Режим шифрования с возможностью аутентификации

Системы высокой доступности. 2013. Т. 9. № 3. С. 6-13.

We present a new authenticated encryption mode which can be used with arbitrary block cipher. The key property of this mode is that the length of authentication code can be twice as big as the block size of the cipher used. We provide estimates on the difficulty of constructing a collision and present performance results for implementation of our mode with the russian standard block cipher GOST 28147-89 and compare it with other well-known solutions.
