What technologies are used in UVMs VPN system?
UVM’s VPN service is based on the open IPsec standard. This is really an “umbrella” standard that dictates everything from exchanging secure keys, to packet formats and types, to the methods of encryption that are used. Other standards such as Diffie-Hillman key exchange, Authenticated Header, Encapsulating Security Payload, Data Encryption Standard/Cypher Block Chaining (DES/CBC), and Internet Key Exchange (IKE) are used as part of the IPsec standard. IPsec is primarily defined in RFC2401.
