Also we analysed in detail the characteristics on pathologic morphology of MUO in elderly that had the significance on suggesting th origin sites. 并对原发灶的明确有提示意义的病理形态特征进行了详细的分析。
In respect to the shortcomings of Mambo-Usuda-Okamoto's proxy signature, this paper proposes a new proxy signature scheme by introducing MUO proxy signature and elliptic-curve algorithm, and applying ECDSA into MUO. 首先分析了Mambo-Usuda-Okamoto的代理签名方案的不足,通过引入MUO代理签名及椭圆曲线算法,将ECDSA应用于MUO方案。
