Abstract
This document defines two optional extensions to the Constrained Application Protocol (CoAP): the Repeat option and the Request-Tag option. Each of these options when integrity protected, such as with DTLS or OSCOAP, protects against certain attacks on CoAP message exchanges. The Repeat option enables a CoAP server to verify the freshness of a request by requiring the CoAP client to make another request and include a server-provided challenge. The Request-Tag option allows the CoAP server to match message fragments belonging to the same request message, fragmented using the CoAP Block-Wise Transfer mechanism. This document also specifies additional processing requirements on Block1 and Block2 options.
