Re: [WG-UMA] AEMS in less than 300 words

Hi ilyah, You're right, there might be the potential threat vectors that could be exploited by bad actors. I've been working on a proof-of-concept project for the last few months and I do see room for improvement. For example, the use of an authorization code in the authorization email. This will be part of future work. Regards -Igor On Thu, Feb 25, 2021 at 6:03 PM Ilyah Simuni wrote:

Igor, Interesting idea for AEMS implementation. Wondering if you have done threat modeling on this architecture. I see a lot of potential attack vectors that might break the protocol. One concern is that the policy is separate from the email, so enforcement must be coded in the exchange protocol, which might not work as intended.

Regards, ilyah
