A single instance of the ASCON-F IP core can encrypt or decrypt data using the Ascon-128 and Ascon-128a functions or perform Cryptographic hashing Hash per the Ascon-Hash and Ascon-Hasha functions. The mode of operation (encryption or decryption, and Ascon function), as well as the encryption key and nonce values, are run-time programmable and can be changed per block of input data. The core uses simple input and output interfaces, that can be optionally bridged to AXI4-Stream, or to AXI4 Memory Mapped master or slave ports using bridges separately available from CAST. The core synthesizes to approximately 11k gates and is able to run at frequencies exceeding 2 GHz in modern ASIC technologies. Ignoring overheads related to input padding and core initialization, the throughput ranges from 5.3 to 16 bits/cycle depending on the mode and function, which at 2 GHz translates to 10.6 to 32 Gbps. The processing throughput can be further scaled by instantiating the core multiple times. The core is designed for ease of use and integration and adheres to industry-best coding and verification practices. Technology mapping and timing closure are trouble-free, as the core contains no multi-cycle or false paths and uses only rising-edge-triggered D-type flip-flops, no tri-states, no SRAMs, and a single-clock/reset domain.

A single instance supports encryption & decryption with Ascon-128 & Ascon-128a, as well as cryptographic hashing with Ascon-Hash & Ascon-Hasha. Operation mode, key, and nonce values are run-time programmable & can change per input block. The core provides simple I/O I/F, optionally bridged to AXI4-Stream or AXI4 Memory Mapped ports through CAST bridges. It synthesizes to ~11k gates & runs at over 2GHz in modern ASIC technologies. Excluding padding & initialization, throughput ranges from 5.3 to 16 bits/cycle, or 10.6 to 32Gbps at 2GHz, with higher throughput possible by instantiating multiple cores. Easy to use & integrate, following best coding & verification practices, has no multi-cycle or false paths, uses only rising-edge D flip-flops, no tri-states or SRAMs, and operates in a single clock/reset domain.
