Hi all,

I completely agree with you! All i'm asking for is that what you are proposing is ratified in the spec clearly, without any ambiguities and that we don't implement what we *think* is correct, but implement the spec. If the spec specifies encryption, we should implement encryption, not authenticated encryption. One is not a direct substitute for the other and requires careful thinking. Similarly, the order of signing, encryption, decryption and authentication must be specified and explained clearly, specifically to avoid these kinds of discussions.

Just to keep everyone in the loop, we are currently having some internal discussions within Arm about TBBR/TBFU and all the questions/concerns that have been raised in this thread.

I will update you ASAP.

Best regards, Sandrine
