Cryptography and Network Security final 2024 with 100% correct answers
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.
