What is a VPN Protocol?
Mobile devices have become an integral part of our daily lives. As we increasingly rely on them, we must ensure our data remains secure.
One of the best ways to achieve this is by using a Virtual Private Network (VPN) service, which encrypts our internet traffic and routes it through a secure server.
How do VPN Protocols work?
- VPN protocols govern how data is encrypted and transmitted through the internet.
- When you connect to a server, the protocol encrypts your data. It validates your identity before sending your data on its way.
- Once the data arrives at its destination, the protocol decrypts it so that it can be accessed.
- This process allows for faster, more secure communication between two systems.
On top of this strong security encryption, many VPN Protocols also provide user authentication mechanisms so that only authorized personnel can access their devices.
This added layer of security provides a strong line of defense for users’ data when accessing public networks.
With the ever-growing concern over cyber threats, it makes sense to take advantage of secure protocols like those used in VPNs to keep information safe while connected online.
What is IKEv2?
Not all VPN protocols are created equal; some are better suited for mobile devices than others.
One such protocol is the IKEv2 protocol, which plays a crucial role in mobile VPN connections.
What is IKEv2?
- IKEv2 is a protocol to establish a secure connection between a mobile device and a VPN server. It’s an updated version of IKEv1, developed in the 1990s and still used today.
- IKEv2 is much faster and more secure than its predecessor, making it an excellent choice for mobile VPN connections.
- It exchanges fewer messages in tunnel establishment and supports asymmetric and EAP authentication.
IKEv2 protocol uses encryption to protect the transmitted data and authentication from verifying the identities of both devices.
IKEv2 is also designed to be efficient and has mechanisms to quickly re-establish connections if they are disrupted.
This makes it ideal for mobile devices frequently moving between networks, such as those working from home.
How Does IKEv2 Work?
It’s fascinating how IKEv2 works; It’s like its own little world, with a complex set of rules and regulations to ensure secure connections.
IKEv2 operates by creating two distributed secure tunnels between two endpoints.
Without going into too much of a technical deep-dive, IKEv2 employs a combination of industry-standard algorithms to provide secure network connections.
These algorithms include:
- AES (Advanced Encryption Standard) is an encryption cipher used to ensure that all data transmitted over the connection is secure
- HMAC (Hashed Message Authentication Code) is used to verify the integrity of the data.
IKEv2 also uses a variety of exchange protocols to establish the connection.
These protocols include:
- ISAKMP (Internet Security Association and Key Management Protocol) deals with negotiating security parameters behind the scenes
- The Diffie-Hellman key exchange generates a shared secret key between you and your VPN server – so no one else can access it!
Due to its fast reconnection time, modular design, and ability to function across multiple platforms, many larger organizations have adopted this as their go-to protocol for secure communication.
As you can see, IKEv2 steps up its security game to keep your traffic safe while on the go!
