IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThis paper presents a dedicated hardware implementation of the LEDAcrypt cryptosystem, which uses Quasi-Cyclic Low-Density Parity-Check codes and the Q decoder for the decryption function. The designed architecture is synthesized for both FPGA and ASIC technologies, featuring an intrinsic scalability over a wide range of parallelism degrees, which makes it possible to target multiple application scenarios, with different trade-offs between decryption latency and implementation complexity. The proposed system achieves a large speed-up over both software execution and a previous hardware implementation, with a the decryption latency as low as 3.16 ms for the FPGA version, and 1.2 ms when synthesized for a 65 nm CMOS technology.
