摘要 Anderson于 1996年研究发现了ELGamal签名中的一类结合宽带和窄带信道优点的阈下信道 ,称为牛顿信道 .该文在考虑签名安全性的前提下深入研究了牛顿信道的带宽 ,主要是签名作用子群与牛顿信道带宽的关系 .文章的后面给出了DSA中一个带宽不太大 ,实用性强 ,计算复杂度小的牛顿信道设计方案 . Anderson discovered a new subliminal channel in ElGamal signature, called Newton channel in 1996. The channel has a large bandwidth and does not require the sender to compromise the security of her signing key. In this paper, considering the signature's security, the bandwidth of Newton channel is deeply researched with the emphasis on the relation between the subgroup of generating signature and the bandwidth of Newton channel. Finally a Newton channel scheme in DSA is given. Its bandwidth is not very large, but it has a good practicability and a low computational complexity.
