RSA Attacks - University of Tennessee at Chattanooga

RSA Attacks By Abdulaziz Alrasheed and Fatima Introduction Invented by Ron Rivest Adi Shamir and Len Adleman [1] the RSA cryptosystem was first revealed in the August 1977 issue of Scientific American The RSA is most commonly used for providing privacy and ensuring authenticity of digital data RSA is used by many commercial systems

Lecture 12: Public-Key Cryptography and the RSA Algorithm

(RSA) ALGORITHM FOR PUBLIC-KEY CRYPTOGRAPHY — THE BASIC IDEA The RSA algorithm is named after Ron Rivest Adi Shamir and Leonard Adleman The public-key cryptography that was made possible by this algorithm was foundational to the e-commerce revolution that followed The starting point for learning the RSA algorithm is Euler’s

Are there any attacks on RSA that take longer than this?

Attacks on RSA that take longer than thistime bound are not interesting. These include at-tacks such as an exhaustive search for Mandsome older attacks published right after the ini-tial publication of RSA.Our objective is to survey attacks on RSA thatdecrypt messages without directly factoring theRSA modulus N.

Is improper use of RSA dangerous?

Although twenty years of research haveled to a number of fascinating attacks, none ofthem is devastating. They mostly illustrate thedangers of improper use of RSA. Indeed, securelyimplementing RSA is a nontrivial task. Our goal isto survey some of these attacks and describe theunderlying mathematical tools they use.

What is the first attack on an RSA public key?

The first attack on an RSA public key hN;eito con-sider is factoring the modulus N. Given the fac-torization of N, an attacker can easily construct 2A source that explains semantic security and gives ex-amples of semantically secure ciphers is . '(N), from which the decryption exponentd=e?1mod'(N) can be found.

Is FAC-toring the modulus a brute-force attack on RSA?

We refer to fac-toring the modulus as a brute-force attackon RSA.Although factoring algorithms have been steadilyimproving, the current state of the art is still farfrom posing a threat to the security of RSA whenRSA is used properly.
