The first fifteen bytes of the 09 F9 key are contained in the RGB encoding of the five colors, with each color providing three bytes of the key.
A round can then be performed with 16 table lookup operations and 12 32-bit exclusive-or operations, followed by four 32-bit exclusive-or operations in the AddRoundKey step. [12] Alternatively, the table lookup operation can be performed with a single 256-entry 32-bit table (occupying 1024 bytes) followed by circular rotation operations.
