AnnaBridge	156:ff21514d8981	56	* @details
AnnaBridge	156:ff21514d8981	57	* In order for cryptographic support, users are recommended to consider the
AnnaBridge	156:ff21514d8981	58	* crypto APIs of the mbedTLS library provided by Silicon Labs instead of the
AnnaBridge	156:ff21514d8981	59	* interface provided in em_crypto.h. The mbedTLS library provides a much
AnnaBridge	156:ff21514d8981	60	* richer crypto API, including hardware acceleration of several functions.
AnnaBridge	156:ff21514d8981	61	*
AnnaBridge	156:ff21514d8981	62	* The main purpose of em_crypto.h is to implement a thin software interface
AnnaBridge	156:ff21514d8981	63	* for the CRYPTO hardware functions especially for the accelerated APIs of
AnnaBridge	156:ff21514d8981	64	* the mbedTLS library. Additionally em_crypto.h implement the AES API of the
AnnaBridge	156:ff21514d8981	65	* em_aes.h (supported by classic EFM32) for backwards compatibility. The
AnnaBridge	156:ff21514d8981	66	* following list summarizes the em_crypto.h inteface:
AnnaBridge	156:ff21514d8981	67	* @li AES (Advanced Encryption Standard) @ref crypto_aes
AnnaBridge	156:ff21514d8981	68	* @li SHA (Secure Hash Algorithm) @ref crypto_sha
AnnaBridge	156:ff21514d8981	69	* @li Big Integer multiplier @ref crypto_mul
AnnaBridge	156:ff21514d8981	70	* @li Functions for loading data and executing instruction sequences @ref crypto_exec
AnnaBridge	156:ff21514d8981	71	*
AnnaBridge	156:ff21514d8981	72	* @n @section crypto_aes AES
AnnaBridge	156:ff21514d8981	73	* The AES APIs include support for AES-128 and AES-256 with block cipher
AnnaBridge	156:ff21514d8981	74	* modes:
AnnaBridge	156:ff21514d8981	75	* @li CBC - Cipher Block Chaining mode
AnnaBridge	156:ff21514d8981	76	* @li CFB - Cipher Feedback mode
AnnaBridge	156:ff21514d8981	77	* @li CTR - Counter mode
AnnaBridge	156:ff21514d8981	78	* @li ECB - Electronic Code Book mode
AnnaBridge	156:ff21514d8981	79	* @li OFB - Output Feedback mode
AnnaBridge	156:ff21514d8981	80	*
AnnaBridge	156:ff21514d8981	81	* For the AES APIs Input/output data (plaintext, ciphertext, key etc) are
AnnaBridge	156:ff21514d8981	82	* treated as byte arrays, starting with most significant byte. Ie, 32 bytes
AnnaBridge	156:ff21514d8981	83	* of plaintext (B0...B31) is located in memory in the same order, with B0 at
AnnaBridge	156:ff21514d8981	84	* the lower address and B31 at the higher address.
AnnaBridge	156:ff21514d8981	85	*
AnnaBridge	156:ff21514d8981	86	* Byte arrays must always be a multiple of AES block size, ie. a multiple
AnnaBridge	156:ff21514d8981	87	* of 16. Padding, if required, is done at the end of the byte array.
AnnaBridge	156:ff21514d8981	88	*
AnnaBridge	156:ff21514d8981	89	* Byte arrays should be word (32 bit) aligned for performance
AnnaBridge	156:ff21514d8981	90	* considerations, since the array is accessed with 32 bit access type.
AnnaBridge	156:ff21514d8981	91	* The core MCUs supports unaligned accesses, but with a performance penalty.
AnnaBridge	156:ff21514d8981	92	*
AnnaBridge	156:ff21514d8981	93	* It is possible to specify the same output buffer as input buffer as long
AnnaBridge	156:ff21514d8981	94	* as they point to the same address. In that case the provided input buffer
AnnaBridge	156:ff21514d8981	95	* is replaced with the encrypted/decrypted output. Notice that the buffers
AnnaBridge	156:ff21514d8981	96	* must be exactly overlapping. If partly overlapping, the behavior is
AnnaBridge	156:ff21514d8981	97	* undefined.
AnnaBridge	156:ff21514d8981	98	*
AnnaBridge	156:ff21514d8981	99	* It is up to the user to use a cipher mode according to its requirements
AnnaBridge	156:ff21514d8981	100	* in order to not break security. Please refer to specific cipher mode
AnnaBridge	156:ff21514d8981	101	* theory for details.

AnnaBridge	156:ff21514d8981	126	* @n @section crypto_mul CRYPTO_Mul
AnnaBridge	156:ff21514d8981	127	* @ref CRYPTO_Mul is a function for multiplying big integers that are
AnnaBridge	156:ff21514d8981	128	* bigger than the operand size of the MUL instruction which is 128 bits.
AnnaBridge	156:ff21514d8981	129	* CRYPTO_Mul multiplies all partial operands of the input operands using
AnnaBridge	156:ff21514d8981	130	* MUL to form a resulting number which may be twice the size of
AnnaBridge	156:ff21514d8981	131	* the operands.
AnnaBridge	156:ff21514d8981	132	*
AnnaBridge	156:ff21514d8981	133	* CRPYTO_Mul is typically used by RSA implementations which perform a
AnnaBridge	156:ff21514d8981	134	* huge amount of multiplication and square operations in order to
AnnaBridge	156:ff21514d8981	135	* implement modular exponentiation.
AnnaBridge	156:ff21514d8981	136	* Some RSA implementations use a number representation including arrays
AnnaBridge	156:ff21514d8981	137	* of 32bit words of variable size. The user should compile with
AnnaBridge	156:ff21514d8981	138	* -D USE_VARIABLE_SIZED_DATA_LOADS in order to load these numbers
AnnaBridge	156:ff21514d8981	139	* directly into CRYPTO without converting the number representation.
AnnaBridge	156:ff21514d8981	140	*
AnnaBridge	156:ff21514d8981	141	* @n @section crypto_exec Load and Execute Instruction Sequences
AnnaBridge	156:ff21514d8981	142	* The functions for loading data and executing instruction sequences can
AnnaBridge	156:ff21514d8981	143	* be used to implement complex algorithms like elliptic curve cryptography
AnnaBridge	156:ff21514d8981	144	* (ECC)) and authenticated encryption algorithms. There are two typical
AnnaBridge	156:ff21514d8981	145	* modes of operation:
AnnaBridge	156:ff21514d8981	146	* @li Multi sequence operation
AnnaBridge	156:ff21514d8981	147	* @li Single static instruction sequence operation
AnnaBridge	156:ff21514d8981	148	*
AnnaBridge	156:ff21514d8981	149	* In multi sequence mode the software starts by loading input data, then
AnnaBridge	156:ff21514d8981	150	* an instruction sequence, execute, and finally read the result. This
AnnaBridge	156:ff21514d8981	151	* process is repeated until the full crypto operation is complete.
AnnaBridge	156:ff21514d8981	152	*
AnnaBridge	156:ff21514d8981	153	* When using a single static instruction sequence, there is just one
AnnaBridge	156:ff21514d8981	154	* instruction sequence which is loaded initially. The sequence can be setup
AnnaBridge	156:ff21514d8981	155	* to run multiple times. The data can be loaded during the execution of the
AnnaBridge	156:ff21514d8981	156	* sequence by using DMA, BUFC and/or programmed I/O directly from the MCU
AnnaBridge	156:ff21514d8981	157	* core. For details on how to program the instruction sequences please refer
AnnaBridge	156:ff21514d8981	158	* to the reference manual of the particular Silicon Labs device.
AnnaBridge	156:ff21514d8981	159	*
AnnaBridge	156:ff21514d8981	160	* In order to load input data to the CRYPTO module use any of the following
AnnaBridge	156:ff21514d8981	161	* functions:
