Abstract:
In 2016, US NIST released the KMAC message authentication code, which is actually a keyed variant of the new-generation hash function standard SHA-3. Following the increasing use of SHA-3, it is highly anticipated that KMAC will also be increasingly widely used in various security applications. Due to the distinctions between sponge hash functions and Merkle-Damgård hash functions, white-box implementations of KMAC and HMAC are rather different. In this paper, we present an efficient white-box implementation of KMAC with strong resistance against both key extraction and code lifting attacks, which can still work with an updated user key. It has a storage complexity of about 107.7 MB, and has a running time of about 1.5 ms on a DELL Precision T5610 workstation, about 375 times slower than the original KMAC implementation without white-box protection. There are implementation variants with different trade-offs between security and performance. This is the first published white-box implementation of KMAC to the best of our knowledge, and our implementation methods can be applied to similar sponge constructions.
