An Efficient Public Key Encryption Scheme Based on QC-MDPC Lattices

IEEE Access, 2017
In this paper, we introduce a new family of lattices, namely QC-MDPC lattices, which are a special case of LDPC lattices, and an improved bit flipping algorithm for decoding of these lattices. Encoding and decoding implementations of QC-MDPC lattices are

Computation of private key for LUC cryptosystem [PDF]

, 2009
LUC cryptosystem is a public key cryptosystem based on Lucas functions. The encryption of this cryptosystem is relatively easy since we have the knowledge of public key e, two primes p and q and also the message M.

Cryptanalysis of a Homomorphic Public-Key

, 2006
The paper cryptanalyses a public-key cryptosystem recently proposed by Grigoriev and Ponomarenko, which encrypts an element from a fixed finite group defined in terms of generators and relations to produce a ciphertext from SL(2, Z).

Private Key Extension of Polly Cracker Cryptosystems [PDF]

Computer Science Journal of Moldova, 2008
In 1993 Koblitz and Fellows proposed a public key cryptosystem, Polly Cracker, based on the problem of solving multivariate systems of polynomial equations, which was soon generalized to a Dröbner basis formulation.

Break Finite Automata Public Key Cryptosystem

, 1995
. In this paper we break a 10-year's standing public key cryptosystem, Finite Automata Public Key Cryptosystem(FAPKC for short). The security of FAPKC was mainly based on the difficulty of finding a special common left factor of two given matrix ...

The Use of Fractions in Public-Key Cryptosystems [PDF]

, 2007
This paper discusses an asymmetric cryptosystem based on fractions, the Rk-system, which can be implemented fast using only additions and multiplications. Also it is very simple to initialize the system and to generate new keys. The Rk-system makes use of the difficulty to compute the numerator and the denumerator of a fraction only knowing the rounded

PUBLIC-KEY CRYPTOSYSTEM BASED ON ISOGENIES

, 2008
. A new general mathematical problem, suitable for publickey cryptosystems, is proposed: morphism computation in a category of Abelian groups. In connection with elliptic curves over finite fields, the problem becomes the following: compute an isogeny ...
