Isn't the whole point that they're trying to make mathematics illegal? To my knowledge, encryption is currently legal.
To those who say "it's impossible to make encryption illegal": there have been sillier laws. George Orwell once imagined a society where 2+2=5 was a law. While they usually do, laws don't have to make sense.
We don't need to look to fiction in the US to see examples of encryption controlled by the State with laws, it was literally US government policy in the 90s/early 2000s. Examples include banning export of encryption keys longer than 40 bits etc to make it easier for US secret services to crack the foreign purchaser's systems, the debate during the Clinton administration on what should be permitted encryption-wise was intense at times.
My favourite example in the world of "silly" laws - Saudi Arabia invests massive money in scientific research, and still executes people for Sorcery and Witchcraft
