The Liaison statement can be found here: https://datatracker.ietf.org/liaison/1258/ The Internet Society will forward this liaison statement to ISO/IEC JTC1/SC6 on their letterhead. This will carry more weight than a statement just from the IESG and IAB because the Internet Society holds a Class A liaison with SC6 on behalf of the IETF. This liaison is provided to ISO/IEC JTC1/SC6 because they are entertaining adopting the TISec. The IESG and the IAB believe TISec provides the same services as IPsec. The IESG rejected a request for a protocol number assignment for TISec in August of last year for that reason, but the IESG offered an experimental code point while TISec was under review in ISO. A liaison was sent to ISO informing them of this decision in December (see ). The TISec proponents have indicated that they believe that TISec is different than IPsec. This liaison is a response this statement. It points out how IPsec supports the same functionality, and it encourages the TISec proponents to engage in the IETF process to specify the use of their national algorithms in IPsec, as has been done for other national algorithms.
