All, One IESG review comment on OSCORE related to the use of random Sender IDs. As a remnant from previous versions the draft speaks about "uniformly random distributed byte strings if the probability of collisions is negligible”. With the default AEAD algorithm the current available size of Sender ID is 7 bytes. Question: Is anyone interested in deployments which must have large random Sender IDs, or can we assume that unique Sender IDs are available or assigned/agreed, e.g. at the same time when the Master Secret is? Unless someone objects we will remove the formulation about random Sender IDs. Regards Göran
