It requires innodb_file_per_table to be set to ON, which is the default.
Actually, I'm not sure if that applies in all situations. It requires innodb_file_per_table to be on to be able to create or alter individual tables with encryption options, so in your case you will need it to be able to alter the tables and encrypt them, but need to investigate more about what happens with innodb_file_per_table set to off from the start.
