Computing HNF has a long history, but designing a storage efficient algorithm is a challenging issue for matrices of large sizes. One of the main challenges in the design of storage efficient HNF algorithm is to control the rank and the size of the i

In LATTE, a lattice based hierarchical identity-based encryption (HIBE) scheme, each hierarchical level user delegates a trapdoor basis to the next level by solving a generalized NTRU equation of level ℓ ≥ 3. For ℓ = 2, Howgrave-Graham, Pipher,

In this paper, we present a refinement of the Cipolla–Lehmer type algorithm given by H. C. Williams in 1972, and later improved by K. S. Williams and K. Hardy in 1993. For a given r-th power residue $$c\in \mathbb {F}_q$$ where r is an odd prime, t

We study algorithms that can efficiently find cube roots by modifying Cipolla-Lehmer algorithm. In this paper, we present two type algorithms for finding cube roots in finite field, which improves Cipolla-Lehmer algorithm. If the number of multiplica

The general number field sieve (GNFS) is asymptotically the fastest known factoring algorithm. One of the most important steps of GNFS is to select a good polynomial pair. A standard way of polynomial selection (being used in factoring RSA challenge

We present an $r$ -th root extraction algorithm over a finite field $\mathbb {F}_q$ . Our algorithm precomputes a primitive $r^s$ -th root of unity $\xi$ where $s$ is the largest positive integer satisfying $r^s| q-1$ , and is applicable for the case

Let p be a prime such that p ≡ 1 ( mod 3 ) . Let c be a cubic residue ( mod p ) such that c p − 1 3 ≡ 1 ( mod p ) . In this paper, we present a refinement of Muller's algorithm for computing a cube root of c [11] , which also improves Williams'

In this paper, we present a new cube root algorithm in the finite field $$\mathbb {F}_{q}$$ F q with $$q$$ q a power of prime, which extends the Cipolla---Lehmer type algorithms (Cipolla, Un metodo per la risolutione della congruenza di secondo grado

We study an algorithm that can efficiently find square roots and cube roots by modifying Tonelli-Shanks algorithm, which has an application in Number Field Sieve (NFS). The Number Field Sieve, the fastest known factoring algorithm, is a powerful tool
