Secure Ad-Hoc mBusiness: Enhancing WindowsCE Security

摘要

Nowadays we can perform business transactions with remote servers interconnected to Internet using our personal devices. These transactions can also be possible without any infrastructure in pure ad-hoc networks. In both cases, interacting parts are often unknown, therefore, they require some mechanism to establish ad-hoc trust relationships and perform secure transactions. Operating systems for mobile platforms support secure communication and authentication, but this support is based on hierarchical PKI. For wireless communications, they use the (in)secure protocol WEP. This paper presents a WCE security enhanced architecture allowing secure transactions, mutual authentication, and access control based on dynamic management of the trusted certificate list. We have successfully implemented our own CSP to support the new certificate management and data ciphering.
