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...

Definition of encryption - "Cryptography" -involves making and using codes to keep messages private and secure for their intended recipient --Kryptos = "hidden" Cryptanalysis - -involves cracking/breaking encrypted messages back into their unencrypted origins Bit Stream cipher - -encrypts plaintext one byte at a time (8-bits) -it is very fast encryption, lower hardware complexity, but can result in duplicate keystreams to encrypt and if someone gets both messages using the same key, t...
