Breaking RSA encryption is known as the RSA problem. Whether it is as difficult as the factoring problem is an open question. [3] There are no published methods to defeat the system if a large enough key is used. RSA is a relatively slow algorithm. Because of this, it is not commonly used to directly encrypt user data.
Breaking RSA Generically is Equivalent to Factoring, D. Aggarwal and U. Maurer, 2008. This Eurocrypt 2009 paper (link is to a preprint version) proves that solving the RSA problem using a generic ring algorithm is as difficult as factoring. When e-th Roots Become Easier Than Factoring, Antoine Joux, David Naccache and Emmanuel Thomé, 2007 ...
It provides the basic definitions of and recommendations for implementing the RSA algorithm for public-key cryptography. It defines the mathematical properties of public and private keys, primitive operations for encryption and signatures, secure cryptographic schemes, and related ASN.1 syntax representations. The current version is 2.2 (2012 ...
RSA (Rivest–Shamir–Adleman) is another notable public-key cryptosystem. Created in 1978, it is still used today for applications involving digital signatures. [18] Using number theory, the RSA algorithm selects two prime numbers, which help generate both the encryption and decryption keys. [19]
Some special and specific algorithms have been developed to aid in attacking some public key encryption algorithms; both RSA and ElGamal encryption have known attacks that are much faster than the brute-force approach. [citation needed] None of these are sufficiently improved to be actually practical, however.
The OAEP algorithm is a form of Feistel network which uses a pair of random oracles G and H to process the plaintext prior to asymmetric encryption. When combined with any secure trapdoor one-way permutation f {\displaystyle f} , this processing is proved in the random oracle model to result in a combined scheme which is semantically secure ...

A deterministic encryption scheme (as opposed to a probabilistic encryption scheme) is a cryptosystem which always produces the same ciphertext for a given plaintext and key, even over separate executions of the encryption algorithm.
