Ron Rivest, Adi Shamir and Len Adlemen developed the method called as RSA algorithm. • 2. Most popular and proven asymmetric key cryptography algorithm • 3. Based on the mathematical fact that it is easy to find and multiply large prime numbers together, but it is extremely difficult to factor their product. • RSA Algorithm Steps - • 1. Choose two large prime numbers P and Q. • 2. Calculate N = P * Q • 3. Select the public key (i.e. the encryption key) E such that it is not a factor of [(P – 1) * (Q – 1)]. • 4. Select the private key (i.e. the decryption key) D such that the following equation is true: • (D * E) mod (P – 1) * (Q – 1) = 1 • 5. For encryption calculate the cipher text CT from the plain text PT as follows: CT= PT^E mod N • 6. Send CT as the cipher text to the receiver • 7. For decryption calculate the plain text PT from the cipher text CT as follows: PT = CT^D mod N • Complete Network Security / Information Security Playlist - • Network Security - Basic Concepts Def... • Download my FREE Network Security Android App - https://play.google.com/store/apps/de... • Simple Snippets Official Website - • http://simplesnippets.tech/ • Simple Snippets on Facebook - • / simplesnippets • Simple Snippets on Instagram - • / simplesnippets • Simple Snippets on Twitter - • / simplesnippet • Simple Snippets Google Plus Page - • https://plus.google.com/+SimpleSnippets • Simple Snippets email ID - • [email protected] • For More Technology News, Latest Updates and Blog articles visit our Official Website - http://simplesnippets.tech/ • #RSA #RSAalgorithm #NetworkSecurity #AsymmetricCryptography
