uint8_t	TK1 [16]
uint32_t	k [160]

Detailed Description

Structure of an expanded SKINNY-128-384+ key schedule.

The TK1 field can be modified freely by the application between calls to the encryption and decryption functions. The rest of the structure should be treated as opaque.

Note

This structure is sized to hold the largest possible key schedule in the back end implementation. The actual schedule may be smaller than this if a memory-constrained back end is in use. The function skinny_128_384_plus_get_key_schedule_size() can be used to dynamically allocate a memory buffer of the correct size.
