Kirigami takes pop-up books to a whole new level. The Japanese paper craft involves cutting patterns in paper to transform a two-dimensional sheet into an intricate, three-dimensional structure when p...
Can we Beat the Square Root Bound for ECDLP over Fp2 via Representations?
ECDLP Square Root Bound
2019/7/15
We give a 4-list algorithm for solving the Elliptic Curve Discrete Logarithm (ECDLP) over some quadratic field Fp2Fp2. Using the representation technique, we reduce ECDLP to a multivariate polynomial ...
Efficient Square-based Montgomery Multiplier for All Type C.1 Pentanomials
Montgomery multiplication Squaring Bit-parallel
2017/9/1
In this paper, we present a low complexity bit-parallel Montgomery multiplier for GF(2m)GF(2m) generated with a special class of irreducible pentanomials xm+xm−1+xk+x+1xm+xm−1+xk+x+1. Base...
We introduce a new type of Montgomery-like square root formulae in GF(2m)GF(2m) defined by an arbitrary irreducible trinomial, which is more efficient compared with classic square root operation. By c...
The square of opposition in orthomodular logic
square of opposition modal orthomodular logic classical consequences
2016/5/30
In Aristotelian logic, categorical propositions are divided in Universal Affirmative, Universal Negative, Particular Affirmative and Particular Negative. Possible relations between two of the mentione...
Kiasu-BC is a tweakable block cipher presented within the TWEAKEY framework at AsiaCrypt 2014. Kiasu-BC is almost identical to AES-128, the only difference to AES-128 is the tweak addition, where the ...
A Star-based Independent Biclique Attack on Full Rounds SQUARE
Block cipher SQUARE Biclique attack Star-based independent biclique
2016/1/27
SQUARE is an iterated block cipher proposed by Daemen et.al. in FSE1997. Inspired
by Bogdanov et.al.’s recent works [12], we first present an improved biclique attack, i.e. stat-based
independent bi...

Square Span Programs with Applications to Succinct NIZK Arguments
Square span program quadratic span program SNARKs
2016/1/7
We propose a new characterization of NP using square span
programs (SSPs). We first characterize NP as affine map constraints
on small vectors. We then relate this characterization to SSPs, which
a...
