Abstract:
With emergence of Internet of Things(IoT), DTLS is being widely
considered as a protocol of choice for communication security in IoT
applications. Further, AES_CCM has emerged as the cipher of choice in
constrained environments. Constrained Application Protocol (CoAP),
which is the application layer protocol for resource constrained
environments, mandates DTLS as underlying security protocol and
proposes AES_CCM based ciphers to be used with different key exchange
methods. AEAD ciphers requires an explicit nonce of 8 bytes must be
carried in each transmitted record.This document defines a TLS (and
DTLS) extension, which will allow clients and servers to omit the
explicit nonce sent in TLS/DTLS records. This document can be
considered as an extended version of "Transport Layer Security (TLS)
Extensions : Extension Definitions". The extension defined in this
document apply equally to both DTLS and TLS protocols.
