One argument that the pro-encryption camp is using is that it provides Integrity to TV. Encryption provides an important quality, such that it prevents someone from interfering with a broadcast and broadcasting their own, psuedo authoritative, pirate signal.
This can also be achieved with signing. These arguments are spurious. Please comment to oppose encryption.
- phh 3y agoYou can't reasonably sign broadcast. Encryption is done at 188B packets to be robust to packet loss. That being said that argument is still BS because the attacker can just send a non encrypted signal.
- SV_BubbleTime 3y agoWhy couldn’t a 188B packet stream be signed? If it can be encrypted, it can be signed easier.
- drmpeg 3y ago188 byte Transport Streams are allowed in ATSC 3.0. but it's a legacy mode. All ATSC 3.0 stations on the air use UDP over IP packets.
- whimsicalism 3y agoMy intuition is that if it can be encrypted, it can definitely be signed. Is that wrong?

- LocalH 3y agoWhen was the last signal intrusion? LMAO
- drewg123 3y ago35 years ago: https://en.wikipedia.org/wiki/Max_Headroom_signal_hijacking https://en.wikipedia.org/wiki/Max_Headroom_signal_hijacking So yeah, it is not much of a pressing issue.
- ronsor 3y agoHasn't happened since digital TV. It's more likely that a broadcasting station is hacked and the stream is hijacked there rather than hijacked using a rogue transmitter.
- darkarmani 3y agoFine. Let's agree to that -- encrypt everything and publish all of the decryption keys. Make a huge fine to encrypt anything with a non-published decryption key.
- thfuran 3y agoWhat does that accomplish?
- nofunsir 3y agoIt reveals how silly the argument of parent commenter is.
- sircastor 3y agoThat sounds like something you could lawyer out of or wait until the enforcement authority focuses on something else. Encryption here only benefits the content owner and comes at the cost of the user. There's no value here in adding encryption.
- tech234a 3y agoThe ATSC 3.0 Security Authority [1] already describes signing and encryption as separate features.
