IPsec protects and authenticates IP packets between source and destination. IPsec can protect traffic from Layer 4 through Layer 7. Using the IPsec framework, IPsec provides confidentiality, integrity, origin authentication, and Diffie-Hellman. Choosing the IPsec protocol encapsulation is the first building block of the framework. IPsec encapsulates packets using AH or ESP. The degree of confidentiality depends on the encryption algorithm and the length of the key used in the encryption algorithm. The HMAC is an algorithm that guarantees the integrity of the message using a hash value. The device on the other end of the VPN tunnel must be authenticated before the communication path is considered secure. A PSK value is entered into each peer manually. The PSK is combined with other information to form the authentication key. RSA authentication uses digital certificates to authenticate the peers. The local device derives a hash and encrypts it with its private key. The encrypted hash is attached to the message and is forwarded to the remote end and acts like a signature. DH provides a way for two peers to establish a shared secret key that only they know, even though they are communicating over an insecure channel.
