Homomorphic public-key cryptosystems and encrypting boolean circuits
, 2003 In this paper homomorphic cryptosystems are designed for the first time over any finite group. Applying Barrington's construction we produce for any boolean circuit of the logarithmic depth its encrypted simulation of a polynomial size over an ...

A Modified and Secured RSA Public Key Cryptosystem Based on “n” Prime Numbers
, 2018 Cryptography is the study that provides security service. It concerns with confidentiality, integrity, and authentication. Public key cryptography provides an enormous revolution in the field of the cryptosystem. It uses two different keys where keys are

Hidden Polynomial(s) Cryptosystems
, 2003 We propose variations of the class of hidden monomial cryptosystems in order to make it resistant to all known attacks. We use identities built upon a single bivariate polynomial equation with coefficients in a finite field. Indeed, it can be replaced by a ``small'' ideal, as well. Throughout, we set up probabilistic encryption protocols, too. The same

A Distinguisher-Based Attack on a Variant of McEliece's Cryptosystem Based on Reed-Solomon Codes
, 2012 Baldi et \textit{al.} proposed a variant of McEliece's cryptosystem. The main idea is to replace its permutation matrix by adding to it a rank 1 matrix.

Asymmetric Cryptosystem Using Improved Equal Modulus Decomposition in Cylindrical Diffraction Domain
IEEE Access, 2019 We present a simple and efficient asymmetric cryptosystem using an improved equal modulus decomposition (EMD) in the cylindrical diffraction domain. Being different from a cryptosystem based on the conventional EMD, whose outputs are complex-valued, in ...

Bulletin of Electrical Engineering and Informatics, 2015 This paper, we introduce mainly the concept of beta cryptosystem, whose security is based on generalized discrete logarithm problem and integer factorization problem in the multiplicative group of finite fields. We show that the proposed public key cryptosystem based on generalized discrete logarithm problem and integer factorization problem, provides ...
