Abstract: In this work, we present the design and implementation of a hardware accelerator for AES encryption and decryption using AMD Vitis HLS and Xilinx Vivado. The primary objective of this work ...
GEM is a block cipher mode similar to Galois/Counter Mode but with the following enhancements: Nonces are now longer than 96-bit. AES-256-GEM uses 256-bit nonces, while AES-128-GEM uses 192-bit nonces ...
