摘要: The current standard to exchange a secret key for ensuring secure data transmission within the SSL/TLS protocol is based on Public-Key encryption. This method only as long computation power of potential attacker limited. So far, way make an unconditional exchange, use quantum distribution (QKD). With latest figures sifting rates provided by NIST, we show which authentic theoretical final are possible. Furthermore present modified protocol, uses distribution, in different encryption variants.
