The Virtual Private Network (VPN) technology is a popular method that is used in the management of access within a private network. The performance of the VPN establishes the security and interoperability as a critical concern for the administration. The adoption of the classical VPN has many benefits, which includes the data transfer, the minimal delay, and a guaranteed non-bottleneck occurrence in the communication route establishing the shortest means of communication within the independent IP sec as an improvement of the performance.
Improving the VPN security performance is based on the password technique. The application of the quantum keys is a mechanism that has become quite popular as a means of protecting the network from eavesdroppers when the information is transferred within an insecure network.
The proposed solution is established in three procedures that include the user registration, used authentication, and the VPN tunnel, all which are critical stages, used in the management of various exposures and attacks. In the Use registration stage, there is the performance of key generation processes that call on the development of a password.
The password is based on the QKD technology that employs a key exchange method in the protection against eavesdroppers, which is an improvement of the pseudo-random numbers to reduce the probability of success in the brute force attacks.
The User authentication provides transparent authenticity for the legitimate users thus managing the access of the private resources.
In addition, the life cycle management of the password coupled with the harsh functions will solve the vulnerabilities within the network. The VPN tunnel is based on a one-time password mechanism that builds the highest security that ensures a particular key is employed once and further destroyed thus managing the level encryption.
