【摘要】：全同態(tài)簽名方案在可驗(yàn)證外包計(jì)算等領(lǐng)域具有重要應(yīng)用,但目前人們還沒(méi)有提出基于身份的全同態(tài)簽名方案.因此,本文給出了基于身份的全同態(tài)簽名方案的安全定義,基于格問(wèn)題構(gòu)造了一個(gè)基于身份的層次型全同態(tài)簽名方案,在標(biāo)準(zhǔn)模型下基于小整數(shù)解問(wèn)題難解性嚴(yán)格證明了所提全同態(tài)簽名方案滿足選擇性身份與選擇性消息數(shù)據(jù)集合攻擊下的存在性不可偽造性.
[Abstract]:Full homomorphic signature schemes have important applications in the field of verifiable outsourced computing, but no identity-based full homomorphic signature schemes have been proposed. Therefore, the security definition of identity-based all-homomorphism signature scheme is given, and an identity-based hierarchical homomorphic signature scheme is constructed based on lattice problem. In the standard model, it is proved strictly that the proposed full homomorphism signature scheme satisfies the existence unforgeability under the attack of selective identity and selective message data set based on the problem of small integer solution.
