一種可認(rèn)證的動(dòng)態(tài)秘密共享方案
A verifiable dynamic secret sharing scheme
-
摘要: 該文基于橢圓曲線加密的安全性提出了一種改進(jìn)的秘密共享方案。該方案可防欺騙、防參與者數(shù)據(jù)誤發(fā),參與者和管理者相互之間能相互進(jìn)行身份認(rèn)證,并且較好地解決了秘密共享的更新和復(fù)用問(wèn)題,該方案在現(xiàn)在網(wǎng)絡(luò)通信中有較高的應(yīng)用價(jià)值。

Abstract: In the paper, an improved secret sharing scheme based on elliptic curve cryptography is proposed. It guarantees the mutual identity authentication between the legal dealer and the participating parties and can protect against the cheating action. The problems of renew and reuse are properly treated. The scheme may be applicable in practical network communication. -
