RSA Algorithm is the example for Public Key Encryption algorithm. Here we are supposed to find two keys 1) Public Key which is used at encryption 2) Private Key which is used at decryption step 1: Select two large Primes P , Q Step 2: Calculate n=P*Q & O(n) = (P-1)*(Q-1) Step 3: Assume e and d (Public and Private Key). Step 4: Encrypt the Plain Text using Public Key e. Step 5: Decrypt the Cipher Text using Private Key d.

Information Security 3 Public Key Cryptography: An Introduction

Get Full Course: http://www.engineeringmentor.com/CNYTv3 Networks #3: This tutorial introduces the Cryptography basics. It also explains what is Encryption and Decryption. a) Cryptography basics (00:21):http://youtu.be/BEb_AnPWPwY?t=21s how do we provide this security during transmission? Well, One way of ensuring security can be use of CRYPTOGRAPHY! Cryptography is a field of network security which deals with hiding "real" infromation when it is under transmission between the two parties. Usually, the real information is transformed or hidden into another message and transmitted over the network. This transformed message in itself will make no sense even if any hacker gets hold of this information. When it reaches the destination, the receipent will know a method to de-transform the garbage message into the original information which the sender had sent.method of transforming message at sender's side and de transforming at reciever's side forms the basic model of Cryptography. b) Encryption and Decryption (3:57):http://youtu.be/BEb_AnPWPwY?t=3m57s First, the information to be transmitted, called as plain text(or message) is fed to an Encryption system. The Encyrption system uses a key to convert the plain text to encyrpted form which looks like garbage value. This is also called as cipher text. A corresponding key is used at the other end to decrypt the cipher text back to original message. When we say a key, it actually means a piece of string value which is fed to encyprtion and decryption algorithms along with the text for transformation. When the message reaches the destination, this system at the other end decrypts the cipher text into original message with the help of the key. This is called as Decryption System. The output of the Decryption System is the intended message. Depending on how the keys are shared, we can classify crytography as symmetric and asymmetric. If the keys used by both parties are same, then it is called symmetric key cryptography, or private key cryptography. If both parties use different keys for encyrption and decryption, then it is called asymmetric key cryptography or public key cryptography. video URL : https://www.youtube.com/watch?v=BEb_AnPWPwY Watch ALL CN VIDEOS: https://www.youtube.com/playlist?list=PL9OIoIp8YySF4mkIihOb_j2HZIRIlYuEx For more, visit http://www.EngineeringMentor.com Facebook: https://www.facebook.com/EngineeringMentor Twitter : https://twitter.com/Engi_Mentor

Public-key cryptography, also known as asymmetric cryptography, is a class of cryptographic algorithms which require two separate keys, one of which is secret and one of which is public. Although different, the two parts of this key pair are mathematically linked. The public key is used to encrypt plaintext or to verify a digital signature; whereas the private key is used to decrypt ciphertext or to create a digital signature. The term "asymmetric" stems from the use of different keys to perform these opposite functions, each the inverse of the other -- as contrasted with conventional cryptography which relies on the same key to perform both.
