Your encryption system is thus only as strong as your cryptographic key is unpredictable. Those random numbers are a cryptographic key, which unlocks the content of the encrypted message, but it’s useless for deciphering other messages, just as your house key opens your front door but not your neighbor’s. To recover the original message, you need to know the specific sequence of random numbers the algorithm used to encrypt the message. Despite its relatively simple algorithm, the one-time pad becomes unbreakable with the addition of random numbers.
That’s why we combine the algorithm with random numbers. An encrypted message will be completely exposed to anyone who knows the algorithm used to secure it. You cannot protect a message with the first ingredient alone, no matter how good the algorithm is. And finally, you need the means to deliver the first two ingredients to the intended recipient without anyone else gaining access. Second, you need a way to produce random numbers. First, you need an algorithm that converts your message into a string of meaningless characters. Illustration: Erik VrielinkĪs any cryptographer knows, you need three ingredients to make a hackproof encryption method. Unfortunately, most one-time pads today use algorithms to generate pseudorandom numbers, like this example, which used numbers generated by Google. You can’t beat one-time pads for security, if you use truly random numbers to shift the letters. And that means we’re finally getting close to solving one of cryptography’s biggest puzzles and realizing the unbreakable encryption envisioned by Miller so many years ago. By measuring the unpredictable attributes of subatomic particles, these devices can use the rules of quantum mechanics to encrypt messages. “Surprising no one, 2017 marked another ‘worst year ever’ in personal data breaches and cyber incidents around the world,” the report concluded.įortunately, researchers have made good progress in recent years in developing technologies that can generate and distribute truly random numbers. In just one of those attacks, on the consumer credit reporting company Equifax, hackers culled the personal information of nearly 148 million customers.
According to the 2017 “ Cyber Incident & Breach Trends Report” by the Online Trust Alliance, more than 150,000 businesses and government institutions were the victims of cybercrime last year. And compared with Miller’s day, today we have more ways of connecting than the telegraph-through Internet of Things devices, wearable tech, and blockchain-dependent services, to name just a few-and they all need strong encryption.

So instead, we’ve relied on less secure encryption methods, with the consequence that attackers who are sufficiently patient and knowledgeable can now crack into any encrypted data they want. That, it turns out, is incredibly hard to do. And ever since, cryptographers have tried to devise a way to generate and distribute the unique and truly random numbers that the technique requires. Joseph Mauborgne came out with essentially the same idea, which they called the one-time pad. For truly unbreakable encryption, each string of random numbers would encode only one message before being discarded.Ībout 35 years after Miller’s book, Bell Labs engineer Gilbert S. Even a meddlesome cable operator wouldn’t know what to make of MHNT unless he also had the list of random numbers, 5-3-2-4.
For example, to encode the word HELP, you might shift the H by 5 so that it became an M, the E by 3 so that it became an H, the L by 2 so that it became an N, and the P by 4 so that it became a T. In his own book on telegraphic code, published in 1882, Miller proposed encrypting messages by shifting each letter in the message by a random number of places, resulting in a string of gibberish. As a contemporary, Robert Slater, the secretary of the French Atlantic Telegraph Co., wrote in his 1870 book Telegraphic Code, to Ensure Secresy in the Trans mission of Telegrams, “Nothing then is easier for a dishonest cable operator than the commission of a fraud of gigantic extent.”
Sometime later, he grew interested in telegraphy and especially the challenge of preventing fraud by wire-a problem that was frustrating many bankers at the time. Miller had learned about cryptography while serving as a military investigator during the U.S. Nearly 140 years later, cryptographers have yet to come up with something better. In 1882, a banker in Sacramento, Calif., named Frank Miller developed an absolutely unbreakable encryption method.
