pycrate_osmo: add RRCTL protocol definition #175

Closed axilirator closed 2 years ago

axilirator commented 2 years ago

RRCTL is a non-standard, ad-hoc protocol (inspired by Osmocom's L1CTL) that allows an external NAS entity to control the RRC layer of srsUE [1][2]. This protocol enables security researchers to test LTE networks against various exceptional scenarios. Similar work [3] has been done by researchers from Korea Advanced Institute of Science and Technology (KAIST), but unfortunately the source code had never been published.

Excellent, thanks for this fantastic PR :) I am pretty sure @p1-laurent will be happy, too. Few years ago, we checked how to manage srs-ue in "uncommon" ways, but this is much more complete than everything we could have done.

Excellent idea, from its early start in 2019.
