Moore's Law law states that processor speeds, or overall processing power for computers will double every two years. They believed it would be so for around another 100 years (taking Moore’s Law into account). Until the Edward Snowden revelations, people assumed that 128-bit encryption was in practice uncrackable through brute force. The number of years required to brute force a 256-bit cipher is 3.31 x 10(56) - which is about 20000….0000 (total 46 zeros) times the age of Universe (13.5 billion or 1.35 x 10(10) years)! That’s still a long time and is the figure for breaking just one key! 256-bit keyĪ 256-bit key would require 2(128) times more computational power to break than a 128-bit one.

Almost 3 times as fast as the Fujitsu K, at 33.86 petaflops, it would "only" take it around a third of a billion years to crack a 128-bit AES key. In 2016 the most powerful supercomputer in the world was the NUDT Tianhe-2 in Guangzhou, China. Going through each of them would take thousands of operations or more to break. For a brute force attack: 128-bit keyĪ 128-bit key cipher has 3.4 x10(38) possible keys. If anyone is capable of breaking modern encryption ciphers it is the NSA, but to do so is a considerable challenge. This involves trying every possible combination to find the correct one. The crudest form of attack on a cipher is known as a brute force attack (or exhaustive key search). It is the raw number of ones and zeros used in a cipher. Key length is the crudest way of determining how long a cipher will take to break. So let’s examine the current state of play… Encryption Key Length As a result, the more encrypted data becomes standard, the less it will be singled out by agencies that don’t wish to waste their time.įollowing revelations about the scale of the NSA’s deliberate assault on global encryption standards, confidence in encryption has taken a big dent. This information will be kept indefinitely until it is cracked, but this is an incredibly lengthy process. Using encryption to protect your data can make life difficult for surveillance organizations that are tasked to decrypt it. In order to avoid the eye-in-the-sky that draws increasing similarities to George Orwell’s Big Brother, there are steps we can take. To this day, most of them continue to pursue legislation that allow for backdoors to monitor your calls, messages and general internet activity. Sadly, these invasive practices aren’t exclusive to the US, as governments across the world employ everything from ISP logging to phone malware if it allows them to spy on their citizens. While the documents Snowden released forced Congress to scale back the NSA's reach and offer some transparency, it is down to us to protect our basic human right to privacy in a world of overzealous surveillance. The National Security Agency ( NSA) has been collecting and storing data on anyone they can, regardless of whether they were US citizens. Back in 2013, Edward Snowden revealed that privacy was something the US government considers a privilege, not a right.
