Abstract
A method for authenticating packet communication traffic includes receiving a data packet sent over a network from a source address to a destination address and reading from the packet a value of a field that is indicative of a number of hops traversed by the packet since having been sent from the source address. The authenticity of the source address is assessed responsive to the value.
