摘要
XTR体制是一种基于有限域乘法群子群中元素迹紧制表示的公钥体制.本文中提出了基于广义XTR的ElGamal体制,并根据XTR的特点和Schnorr签名构造出一种XTR签名.在同等安全条件下,使得加密和签名可以更有效,在计算量、存储量和通讯量上均大幅度降低,且比较容易应用到微机中.
XTR is a public key system based on a method to represent subgroup＇s elements of a multiplicative group of a finite field. In this paper, we present ElGamal cryptosystem based on Extended XTR. And XTR signature scheme is given based on the characters of XTR and schnorr signature. Extended XTR can be easily used in personal computers. Under the same security, applying XTR is more efficient in the encrytion and signature, and can decrease the quantity of computations, memories, and communications.
