"Nearly Unbreakable" Encryption Scheme Inspired By Human Biology

rjmarvin (3001897) writes "Researchers at the U.K.'s Lancaster University have reimagined the fundamental logic behind encryption, stumbling across a radically new way to encrypt data while creating software models to simulate how the human heart and lungs coordinate rhythms. The encryption method published in the American Physical Society journal and filed as a patent entitled 'Encoding Data Using Dynamic System Coupling,' transmits and receive multiple encrypted signals simultaneously, creating an unlimited number of possibilities for the shared encryption key and making it virtually impossible to decrypt using traditional methods. One of the researchers, Peter McClintock, called the encryption scheme 'nearly unbreakable.'

      Heart and Lung rhythms are regulated using systems known as reaction-diffusion systems. An entire system is represented by a grid of cells, with every cell is at a particular state with a mix of chemicals, typicall named A,B,C ... There's the reaction part where A->2B, B->B+A, and then there's the diffusion part where the state of each cell is combined with it's neighbors. Each iteration calculates the new state of each cell, and applies the diffusion.

      Imagine if you stored your message as particular chemical levels, then ran a few thousand iterations - you would get a new unique state.

Encryption only works because the method of trying the one correct key is much less expensive than trying all possible keys.

      Biometrics are useful as identifiers, and to the degree that the biometric scan and matching process can be trusted, you can bootstrap an identification to an authentication. The kicker is that level of trust. If the biometric scanner is deployed in a secure area, to ensure it's not tampered, and the scanning process is monitored to ensure that the object being scanned actually is the person to be identified, and the template storage and matching process are also adequately secured, then biometric authentication is awesome.

      Alternatively, if the scanner isn't secured or monitored and the if security of the template store and matcher are also questionable, biometrics still aren't completely useless -- they just don't provide a significant level of assurance. If what you need is an extremely convenient way to unlock access with such low security needs that your other realistic alternative is to leave it unsecured, then biometrics are also fine. For example, if in the absence of a fingerprint reader you would leave your phone entirely unlocked, then unlocking it with a fingerprint is an improvement.

      In between, in contexts where security requirements aren't high enough to justify all of the effort and expense needed to make biometrics really strong, but where some security is actually needed, then biometrics are useless. That doesn't make them stupid, it just makes them the wrong tool for the job.

      According to Landauer's Principle the lowest possible amount of energy required to perform a single elementary computation is 2.85*10^-21 J. This means that even with a perfectly-efficient computer, to perform 2^256 elementary computations (assuming that an AES-256 trial decryption is a single elementary operation, which it isn't, but I'll ignore that) you would need 3.3*10^56 J. That's a lot.

      How much? Well, suppose we built a Dyson sphere and captured the entire energy output of the sun to power our perfectly-efficient computer. The annual output of the sun is 1.2*10^34 J, which means we'd need 2.75*10^22 years of solar energy to complete the search for one key. One problem with that: The sun won't last that long.

      Okay, so instead of just using a Dyson sphere to capture naturally-produced solar energy, suppose we found a way to convert the entire mass of the sun to energy. The theoretical mass energy of the sun is 1.8*10^47 J. That means you'd actually need the mass of just under two billion suns -- as well as an ideal computer and the ability to gather and convert all of those suns to energy in order to perform 2^256 operations.

      As Bruce Schneier put it in the intro to Applied Cryptography, brute force of a 256-bit keyspace is impossible until computers are made of something other than matter and and occupy something other than space.

      Of course, the 128-bit keyspace is miniscule compared to the 256-bit key space... but it's still unimaginably huge. Well beyond anyone's capabilities for at least several decades, perhaps longer. Suppose you had a trillion computers, each of which could test a trillion keys per second, allowing you to test 10^24 keys per second. It would still take you 10 million years to search a 128-bit key space.
