I’m working on a college paper about TLS and I am asked why TLS sequence number counter is a 64-bit number when TLS only uses 32-bit sequence number in its messages. I’ve looked around for a while, even checked the RFC and I have found nothing so far. Can anyone help me?
Looks to me like the question is just plain wrong. TLS uses 64-bit sequence numbers, and these are implicit (i.e. not transmitted as part of TLS messages).
Maybe the original questions is confusing SQNs in TLS with SQNs in IPsec: there, 32-bit sequence numbers are included in ESP and AH header fields, but 64-bit extended sequence numbers (ESNs) are permitted by the relevant RFCs.
