間段以前所做的簽名文件、加密文件等不會被破壞,因此,這樣就極大地擴展了群簽名的安全屬性。 - In the common signature system , the signed document can be verified illimitably , anyone can verifies its validity with the group key . but in some special setting , large numbers of verifier are not appropriate , sometimes document can only be verified by some designated people . this paper proposes the designated - verifier group signature scheme with the udvs on acjt . at last this paper implements the multi - bank system with above schemes , remedies the limitation of forgoing schemes , and resolves the par value problem . the par value is designated by the bank , and it is binding with the signature , thus the problem of user cheating can be avoided
在普通的簽名系統(tǒng)中,簽名文件是可以無限驗證的,即每個人都可以通過群公鑰來驗證其有效性,但在某些特殊領(lǐng)域,尤其是電子銀行業(yè)務(wù)中,這樣廣泛的驗證人群在某些情況下是不合適的,有時,某些特殊的簽名文件只能有某些指定的驗證者進(jìn)行驗證,本文在acjt方案的基礎(chǔ)上,根據(jù)通用的指定驗證者的方案構(gòu)造了指定驗證者的群簽名方案。
