在这项工作中，我们的目标是减少使用公钥数字签名在安全路由协议的计算成本。两个协议（COSP和IOSP）使用一次性数字签名的介绍，提供公钥数字签名的功能。我们的协议旨在用于代替公钥数字签名，用于签署路由器之间的各种消息交换。与公钥签名相比，我们的速度提高了十倍以上。我们的协议克服了以前工作中发现的缺点，例如时间限制，有限的应用程序以及易失性环境的高存储和计算成本[12]。由于我们的协议是非交互式的，因此它们提供了真正签名的全部功能。然而，我们的协议并不打算完全取代公钥基础设施。相反，公钥基础设施用于设置COSP和IOSP。作为一种通用的方法，我们的协议可以使用公钥密码系统进行有效的消息签名，以同样的方式与公钥密码系统一起使用，以实现有效的数据加密。
In this work, we aim to reduce the computational costs of using public-key digital signatures in securing routing protocols. Two protocols (COSP and IOSP) using one-time digital signatures are introduced to provide the functionality of public-key digital signatures. Our protocols are intended to be used in place of public-key digital signatures for signing all kinds of message exchanges among routers. We obtained more than ten-fold increase in speed compared with public-key signatures. Our protocols overcome the shortcomings identified in previous works, such as timing constraints, limited applications and high storage and computational costs for volatile environments [12]. Since our protocols are non-interactive, they provide full functionality of a true signature. However, our protocols are not intended for replacing public-key infrastructures completely. Instead, public-key infrastructures are used to set up COSP and IOSP. As a general approach, our protocols can be used with public-key cryptosystems for efficient message signing in much the same way as secret-key cryptosystems are used in conjunction with public-key systems for efficient data encryption.
