An Ultra-High Throughput AES-Based Authenticated Encryption Scheme for 6G: Design and Implementation
Andrea Felice Caforio, Subhadeep Banik
In this paper, we propose Rocca-S, an authenticated encryption scheme with a 256-bit key and a 256-bit tag targeting 6G applications bootstrapped from AES. Rocca-S achieves an encryption/decryption speed of more than 200 Gbps in the latest software environ ...
Springer International Publishing Ag2024Near Collision Attack Against Grain V1
Daniel Patrick Collins, Subhadeep Banik, Willi Meier
A near collision attack against the Grain v1 stream cipher was proposed by Zhang et al. in Eurocrypt 18. The attack uses the fact that two internal states of the stream cipher with very low hamming distance between them, produce similar keystream sequences ...
2023Bias Cancellation of MixColumns
Francesco Regazzoni, Andrea Felice Caforio, Subhadeep Banik
At COSADE'2020, Carre et al. established a novel biascancelling property of the AES MixColumns matrix that effectively corrects any skewed output distribution of a state byte due to a faulty substitution box. Consequently, any effected byte is rendered uni ...
SPRINGER INTERNATIONAL PUBLISHING AG2022Six shades lighter: a bit-serial implementation of the AES family
Subhadeep Banik, Muhammed Fatih Balli, Sergio Roldán Lombardía
Recently, cryptographic literature has seen new block cipher designs such as PRESENT, GIFT or SKINNY that aim to be more lightweight than the current standard, i.e., AES. Even though AES family of block ciphers were designed two decades ago, they still rem ...
2021Atom: A Stream Cipher with Double Key Filter
Andrea Felice Caforio, Subhadeep Banik, Willi Meier
It has been common knowledge that for a stream cipher to be secure against generic TMD tradeoff attacks, the size of its internal state in bits needs to be at least twice the size of the length of its secret key. In FSE 2015, Armknecht and Mikhalev however ...
2021Further Results on Efficient Implementations of Block Cipher Linear Layers
At the FSE conference of ToSC 2018, Kranz et al. presented their results on shortest linear programs for the linear layers of several well known block ciphers in literature. Shortest linear programs are essentially the minimum number of 2-input xor gates r ...
2021Improving First-Order Threshold Implementations of SKINNY
Andrea Felice Caforio, Daniel Patrick Collins, Subhadeep Banik, Ognjen Glamocanin
Threshold Implementations have become a popular generic technique to construct circuits resilient against power analysis attacks.In this paper, we look to devise efficient threshold circuits for the lightweight block cipher family SKINNY. The only threshol ...
Springer, Cham2021A Deeper Look at the Energy Consumption of Lightweight Block Ciphers
Francesco Regazzoni, Andrea Felice Caforio, Subhadeep Banik, Muhammed Fatih Balli
In the last few years, the field of lightweight cryptography has seen an influx in the number of block ciphers and hash functions being proposed. In the past there have been numerous papers that have looked at circuit level implementation of block ciphers ...
IEEE2021Orthros: A Low-Latency PRF
We present Orthros, a 128-bit block pseudorandom function. It is designed with primary focus on latency of fully unrolled circuits. For this purpose, we adopt a parallel structure comprising two keyed permutations. The round function of each permutation is ...
2021Complete Practical Side-Channel-Assisted Reverse Engineering of AES-Like Ciphers
Andrea Felice Caforio, Subhadeep Banik, Muhammed Fatih Balli
Public knowledge about the structure of a cryptographic system is a standard assumption in the literature and algorithms are expected to guarantee security in a setting where only the encryption key is kept secret. Nevertheless, undisclosed proprietary cry ...
