Abstract :
In this work we analyze four techniques to protect a cryptographic core, which can be combined to allow for several implementations with different area overheads and protection levels. Experimental results show their efficiency in protecting the core against fault attacks, while being flexible enough to leave other design aspects to be explored by the core provider.
