... the namespace. We show that the capability filenames used in CapaFS are a secure and practical solution to sharing resources.

The results of CapaFS show that the cost of software encryption can be tolerated in large networks like the Internet, where the cost of encryption is a small percentage of the total delay. CapaFS offers new functionality to users which sucessfully promotes the sharing of files and collaboration on the Internet, without imposing significant costs in terms of overhead and performance.
