Improving VPN Security Performance Based on One-Time Password Technique Using Quantum Keys

Abstract

Network encryption technology has become an essential factor for organizational security. Virtual Private Network (VPN) or VPN encryption technology is the most popular technique used to prevent unauthorized users access to private network. This technique normally relies on mathematical function in order to generate periodic key. As a result, it may decrease security performance and vulnerable system, if high performance computing make rapid progress to reverse mathematicaln calculation to find out the next secret key pattern.The main contribution of this paper emphasizes on improving VPN performance by adopting quantum keys as a seed value into one-time password technique to encompasses the whole process of authentication, data confidentiality and security key management methodology in order to protect against eavesdroppers during data transmission over insecure network.
