The Constrained Application Protocol (CoAP) is a standard communication protocol for resource-constrained devices in the Internet of Things (IoT). Many IoT deployments require proxies to support asynchronous communication between edge devices and the back-end. This allows (non-trusted) proxies to access sensitive parts of CoAP messages. Object Security for Constrained RESTful Environments (OSCORE) is a recent standard protocol that provides end-to-end security for CoAP messages at the application layer. Unlike the commonly used standard Datagram Transport Layer Security (DTLS), OSCORE efficiently provides selective integrity protection and encryption on different parts of CoAP messages. Thus, OSCORE enables end-to-end security through intermediary (non-trusted) proxies, while still allowing them to perform their expected services, with considerable security and privacy improvements.
