BIKE is a key encapsulation mechanism that entered the third round of NIST post-quantum cryptography standardization process. This paper presents two constant-time implementations for BIKE, one tailored Intel Haswell and ARM Cortex-M4. Our implementation much faster than avx2 written by team: bikel1, level-1 parameter set, we achieve 1.39x speedup decapsulation (which slowest operation) 1.33x s...

This report presents the results of the Differential Fault Analysis (DFA) Project. The project was funded by Secure Business Austria (SBA) and A-SIT. Its objective was to perform basic steps in the field of fault injection. The effect of faults was investigated in theory as well as in practice. The first part of this report concentrates on theoretical fault models. New fault attacks on public k...

The bacterial enzyme which decomposes the purified capsular polysaccharide of Type III Pneumococcus in vitro also destroys the capsules of the living organisms growing in media and in the animal body. Potent preparations of this same enzyme protect mice against infection with virulent Type III Pneumococcus. The protective action is type-specific. The protective activity of the specific enzyme i...

Carrier-grade networks have often multiple layers of protocols. To tackle this heterogeneity, the Pseudo-Wire architecture provides encapsulation and decapsulation functions of protocols over PacketSwitched Networks. At the scale of multi-domain networks, computing a path to support an end-to-end service requires various encapsulations and decapsulations that can be nested but for which manual ...

We first identified genes differentially expressed in rodent testis by comparing total testis, (TT; gonads whose tunica was removed by decapsulation) and isolated seminiferous tubules (TU; lacking the interstitial cells) to enriched populations of Sertoli cells (SE), spermatogonia (SG), pachytene spermatocytes (SC) and round spermatids (ST). Chondrocytes (CC) and vascular smooth muscle (SM) sam...

Abstract We present a novel full hardware implementation of Streamlined NTRU Prime, with two variants: high-speed, high-area and slower, low-area implementation. introduce several new techniques that improve performance, including batch inversion for key generation, high-speed schoolbook polynomial multiplier, an NTT multiplier combined CRT map, DSP-free modular reduction method, radix sorting ...

BIKE is a code-based key encapsulation mechanism (KEM) that was recently selected as an alternate candidate by the NIST’s standardization process on post-quantum cryptography. This KEM based Niederreiter scheme instantiated with QC-MDPC codes, and it uses BGF decoder for decapsulation. We discovered important limitations of we describe in detail, then propose new decoding algorithm codes called...
