The main aim of any VPN is to create a safe encrypted tunnel for internet traffic, protecting it from hackers and other third parties. VPN providers can choose from a variety of protocols - OpenVPN, IKEv2, L2TP, etc., to create and manage an encrypted tunnel. But every protocol has its own advantages and disadvantages.
Although OpenVPN is the most popular option, it was developed over 20 years ago and internet technologies have made some progress since 2001. WireGuard is a game-changer in the world of VPN protocols and has already got some credit in the cybersecurity industry.
WireGuard is a new open-source VPN protocol that uses state-of-the-art cryptography and aims to outperform the existing VPN protocols like IPsec and OpenVPN. It was originally released for the Linux kernel, but is now cross-platform and can be widely deployable. Though WireGuard is still under development, it can already be considered as one of the most secure, fast, and easy-to-use solutions in the VPN industry.
The WireGuard protocol features a much lighter code base than most VPN protocols (at least open-source ones). It consists of just around 4000 lines of code, which largely contrasts strongSwan/IPsec and OpenVPN/OpenSSL, which have 400,000 and 600,000 lines of code correspondingly.
Such a light build means WireGuard is much easier to audit for security vulnerabilities. Audit of WireGuard may be done by a single individual, whereas auditing of enormous IPSec or OpenVPN’s codebases is a difficult task even for a whole team of security experts. WireGuard’s smaller codebase also implies a minimal attack surface that can be exploited by cybercriminals.
The state-of-the-art cryptography employed by WireGuard includes the following protocols and cryptographic primitives:
The usage of high-speed cryptographic primitives and the fact that WireGuard lives inside the Linux kernel can make networking both secure and very high-speed. WireGuard’s good performance makes it suitable for both small devices like smartphones and loaded backbone routers.
Another noteworthy peculiarity about WireGuard VPN protocol is that connection handshakes take place every few minutes to provide rotating keys for perfect forward secrecy. They are performed based on time rather than the contents of data packets.
There is an in-built mechanism ensuring that the latest keys and handshakes are up-to-date and renegotiated when required. It utilizes a separate packet queue per host, thus minimizing packet loss during handshakes, at the same time providing uninterrupted performance for clients.
Simply put, you turn on your device and everything is handled automatically for you. No need to disconnect, reconnect, or reinitialize, just enjoy the smooth VPN connection!
