Security protocols in constrained environments

Implementation of security protocols such as TLS, SSH or IPsec come with a memory and compute overhead. Whilst this has become negligible in full scale environments it’s still a real issue for hobbyist and embedded developers. This presentation will look at the sources of the overheads, what can be done to minimise them, and what sort of hardware platforms can be made to absorb them. The benefits and potential pitfalls of hardware specific implementations will also be examined.

Chris has tinkered with electronics since pre-school, and these days has a desk littered with various dev boards and projects.
