Resume:
A mechanism for detecting denial of service attacks in a digital communications system is described. A probabilistically determined portion of input packets of a connection are processed using a hash function to determine whether the packets belong to the flow initiated by a TCP SYN packet. The hash function includes a secret key for additional security. The result of the hash function is added to a value which is dependent on the sequence number of a packet being processed.
