Poly-Dragon: an efficient multivariate public key cryptosystem
In this paper we propose an efficient multivariate public key cryptosystem. Public key of our cryptosystem contains polynomials of total degree three in plaintext and ciphertext variables, two in plaintext variables and one in ciphertext variables. However, it is possible to reduce the public key size by writing it as two sets of quadratic multivariate polynomials. The complexity of encryption ...
متن کاملLittle Dragon Two: An efficient Multivariate Public Key Cryptosystem
In 1998 [8], Patarin proposed an efficient cryptosystem called Little Dragon which was a variant a variant of Matsumoto Imai cryptosystem C*. However Patarin latter found that Little Dragon cryptosystem is not secure [8], [3]. In this paper we propose a cryptosystem Little Dragon Two which is as efficient as Little Dragon cryptosystem but secure against all the known attacks. Like Little Dragon...
متن کاملAn efficient VLSI architecture for RSA public-key cryptosystem
In this paper, a new efficient VLSI archtecture to compute RSA public-key cryptosystem is proposed. The modified H-algorithm is applied to fmd the modular exponentiation. By this modified Halgorithm, the modular multiplication steps reduced about 5dl8. For the modular multiplication the L-algorithm (LSB first) is used. In the architecture of the modular multiplication the iteration times are on...
متن کاملAn efficient probabilistic public-key cryptosystem over quadratic fields quotients
We present a new probabilistic cryptosystem working in quadratic fields quotients. Computation in such objects can be done efficiently with Lucas sequences which help to design a fast system. The security of the scheme is based on the LUC problem and its semantic security on a new decisional problem. This system appears to be an alternative to schemes based on the RSA primitive and has a full c...
متن کاملPec - an Alternate and More Efficient Public Key Cryptosystem
In an increasingly connected world, security is a top concern for Internet of Things (IoT). These IoT devices have to be inexpensive implying that they will be constrained in storage and computing resources. In order to secure such devices, highly efficient public key cryptosystems (PKC) are critical. Elliptic Curve Cryptography (ECC) is the most commonly implemented PKC in use today. In this p...
