Provides means for secure key exchange over insecure channel. RSA ALGORITHM 1. Some unanswered questions on symmetric cryptosystems • Key management: changing the secret key or establishing one is nontrivial – Change the keys two users share (should be done reasonably often) – Establish a secret key with somebody you do not know and cannot meet in person: (e.g., visiting … try all possible private keys. A problem can be solved in polynomial time. Category: Tags: rsa | cryptography | key | public. Trudy/Eve/Mallory. If Fermat's Little Theorem fails, then n is composite. but the calculation of the inverse is infeasible. Deciphering the enciphered form of a message M yields M. D(E(M)) = M Both E and D are easy to compute By publicly revealing E, the user does not reveal an easy way to compute D (One-Way Functions) If a message M is first deciphered and then enciphered, M is the result E(D(M)) = M RSA is an algorithm for public-key cryptography 8 - public key cryptography radically different approach ...

John Nguyen RSA as a Digital Signature Algorithm The need for digital signature: online banking, routable forms… Requirement: something uniquely identify oneself, and people can verify that unique identification. A special attention will be given to the problem of factorization of integers that play such an important role for security of RSA. Presentation Explaining RSA The concept of public-key cryptography. Three possible approaches to attacking the RSA. Each user has a pair of keys a public key and a, Invented by Whitfield Diffie Martin Hellman, A problem described in an ancient Chinese, Problem We have a number of things, but we do, A user wishing to set up an RSA cryptosystem.
