Description of Working Group:

The TLS Working Group was established in 1996 to standardize a
'transport layer' security protocol. The working group began with SSL
version 3.0. The TLS Working Group has completed a series of
specifications that describe the Transport Layer Security protocol
versions 1.0 and 1.1, extensions to the protocol, and new
ciphersuites to be used with TLS.

The primary goal of the WG is to publish a revision of TLS, version 
1.2, that removes the protocol's dependency on the MD5 and SHA-1 digest
algorithms, which have been either wholly or partially compromised by
recent research. The TLS WG will also work on new authenticated
encryption modes for TLS, including modes based on counter mode
encryption (CTR) and combined encryption/authentication modes, and
may define major new cipher suites for TLS for this purpose. In the
preparation of TLS 1.2, the WG will attempt to avoid gratuitous
changes to TLS 1.1.

 Goals and Milestones:

   Done         Agreement on charter and issues in current draft. 

   Done         Final draft for Secure Transport Layer Protocol ('STLP') 

   Done         Working group 'Last Call' 

   Done         Submit to IESG for consideration as a Proposed Standard. 

   Done         First revised draft of TLS specification 

   Done         TSL 1.1 Specification 

   Done         First draft of TLS 1.2 specification, including CTR mode cipher 
                suites 

   Done         First draft of specification for cipher suites with combined 
                encryption/authentication modes 

   Dec 2006       Submit specification of TLS 1.2 specification to IESG for 
                publication as Proposed Standard 

   Dec 2006       Submit specification of cipher suites with combined 
                encryption/authentication modes to IESG for publication, with 
                at least one of these suites to be Proposed Standard
