It was known as the first polyalphabetic cipher, made out of two circular metals that have mixed alphabets and attached to one pin. The leather strip is then unwound and sent out without the stick so the message cannot be read while in transit.ġ467: The Alberti Cipher was invented by Leon Battista Alberti. This was the first cryptography using only a wooden stick! Spartans who send and receive information both have the same kind of rod where a strip of leather would be wrapped around it. The frequency analysis technique was made by the Arab mathematician, Al-Kindi to break the code.ħ00 BC: The Greeks used Skytale. By now, we know this process as encryption and can publicly be added in any data file using two inventions in the 1970’s – Public-key cryptography and Data Encryption Standard.įor more curious minds, here’s a detailed but bulleted version about encryption and how it came about.ġ900 BC: In the old kingdom of Egypt, hieroglyphs were used and carved to the walls of their tombsĨ00BC: Monoalphabetic substitution ciphers were used. As time went by, of course, cryptography also grew, developed and changed which in the 20 th century began growing with the introduction of electronics. Basically, kryptos, or later on known as cryptography is creating a secret message that the public cannot easily understand. Back then, computers we’re non-existent so securing information required skills and techniques that need to be studied. If you would like to know where it all began, encryption can be found as early as the ancient Greek times where the term “encryption” was known as “kryptos” which literally means hidden secret. To encrypt a file these days doesn’t require supercomputers or spy kits, in fact adding a password is just as easy as 1,2,3… When we say encryption, it is keeping information secret by providing limited access or putting passwords. Encryption, protection, passwords – these all help us in keeping data safe whether we’re making an online transaction or sending a file.
