* ITU Recommendation on H.323 Protocol for Packet Based Multimedia Systems.
* The NIST documentations on FIPS and the various Crypto algorithms.
The first two are an "umbrella" of protocols and thus the specifications go from overview to extremely detailed in a very nice step-by-step manner. The third one shows you how to specify detailed and complicated algorithms.
Writing good Specifications is extremely demanding! But this is the only way to really understand the Domain.
