IKE
This signature detects Internet Security Association and Key Management Protocol (ISAKMP) Internet Key Exchange (IKE), which is defined in RFC 2409 and uses a Diffie-Hellman key exchange to set up a shared session secret, from which cryptographic keys are derived. Public key techniques or, alternatively, a Pre-shared key (aka preshared secret), is used to mutually authenticate the communicating parties. IKE usually operates on UDP port 500.
