Security techniques

The author considers the range of security techniques available to future designers and implementers of telecommunications networks. The primary focus is on mobile networks, which is where much of the recent public effort on telecommunications security has been exerted. However, the techniques described are of general applicability in telecommunications. He defines what is meant by a security technique; distinguishing between security features and security techniques (or security mechanisms, as security techniques are often known). In looking at techniques appropriate to telecommunications networks he summarises the progress which has been made in recent years in providing general-purpose standards for security techniques.
