A detachable IPsec device for secure consumer communication

Communications among consumer appliances are often directly related to user's privacy. Unfortunately, most of the consumer appliances are not sufficiently equipped with security and privacy protection functions. We propose IPsec-Proxy technology which is implemented on a security device that can protect privacy, at the same time maintaining simplicity of operations of current appliances. It enables to incrementally attach IPsec functions on consumer communication networks as well as detach them from the networks by simply eliminating themselves. We have implemented it on a small PC running as an IP bridge and measured the performance. Throughout our proposal, we have confirmed the feasibility of the security protection platform for privacy-related information using IPsec-Proxy technology. Our platform requires neither modifications nor additional customization to the current consumer appliances.
