Imagine being able to break any classical encryption algorithm in a matter of seconds. Some would say that this statement is impossible, and it is in a classical sense. But with the advent of quantum computational theory, new methods of computation and algorithms are being developed that are making this statement more realistic. Quantum computation threatens classical encryption algorithms as i...

Ensuring that p and q are very large prime numbers ensures the security of the system. Although multiplying large prime numbers is equivalent to multiplying any two large numbers, a trivial operation on a computer, its inverse is practically impossible. This operation is thus called a one-way function. This ensures that although one is given n, the product of the two prime numbers, discovering ...

A DOS attack consists of rendering a network unable to carry legitimate user data. This can be done via attacking routers directly or by flooding the network with excessive traffic. Router attacks restrict the router’s ability to forward as many packets or its ability to forward them properly. This can be achieved by abusing known vulnerabilities to modify routing tables (using protocols such a...
