The Bit-Security of Cryptographic Primitives

By Joël Alwen, Cryptographer

As the Wickr community continues to grow, our engineering & crypto teams are developing new tools and techniques to protect user information while continuously improving our existing security architecture. One of the core concepts that we work with is “bit security,” which refers to the order of magnitude of the amount of resources needed to break a crypto primitives’ security.

In this post, I’ll share a quick overview of the bit security of several common generic types of cryptographic primitives as well as a few specific examples used by the Wickr protocol and why they were chosen by our team.
