INFORMATION SYSTEMS AND SECURITY AUDIT 1. Define the following terms: (6 Marks) -Integrity In information security‚ integrity means that data cannot be modified undetectably. This is not the same thing as referential integrity in databases‚ although it can be viewed as a special case of Consistency as understood in the classic ACID model of transaction processing. Integrity is violated when a message is actively modified in transit. Information security systems typically provide message integrity

combined with a private key derived from the public key‚ can be used to effectively encrypt messages and digital signatures Private Key: Public-key cryptography refers to a cryptographic system requiring two separate keys‚ one to lock or encrypt the plaintext‚ and one to unlock or decrypt the cyphertext. Neither key will do both functions. One of these keys is published or public and the other is kept private. Handshaking: The process by which two devices initiate communications. Handshaking begins

algorithm) is been made into a synthesizable using Verilog code which can be easily implemented on to FPGA. The algorithm is composed of three main parts: cipher‚ inverse cipher and Key Expansion. Cipher converts data to an unintelligible form called plaintext. Key Expansion generates a Key schedule that is used in cipher and inverse cipher procedure. Cipher and inverse cipher are composed of special number of rounds. For the AES algorithm‚ the number of rounds to be performed during the execution of the
