針對現(xiàn)有前向安全數(shù)字簽名方案中無法保證后向安全性,且存在偽造攻擊等問題，本文提出了一種基于橢圓曲線密碼體制的強前向安全數(shù)字簽名方案。本文方案通過引入雙密鑰技術(shù)，使攻擊者即便得到某一時段的兩個密鑰也無法偽造該時段以外其他時段的有效簽名，從而確保該方案具備“雙向安全性”。通過對方案安全性和運算量的分析，表明該方案不僅正確有效、安全性高，并且具有運算量小，運行效率高等特點。該方案具有重要的理論和實用價值。 In view of the existing forward secure digital signature scheme can’t guarantee to safety,and some problems such as forgery attacks,this paper presents a kind of strong forward secure digital signature scheme based on elliptic curves cryptosystems .The scheme of this paper makes attacker couldn’t forge the signer’s the time other time valid signature by introducing dual key technology even if they get the signer’s a period of two keys,to ensure that the scheme has “two-way security”.Through the security and computational complexity analysis of the scheme,it show that the scheme not only correct,valid and high safety,but has smaller computational complexity,higher efficiency,etc.The scheme has important theoretical and practical value. |

| In view of the fact that the existing forward secure digital signature scheme can not guarantee safety,and it has some problem such as forgery attacks,this paper presented a kind of strong forward secure digital signature scheme based on elliptic curves cryptosystems .Such scheme prevent attackers from forging the signer’s valid signature of both time point by introducing dual key technology even if they get the signer’s two keys of a certain period to aquire “two-way security”.The security and computational complexity analysis of the scheme showed that it was not only correct,valid and highly safety,but with smaller computational complexity,higher efficiency,etc.,and has important theoretical and practical value. |
