In section 6, protocol functions should be explained more to
make the reader understand the CROUS. Besides, some functions using hash
functions or PRF should be explained. For generating t_e, is the same
hash function for cid used?
Protocol functions in Sec.6 are not easy to read. Authors should make
them more readable with a deep explanation.
What do they mean by readable? Do they want all technical details there and not indirected (refs to building blocks). Or do they want more why in the description?
