key encryption

Breaking encryption using quantum computing could be 20 times easier than previously thought. It's not happening any time soon, but the point where computer security needs an overhaul may be earlier than expected. Most computer encryption today is ... based on creating an encryption key by multiplying two large prime numbers together. The beauty and simplicity is that doing this is very simple, but reversing the process to work out what the two numbers originally were is incredibly complex. While a computer can eventually figure it out, the idea is that it would take so long (potentially years or ... (view more)
