Abstract:
   This document specifies enhancements to the Constrained Application
   Protocol (CoAP) that mitigate security issues in particular use
   cases.  The Echo option enables a CoAP server to verify the freshness
   of a request or to force a client to demonstrate reachability at its
   claimed network address.  The Request-Tag option allows the CoAP
   server to match block-wise message fragments belonging to the same
   request.  This document updates RFC7252 with respect to the client
   Token processing requirements, forbidding non-secure reuse of Tokens
   to ensure binding of response to request when CoAP is used with
   security, and with respect to amplification mitigation, where the use
   of Echo is now recommended.
