Signature specification for encrypted packet streams

摘要

Methods, systems, and products are disclosed for specifying a signature for an encrypted packet stream. One method receives the encrypted stream of packets, and encryption obscures the contents of a packet. A signature for insertion into the stream of packets is specified, and the signature identifies a type of data encrypted within the stream of packets. The signature identifies the contents of the packet despite the encryption obscuring the contents.

主权项

1. A method, comprising:
receiving an encrypted stream of packets, wherein data included in the encrypted stream of packets is obscured by encryption; specifying a signature for the encrypted stream of packets; identifying an application type of the data included in the encrypted stream of packets using the signature, wherein the receiving, specifying and identifying are performed on at least one processor; and communicating the signature to a communications device; wherein the signature is based on one of size of the packets and timing between the packets; wherein specifying the signature comprises specifying a packet for time-based insertion into the encrypted stream of packets, the packet having a size that identifies the application type of the data and not comprising data of the application type; and wherein specifying the signature comprises establishing a pattern of packet sizes.
