Abstract

Various types of certificates are basic tools of modern cryptography and network security. They are used in various protocols, in the form of public key identity certificates, binding a key to its owner or in the form of attribute certificates, being a proof of rights and capabilities of their owner. Management of certificates (creation, distribution, verification, and revocation) is dependent on a certification infrastructure comprising various certification authorities, protocols, and policies. In this paper we consider usage and management of certificates in open, ad hoc networks. Ad hoc networks differ from fixed, wired networks in several important aspects, one of them being that access to the Internet is not always available. This significantly influences certificate management protocols since online access to various certificate system resources (CA certificates, CRL, etc) is not always available. We specify security requirements and constraints in such environments and outline potential solutions for adaptation of certificate management protocols to these new network environments.

自组织网络中的证书管理

各类证书是现代密码学和网络安全的基本工具。它们以公钥身份证书的形式用于各种协议，将密钥绑定到其所有者，或者以属性证书的形式用于证明其所有者的权利和能力。证书的管理(创建、分发、验证和撤销)依赖于由各种证书颁发机构、协议和策略组成的证书基础设施。在本文中，我们考虑了在开放的自组织网络中证书的使用和管理。自组织网络在几个重要方面与固定的有线网络不同，其中之一是对Internet的访问并不总是可用的。这极大地影响了证书管理协议，因为对各种证书系统资源(CA证书、CRL等)的在线访问并不总是可用的。我们指定了此类环境中的安全需求和约束，并概述了使证书管理协议适应这些新网络环境的潜在解决方案。
