Abstract

In mobile computing applications the traditional name-based concept of identity is both difficult to support and frequently inappropriate. The natural alternative is to use the context in which parties sit to identify them. We discuss this issue and the ways in which Human Interactive Security Protocols (HISPs) can play a role in enabling this.
