17. Security Considerations

The compression protocols in this document run on top of a link-layer protocol. The compression protocols themselves introduce no new additional vulnerabilities beyond those associated with the specific link-layer technology being used.

Denial-of-service attacks are possible if an intruder can introduce (for example) bogus Full Header packets onto the link. However, an intruder having the ability to inject arbitrary packets at the link- layer in this manner raises additional security issues that dwarf those related to the use of header compression.

We advise implementors against identifying packet streams with the aid of information that is encrypted, even if such information happens to be available to the compressor. Doing so may expose traffic patterns.
