Under such assumption, even dynamic reauth in HTTP/1.1 is unsafe. If one additionally assumes causality, dynamic reauth in non-pipelined HTTP/1.1 may be safe, but dynamic reauth in HTTP/2 (or HTTP/1.1 with pipelining) is still unsafe. -Ilari _______________________________________________ TLS mailing list TLS@ietf.org https://www.ietf.org/mailman/listinfo/tls
