Mathematical Attacks on RSA Cryptosystem
In this paper some of the most common attacks against Rivest, Shamir, and Adleman (RSA) cryptosystem are presented. We describe the integer factoring attacks, attacks on the underlying mathematical function, as well as attacks that exploit details in implementations of the algorithm. Algorithms for each type of attacks are developed and analyzed by their complexity, memory requirements and area...
متن کاملAttack on RSA Cryptosystem
The RSA cryptosystem is most widely used cryptosystem it may be used to provide both secrecy and digital signatures and its security is based on the intractability of the integer factorization. The security of RSA algorithm depends on the ability of the hacker to factorize numbers. New, faster and better methods for factoring numbers are constantly being devised. The Trent best for long numbers...
متن کاملOptimized Security of Wireless Sensor Networks Based on a Modified Nk Cryptosystem
Security in the wireless sensor networks (WSNs) is based on using public-key cryptosystems such as RSA cryptosystem to achieve the authentication between wireless sensor nodes and their base station. This cryptosystem has two important problems; (i) the decryption process is slow (ii) it is insecure due to some known attacks such as common modulus attack and low exponent attack. In this paper w...
متن کاملNew Attacks on the RSA Cryptosystem
This paper presents three new attacks on the RSA cryptosystem. The first two attacks work when k RSA public keys (Ni, ei) are such that there exist k relations of the shape eix−yiφ(Ni) = zi or of the shape eixi − yφ(Ni) = zi where Ni = piqi, φ(Ni) = (pi − 1)(qi − 1) and the parameters x, xi, y, yi, zi are suitably small in terms of the prime factors of the moduli. We show that our attacks enabl...
متن کاملAttacks on the Rsa Cryptosystem and Some of Its Instances
Two types of attacking the RSA cryptosystem are discussed. The rst aims at a careless choice of the primes p and q, which are the basis of RSA security. Choosing these primes carefully can prevent the cryptosystem from this type of attack. The second aims at special instances of RSA-based cryptographical protocols. Speciic properties of these protocols enable users of the system or even outside...
