Re: [6tisch] I-D Action: draft-ietf-6tisch-minimal-security-12.txt

Dear all,

This is a version of the minimal-security draft that incorporates the resolutions to the two issues discussed during the Montreal meeting: ASN replay attack and the usage of different authentication tag lengths with the same CCM key.
