Compact Versatile Core for SHA-3-224/256/384/512 and (c)SHAKE-128/256

 XIP3030C is a compact IP core designed for versatile support of all variants of the SHA-3 hash func tion and related extendable-output function SHAKE as well as the SHA-3 derived function cSHAKE and its variants KMAC, TupleHash and ParallelHash (including their arbitrary-length output vari ants). SHA-3 and SHAKE are defined in the NIST (National Institute of Standards and Technology) standard FIPS PUB 202 [1] and cSHAKE, KMAC, TupleHash and ParallelHash are specified in NIST Special Publication 800-185 [2]. Because of the versatile algorithm support, XIP3030C can be used in various applications that require SHA-3 hashing or other supported SHA-3 based functionali ties. XIP3030C consumes only small amounts of FPGA resources that allows it to be used even in settings where resources are scarce. SHA-3 plays a central role also in post-quantum cryptog raphy schemes. The design is device-agnostic and fully compliant with various FPGA platforms. XIP3030C offers high level of implementation security and is fully protected against timing attacks as its execution time does not depend on the values of the inputs.

The interface of XIP3030C is pin-wise compatible with XIP3030H, the high-speed versatile SHA-3 core with the same functionalities. The only differences are in performance (latency) and resource requirements. XIP3030C has been designed for easy integration with FPGA- and ASIC based designs in a vendor-agnostic design methodology, and the functionality of XIP3030C does not rely on any FPGA manufacturer-specific features.

• Minimal Resource Requirements: XIP3030C requires 1394 ALMs with Altera Cyclone® 10 LP or 1003 6-input LUTs with AMD Zynq-7000® and use only some internal memory blocks in a typical FPGA implementation.
• Versatile Algorithm Support: XIP3030C supports SHA-3-224/256/384/512, SHAKE-128/256, and cSHAKE-128/256. That is, XIP3030C covers all algorithms defined in [1] and also all algorithms included in [2] are supported via cSHAKE.
• Secure Architecture: The execution time of XIP3030C is independent of the input values and, consequently, provides full protection against timing-based side-channel attacks.
