Z[]环上的两类密码体制
TWO NEW TYPES OF CRYPTOSYSTEMS OVER EISENSTEIN S RING Z[w]
-
摘要: 本文在Eisenstein环Z[]上得到了两类新的密码体制。它们分别是推广的RSA密码体制和自确认密码体制。安全性分别基于环Z[]上整数的分解和Z[]环上离散对数的计算。Abstract: A new type of public key cryptosystem and a new type of auto-authentication cryptosystem over Eisenstein s ring Z[] are presented. The security of these two types of cryptosystems depends on the difficulty of integer factoring and logarithmic computation in Z[] .
