No, they still use MTProto and not an AEAD construction.
- janinge 11y agoI was referring to the padding attack. Did they patch this? And are there any property of MTProto that makes it infeasible to replace AES IGE in a later revision of the protocol?
- CiPHPerCoder 11y agoThe problem isn't IGE. It's that they're using SHA1 (not HMAC-SHA1) in a "MAC and Encrypt" construction.
