And, in order to decode the message, the private keys, 7 and 11, would have to be known (of course, this would be a bad choice, the key, how the factor of 77 is trivial). The public key can be required for the subsequent encryption and published while the private key must be possessed only by the recipient of the message. But a solution is already have to wait long, and the factorization problem is practically insoluble..

  • By adding redundancies, for example, the repetition of the last 64 bits, the system can be made to produce a single root.
  • It has the disadvantage that each output of the Rabin function can be generated by each of the four possible inputs; if each output is a ciphertext, extra complexity is required to identify in decoding which of the four possible inputs was the true plaintext.
  • For a composite r (that is, like the Rabin algorithm’s ) there are no known efficient method for finding m is.

If this technique is applied, fails the proof of the equivalence with the factorization problem, so it is uncertain as of 2004 if this variant is secure.

DECRYPTIONOF RABIN CRYPTOSYSTEM To decrypt the cipher text, the private keys are necessary. This is in contradiction with this specific chosen-ciphertext attack, which has been produced since the decryption algorithm, only the root, the attacker already knows. ENCRYPTION, RABIN CRYPTOSYSTEM, All of t he pub lic k ey cryp tos yste ms h ave a p ubli c and p riva te button. If, however, (such as p and q in the Rabin algorithm), the Chinese remainder set can be applied to solve for m. This makes the Rabin-cryptos ystem and H-Rabin cryptosystems are more secure in this way than the RSA. The Handbook of Applied Cryptography of Menezes, Oorschot and Vanstone part of this equivalence, however, probably, as long as the search of the roots remains a two-process (1. As soon as the message reaches the destination, it must be decrypted (Rabin, 2014).

This is in contradiction with the chosen-ciphertext attack, which has been produced since the decryption algorithm, only the root, the attacker already knows. This would m ake the safety of H – Rabin cryptosystem is better than Rabin cryptosystem, the decryption wo uld be more compli cated than Rabin cryptosystem.. T from, out t hree private keys using the Prime factorization is much more harder than figuring two keys. 4. The most important difference is the fact that it will prove possible, in order that the pr PR roblem of the Rabin cryptosystem and H-Rabin cr yptosystem is not as hard as the integer factorization, while hardness of solving the RSA-pr PR roblem is possible to refer to the hardness of factoring (Arpit and Mathur, 2013; Haraty et al., 2006). This is the major disadvantage of the Rabin cryptosystem and is one of the factors that have prevented it from finding widespread practical application. 3. It is possible to choose plaintexts with special structures, or add padding, to eliminate this problem. I suggest that you read and study, the paper with the title Design of the Rabin-Like cryptosystem Fail without decryption, which is publicly available via the following URL. This study suggests a modification of Rabin cryptosystem that can make the cryptosystem more immune against some attacks. this shows that the solution of the system of r congruences is unique modulo m.

  • I n terms of co mputational performance, Rabin encryption is extremely fast while decryption, using the Chinese remainder set is about the same speed as RSA decryption.
  • T for this purpose, this study proposes a modification of the Rabin cryptosystem, called H – Rabin cryptosystem that can make the Rabin cryptosystem more immune against some attacks than before.

To explain some basic mathematical concepts, and it compares finally, the H-Rabin cryptosystem RSA cryptosystem and Rabin cryptosystem in terms of security and efficiency.
