Cryptology

Cryptology is the science of data that is  static or in transit, and the using of a cipher to keep its true meaning hidden. 

Cryptography is the study of techniques and principles of concealment of information by way of a cipher.  

Cryptanalysis is the art of deciphering or forging  encrypted information with out a key.  Creating and breaking ciphers is common place in the area of research.

Cryptography has been around since the dawn of man.  Ciphers have been employed in the highest echelons of society, as well as the most secret of occult societies, and fraternal brotherhoods.  Ciphers historically have been used by military generals to get messages behind enemy lines or to relay information to future generations as seen in hieroglyphs.  In a more modern era, today presently cipher have been used to encode information that is in transit or at rest in a storage device.  Encryption is used to keep all of our data safe in the cyber world.   There is a need for cybersecurity cryptologists, and will be a greater need as the cyberspace grows.

In fact, he had constant assassination attempts from people whom he knew intimately.  Caesar was known to use several ciphers in his communications.
