If we have some random data (with length a multiple of block size to avoid padding) and encrypt it with a block cipher with a weak key (maybe it's derived from a four digit number for example), would it be possible to break the encryption? If there is no MAC and we are not using authenticated enc...
Does anyone know any applications that prefer using Kuznyechik? I just found out about this in a bunch of IP Core targets from a fab. It only uses 10 rounds, is physically smaller than AES128. I'm just curious why it could have been included and someone spent a lot of time optimizing the layout.
