Comment Intercepting encrypted communications! OMG! (Score 3, Insightful) 89
Uh.. the whole point of transport layer encryption is that you assume an attacker can record your communication and the encryption prevents the attacker from figuring out the real contents of the communication.
If you know for a fact that no unauthorized party can actually tap to your communication channel.. you don't even have to bother with the encryption in the first place.
The rest of the issue is due to the fact that the SS7 protocol is a byzantinely complex and very very old standard going way WAY back before data security was taken into account.
For all the people saying this is some intentional backdoor... if the NSA really were that smart to sneak this into a design-by-committee standard where hundreds of engineers spent years niggling over details, then you might as well give up now because you just said they are smart enough to insert backdoors into the Linux kernel or any other complex open source project too and they'll get away with it for decades before they get caught.
