Asymmetric Encryption | Public Key Encryption | RSA Encryption Algorithm | DSS | ECC | IS Lec 6

Asymmetric cryptography also called public key encryption.Public-key algorithms are based on mathematical functions rather than on simple operations on bit patterns.Public-key cryptography is involving the use of two separate keys while symmetric encryption uses only one key we can access Confidentiality Key distribution Authentication from public key encryption.in this lecture we discuss different algorithms of a symmetric encryption RSA , Diffie–Hellman key exchange ,Digital Signature Standard (DSS) Elliptic Curve Cryptography (ECC). (Ron Rivest, Adi Shamir, and Len Adleman ) developed in 1977 at MIT Most widely used Public Key Encryption Algorithm RSA is a block cipher in which the plaintext and ciphertext are integers between 0 and n – 1 for some n. 1024-bit key size (about 300 decimal digits) is considered strong enough for virtually all applications. RSA Steps:Key Generation, Encryption ,Decryption. in this lecture we also discuss Diffie–Hellman Key Exchange Algorithm. Enable two users to securely reach agreement about a shared secret that can be used as a secret key for subsequent symmetric encryption of messages.we also discuss Digital Signature Standard DSS. we also discuss Elliptic Curve Cryptography (ECC)..i hope you will understand these lectures remember us in your prayer stay connected us through "techno learn" jeety rho khush rho
