The danger of TLS Zero RTT
Why early data is subject to Replay attacks —  TLS 1.3 had the clever idea to separate the single negotiation of a cipher suite into three negotiations for key exchange, symmetric cipher and digital signature. This allowed the TLS 1.3 to shave an entire round trip reducing it to 1-RTT (round trip time). The client proposes its own key…
