The FHE transpiler as it is today carries all the restrictions of the FHE programming paradigm in addition to those imposed by the HLS tools used. Having clean interfaces between the three layers both limits development complexity and provides a separation of responsibilities. 29.
The frontend uses XLSccp to generate XLS-IR from a C++ input program. For example, one could choose to transpile the program into a TFHE cryptosystem backend or a CKKS backend. // End hiding -->. Enter encryption key e and plaintext message M in the table on the left, then click the Encrypt button. As part of its toolchain, it provides functionality to compile high-level hardware designs down to lower levels, and eventually to Verilog.44 This compilation step introduces a flexible intermediate representation (XLS IR) in the form of a computational circuit (see Figure 5). m. FHE transpiler; https://github.com/google/fully-homomorphic-encryption. By limiting complexity, developers can focus on writing application code. Create an ACM Web Account 6. Bootstrapping is an understandably expensive operation, and much research around FHE today attempts to avoid or accelerate it.
