HETOCompiler: An MLIR-based crypTOgraphic Compilation Framework for HEterogeneous Devices

Hash algorithms are fundamental tools in cryptography, offering irreversible and sensitive transformations of input data for various security purposes. As computing architectures evolve towards heterogeneous systems, efficiently harnessing diverse computing resources for hash encryption algorithms becomes crucial. This paper presents HETOCompiler, a novel cryptography compilation framework designed for heterogeneous systems. Leveraging Multi-Level Intermediate Representation (MLIR), HETOCompiler abstracts syntax and semantics for cryptographic primitives and heterogeneous computing models, facilitating efficient compilation of high-level hash encryption algorithms into executable programs compatible with diverse devices. Experimental results demonstrate significant performance improvements over existing OpenSSL library, with average enhancements of 49.3x, 1.5x, and 23.4x for SHA-1, MD5, and SM3 algorithms respectively.
