Pracovní skupina TLS vydala dva dokumenty

Jsou to:
  • TLS Out-of-Band Public Key Validation, draft 01,
    This document specifies a new TLS certificate type for exchanging raw public keys in Transport Layer Security (TLS) and Datagram Transport Layer Security (DTLS) for use with out-of-band authentication. Currently, TLS authentication can only occur via PKIX or OpenPGP certificates. By specifying a minimum resource for raw public key exchange, implementations can use alternative authentication methods. One such method is using DANE Resource Records secured by DNSSEC, Another use case is to provide authentication functionality when used with devices in a constrained environment that use whitelists and blacklists, as is the case with sensors and other embedded devices that are constrained by memory, computational, and communication limitations where the usage of PKIX is not feasible. The new certificate type specified can also be used to reduce the latency of a TLS client that is already in possession of a validated public key of the TLS server before it starts a (non-resumed) TLS handshake.
  • RFC 6347 on Datagram Transport Layer Security Version 1.2
    This document specifies version 1.2 of the Datagram Transport Layer Security (DTLS) protocol. The DTLS protocol provides communications privacy for datagram protocols. The protocol allows client/server applications to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery. The DTLS protocol is based on the Transport Layer Security (TLS) protocol and provides equivalent security guarantees. Datagram semantics of the underlying transport are preserved by the DTLS protocol. This document updates DTLS 1.0 to work with TLS version 1.2.
