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.  The update to the client Token processing requirements of
   RFC 7252 forbids non-secure reuse of Tokens to ensure binding of
   responses to requests when CoAP is used with security.
