Quantum Computing to Boost Security using Random Numbers

Quantum computers could produce genuinely random numbers according to new research. It could boost security, an ironic effect given fears over the ways cyber criminals could use quantum computing. In extremely simplified terms, a quantum computer ... uses quantum physics in which something can exist in more than one state at a time. That's in contrast to traditional computing where data is stored in bits that represent either a 0 or a 1 at any given time. To date, the main claimed advantage of quantum computing has been processing speed. The same "bit" representing multiple states removes a ... (view more)

Donut Theory Cracks Security Algorithm

A theory involving donuts has helped crack a proposed government security algorithm. It's nothing to do with distracting security guards, Better Call Saul-style, but rather advanced mathematics. Government agencies and others involved in security ... are constantly looking for new ways to encrypt data, with quantum computing seen as a potentially major threat. Most encryption methods used at the moment rely on length and complexity to deter brute force cracking techniques that simply try every possible decryption key. The idea is that it should take so many tries (on average) to get the right ... (view more)

New Google On-the-fly Encryption Ultra Fast, Secure

Google has developed a new type of encryption that could run on any Android device. It means added security even for the most basic phones, smart watches and smart TVs. The encryption in question isn't for transmitting data, but rather for data ... stored on a device. The data is controlled by unlock methods such as passwords, pin codes and fingerprints. The idea is that if somebody gets hold of a device and doesn't have the correct login credentials, they can't simply extract files from the device and access personal data. At the moment Android devices with encryption use Advanced Encryption ... (view more)

One of its core functions is a group system that lets a set of friends, family members, work colleagues or people with a share interest send a single message that reaches everyone in the group. The maximum group size is 256. One Message ... (view more)

Facebook to Offer Secure 'Secret Messaging'

Facebook is to let users send messages which cannot be read by anyone other than the recipient. It's also continuing to work on a feature that allows users to send temporary messages which self-destruct. The new feature is referred to as end-to-end ... encryption . That means it's set up in a way that, even if the message is intercepted, it can't be read by anyone other than the recipient. This is done by maintaining the encryption from the sending device to the receiving device, regardless of the route it takes across the Internet.
