NTTRU: Truly Fast NTRU Using NTT
Transactions on Cryptographic Hardware and Embedded Systems, 2019 We present NTTRU – an IND-CCA2 secure NTRU-based key encapsulation scheme that uses the number theoretic transform (NTT) over the cyclotomic ring Z7681[X]/(X768−X384+1) and produces public keys and ciphertexts of approximately 1.25 KB at the 128-bit ...

SIMD Implementation of the Aho-Corasick Algorithm using Intel AVX2
Scalable Computing: Practice and Experience, 2019 The Aho-Corasick (AC) algorithm is a multiple pattern exact string-matching algorithm proposed by Alfred V. Aho and Margaret J. Corasick. It is used to locate all occurrences of a finite set of patterns within an input text simultaneously. The AC algorithm is in the heart of many applications including digital forensics such as digital signatures ...
