Melting SNOW-V: improved lightweight architectures

Andrea Felice Caforio, Subhadeep Banik, Muhammed Fatih Balli

SNOW-V is a stream cipher proposed by Ekdahl et al. at IACR ToSC 2019(3) with an objective to be deployed as the encryption primitive in 5G systems. The stream cipher offers 256-bit security and is ready for deployment in the post-quantum era, in which as ...

The Area-Latency Symbiosis: Towards Improved Serial Encryption Circuits

Andrea Felice Caforio, Subhadeep Banik, Muhammed Fatih Balli

The bit-sliding paper of Jean et al. (CHES 2017) showed that the smallest-size circuit for SPN based block ciphers such as AES, SKINNY and PRESENT can be achieved via bit-serial implementations. Their technique decreases the bit size of the datapath and na ...

A Study of Persistent Fault Analysis

Andrea Felice Caforio, Subhadeep Banik

Persistent faults mark a new class of injections that perturb lookup tables within block ciphers with the overall goal of recovering the encryption key. Unlike earlier fault types persistent faults remain intact over many encryptions until the affected dev ...
