[Cryptography] FW: RFC 7253 on The OCB Authenticated-Encryption Algorithm

[Stephen Farrell]

<iprcrapology>

This RFC is an IRTF stream RFC. The IRTF follows the IETF's IPR
policies, which are set out in various RFCs/BCPs listed at [1].
The basic idea though is that if you personally know of e.g. a
patent (filing), then you need to declare and then the relevant
IETF WG or whatever can decide what to do. While there is a
preference for things that are not known to be encumbered, in this
world you can't be sure about that. If interested, or you want
to comment on this, there's a list [2] which is discussing
clarifications/twesks to these policies. And if you are doing
stuff in the IETF/IRTF you need to go read the actual RFCs/BCPs
yourself, i.e. the above is not the policy but a pointer to the
policy (yes, a lawyer said that to me once;-)
