Issue 30/06/2004
|
||||
|
||||
This file contains the code for declaring the tables needed to implement
|
||||
AES. The file aesopt.h is assumed to be included before this header file.
|
||||
If there are no global variables, the definitions here can be used to put
|
||||
the AES tables in a structure so that a pointer can then be added to the
|
||||
AES context to pass them to the AES routines that need them. If this
|
||||
facility is used, the calling program has to ensure that this pointer is
|
||||
managed appropriately. In particular, the value of the t_dec(in,it) item
|
||||
in the table structure must be set to zero in order to ensure that the
|
||||
tables are initialised. In practice the three code sequences in aeskey.c
|
||||
that control the calls to gen_tabs() and the gen_tabs() routine itself will
|
||||
have to be changed for a specific implementation. If global variables are
|
||||
available it will generally be preferable to use them with the precomputed
|
||||
FIXED_TABLES option that uses static global tables.
|
||||
|
||||
The following defines can be used to control the way the tables
|
||||
are defined, initialised and used in embedded environments that
|
||||
require special features for these purposes
|
||||
|
||||
the 't_dec' construction is used to declare fixed table arrays
|
||||
the 't_set' construction is used to set fixed table values
|
||||
the 't_use' construction is used to access fixed table values
|
||||
|
||||
256 byte tables:
|
||||
|
||||
t_xxx(s,box) => forward S box
|
||||
t_xxx(i,box) => inverse S box
|
||||
|
||||
256 32-bit word OR 4 x 256 32-bit word tables:
|
||||
|
||||
t_xxx(f,n) => forward normal round
|
||||
t_xxx(f,l) => forward last round
|
||||
t_xxx(i,n) => inverse normal round
|
||||
t_xxx(i,l) => inverse last round
|
||||
t_xxx(l,s) => key schedule table
|
||||
t_xxx(i,m) => key schedule table
|
||||
|
||||
Other variables and tables:
|
||||
|
||||
t_xxx(r,c) => the rcon table
