Abstract
For port scanning an authentication bit sequence is created as an output of an authentication transformation, the authentication transformation having as input at least a given destination address and a given secret key. The authentication bit sequence is embedded in at least one authentication port scan event packet comprising the given destination address. At least one authentication port scan event packet is broadcast. Then, further port scan event packets are broadcast with given port identifiers and the given destination address. For port scanning detection, a received authentication bit sequence is derived from a least one authentication port scan event packet with identical source and destination addresses. Further port scan event packets are accepted with given port identifiers and the given destination address if authentication is given.
