Introduction to Cryptography - C839 Unit 3: Number Theory and Asymmetric Cryptography updatedAsymmetric Cryptography ○ Cryptographic systems that use key pairs which consist of a public key and private key § The public key is made public( for example by publishing it in a directory) and the private key is kept secret. § does not involve exchanging a secret key. § The public key can be used to encrypt messages and only the recipient's private key can decrypt them. Disadvantag...

Distinguish between symmetric-key and asymmetric-key cryptosystems. Answer - Aysmmetric key cryptography utilizes two separate keys, a public and a private key, as opposed to symmetric key cryptography, which only utilizes one key. While encryption and decryption in symmetric key cryptography is based on substitutions and permutations of symbols, encryption in asymmetric key cryptography is based off of applying mathematical functions to numbers. Distinguish between public and private keys i...
