Abstract: Cryptographic group actions provide a flexible framework that allows the design of several primitives, ranging from key exchange protocols to PRFs and digital signatures. The range of cryptographic schemes that can be built heavily depends on the properties of the considered action, and their security is based on the intractability of some computational problems. In this talk, we explore the space of cryptographic group action using tools from representation theory, and we try to answer the question “Can I use the group action X in the scheme Y?”.
