Abstract [en]

Public key cryptography is a very important means of obtaining confidentiality in computer security. There are only a few currently known mathematical functions that have the required properties to allow the implementation of public key cryptography. One of the most widespread public key

cryptographic systems, RSA, which is based upon the integer factoring problem, will be discussed. It is explained how a quantum computer, if ever constructed, is able to factorize integers into its prime constituents in polynomial time. In that case the RSA cryptosystem will not provide any confidentiality anymore. However, the elliptic curve cryptosystem, which is based upon a different mathematical problem for which currently no efficient algorithm exists, not even for a quantum computer, will, in that case, still be able to provide full computer security
