It was later replaced by AES encryption, which I’ll discuss later. National Security Agency (NSA) to decipher messages encrypted using the standard. Some observers feared that DES included a backdoor that could be used by the U.S. In the mid-1970s, IBM created an encryption model that was adapted as the U.S. Until this development, all encryption models were designed using a symmetric key – I’ll discuss the Enigma machine later on. Perhaps the most important development in modern encryption took place in the period of 1933 to 1945, when German cryptologists created and continually improved the world-famous Enigma machine. The Middle Ages brought a rapid development of encryption types that used polyalphabetic substitution (multiple substitution alphabets used to minimize the success of decryption). In the time of Julius Caesar (100-44 B.C.), the Romans used a similar substitution, known today as the “ Caesar Shift Cipher.” Instead of reversing the alphabet, the Romans used a pre-agreed shift of the letters – only the person who knew about the agreed shift of letters could decipher the message.įor example, if the agreed shift was 5, then the sentence “This is super interesting!” would be encrypted into “YMNX NX XZUJW NSYJWJXYNSL!” That means that an “A” becomes a “Z,” “B” becomes a “Y,” etc.įor example, “Hello” would be encoded as “Svool.” Later, Hebrew scribes developed an encryption model called “ATBASH.” This type of encryption used a reversed-alphabet simple substitution code.

Without knowing the exact diameter size, a person wouldn’t be able to decipher the message (which means to convert the code into understandable text). A message could only be read by someone who had a stick of the exact same diameter. In 700 B.C., the Spartans wrote important messages on leather, which was wrapped around sticks. The word encryption comes from “kryptos.” The Greeks used “krypto” to describe something that was hidden or secret. The first documented instance of written cryptography dates back to 1900 B.C., when an Egyptian scribe used non-standard hieroglyphs in an inscription. History of EncryptionĮncryption has been in use since well before most people could read or write. Rest assured, today’s encryption uses techniques and methods that are much more powerful and secure than the ancient users’ simple character-replacement algorithms.īefore we take a look at how modern encryption works, let’s take a quick look at the history of encryption. Thousands of years ago, Greeks and Egyptians used cryptography (a form of encryption) to keep important messages safe from prying eyes. Online banking, email, online shopping – even the website you’re currently visiting – all use encryption to protect your data.Įncryption isn’t a recent creation. While you may not be aware of this, encryption already protects many of your daily online activities. One of the best ways to protect your privacy and valuable personal data on the internet? Encryption. The internet presented a new, profitable frontier for cyber criminals, which makes protecting your online privacy more important than ever. With that instant connectivity comes the rapidly increasing threat of cybercrime and other intrusions on your privacy. Computers, mobile devices and instant connections to the internet are seemingly everywhere.
