Z[]環(huán)上的兩類密碼體制
TWO NEW TYPES OF CRYPTOSYSTEMS OVER EISENSTEIN S RING Z[w]
-
摘要: 本文在Eisenstein環(huán)Z[]上得到了兩類新的密碼體制。它們分別是推廣的RSA密碼體制和自確認密碼體制。安全性分別基于環(huán)Z[]上整數的分解和Z[]環(huán)上離散對數的計算。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[] .
