![]() ![]() Symmetric keys are most commonly used in IPSec VPNs because of its good performance. ![]() * Because both sides use the same key, key management becomes a huge issue. AES does not require ASIC because it is a faster protocol * Juniper has ASIC that provides DES & 3DES. * 40bits to 1024bit keys (fast, widely used for bulk data encryption) ![]() Same key is used for encryption and decryption What are the available solutions for these 3 challenges ? We want to keep the date secure & hidden (confidentiality), we need to ensure that data has not been changed (integrity) and we’d like to make sure that the data really comes from the advertised source (authentication). If we want to tunnel traffic over a public network, we are faced with some issues. The mail tunneling protocols are L2TP, GRE and IPSec. The need for VPNĪ VPN can be defined as the simulation of a private connection by tunneling traffic between 2 private locations. Today, it is time to take it one step further and to look at setting up and especially troubleshooting IPSec VPN’s with Juniper Netscreen devices. A few days ago, I have posted some ScreenOS basics on this blog. ![]()
