This is a continuing part of our series on forensic accounting. Within this segment we discuss the concepts that are part of computer forensics known as cryptology. The term cryptography is from Ancient Greek and means “hidden secret”. It is the practice and study of techniques for secure communications in the presence of adversarial behavior. Cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages. Cryptography starts with secrets. Various aspects in information security such as data confidentiality, data integrity, authentication and non-repudiation (where a statement’s author cannot successfully dispute its authorship) are central to modern cryptography.
