cryptology - ANSWER - science concerned with data communication and storage in secure and usually secret form. It encompasses both cryptography and cryptanalysis. cryptography - ANSWER - is the practice and study of techniques for secure communication in the presence of adversarial behavior cryptanalysis - ANSWER - The process of decrypting a message without knowing the cipher or key used to encrypt it. steganography - ANSWER - A field within cryptography; uses images to hide data. c...

Confidentiality - Only authorised people can read a message. A key is needed in order to read the message. Authentication - Only authorised people can write a message. A key is needed in order to write the message. Symmetric key cipher - KE = KD (or can easily be deduced from one another). Symmetric key cipher - Encryption and decryption keys known only to the sender and receiver. Symmetric key cipher - Requires a secure channel for transmission of the cryptographic key. Asymmetric key...

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...
