WebAlmost all cryptographic algorithms which use groups actually work in subgroups generated by a conventional element; even if the group as a whole is non-abelian, the subgroup is cyclic, thus abelian. The Anshel-Anshel-Goldfeld protocol tries to use non-commutativity itself, and relies on "how much non-abelian" the group is. ...

WebMay 24, 2016 · Cryptography and security applications make extensive use of random numbers and random bits. However, constructing random bit generators and validating these generators are very challenging.

This lack of structure allows them to be plausibly quantum resistant despite Shor’s algorithm, while still having a number of applications. The most famous example of group actions are built from isogenies on elliptic curves.
