A computer crime is defined as any form of crime that involves a network and a computer. Early computer crimes often involved physical damage to computer systems and subversion of the long-distance telephone networks. The earlier periods, 1960s and 1970s, were not common with computer crimes. Actually, the incidents were mere pranks played on the computer systems. There were also few laws against such activities and that is the reason why they were never viewed as crimes. This paper therefore discusses the history and origins of computer crime.
According to Kabay (2008), computer crime began as early as the 1870s ...

Introduction

Cryptography is a mathematical technique for encrypting and decrypting data. Cryptography enables one to store and transmit sensitive information across public insecure networks so that no one else can access the information apart from the authorized persons, i.e., the sender and the intended recipient (Martin, 2012). Cryptography uses a cryptographic algorithm. A cryptographic algorithm is a mathematical function used during the encryption and decryption process. The algorithm works together with a key to transform plaintext into encrypted text. The security of encrypted information depends on two things: the secrecy of the key used and the strength of the cryptographic algorithm employed (Stallings, 2013).
