Fully Homomorphic Encryption (FHE) allows a third party to perform arbitrary computations on encrypted data, learning neither the inputs nor the computation results. However, the complexity of developing an efficient FHE application currently limits deploying FHE in practice. In this talk, we will first present the underlying challenges of FHE development that motivate the development of tools and compilers. We then discuss how MLIR has been used by three different efforts, including one led by us, to significantly advance the state of the art in FHE tooling. While MLIR has brought great benefits to the FHE community, we also want to highlight some of the challenges experienced when introducing the framework to a new domain. Finally, we conclude by discussing how the ongoing efforts could be combined and unified before potentially being up-streamed.
