![]() ![]() In the world of block ciphers, AES has been king for quite a few years. A block cipher with some properties that I think makes it a viable alternative to the block cipher AES for some applications. In this post we will take a look a what lightweight algorithms means as well as looking at a fairly recent lightweight block cipher called PRINCE, which I have implemented. To that effect I'm continuously developing and releasing open hardware implementations of ciphers, hash functions, block cipher modes. I have found that one way to really gain familiarity with a cryptographic primitive is to implement it. ![]() ![]() A term quite often used in this context is lightweight algorithms. With the prevalence of Internet of Things (IoT) and increased connectivity in automotive space, that need keeps increasing. Working with customers developing embedded systems one often needs compact cryptographic primitives to implement the security functions required by the applications running on the systems. ![]()
