- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- The CRYP HAL driver can be used in CRYP or TinyAES IP as follows:
- (#)Initialize the CRYP low level resources by implementing the HAL_CRYP_MspInit():
- (##) Enable the CRYP interface clock using __HAL_RCC_CRYP_CLK_ENABLE()or __HAL_RCC_AES_CLK_ENABLE for TinyAES IP
- (##) In case of using interrupts (e.g. HAL_CRYP_Encrypt_IT())
- (+++) Configure the CRYP interrupt priority using HAL_NVIC_SetPriority()
- (+++) Enable the CRYP IRQ handler using HAL_NVIC_EnableIRQ()
- (+++) In CRYP IRQ handler, call HAL_CRYP_IRQHandler()
- (##) In case of using DMA to control data transfer (e.g. HAL_CRYP_Encrypt_DMA())
- (+++) Enable the DMAx interface clock using __RCC_DMAx_CLK_ENABLE()
- (+++) Configure and enable two DMA streams one for managing data transfer from
- memory to peripheral (input stream) and another stream for managing data
- transfer from peripheral to memory (output stream)
- (+++) Associate the initialized DMA handle to the CRYP DMA handle
- using __HAL_LINKDMA()
- (+++) Configure the priority and enable the NVIC for the transfer complete
- interrupt on the two DMA Streams. The output stream should have higher
- priority than the input stream HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ()
- (#)Initialize the CRYP according to the specified parameters :
- (##) The data type: 1-bit, 8-bit, 16-bit or 32-bit.
- (##) The key size: 128, 192 or 256.
- (##) The AlgoMode DES/ TDES Algorithm ECB/CBC or AES Algorithm ECB/CBC/CTR/GCM or CCM.
- (##) The initialization vector (counter). It is not used in ECB mode.
- (##) The key buffer used for encryption/decryption.
- (##) The Header used only in AES GCM and CCM Algorithm for authentication.
- (##) The HeaderSize The size of header buffer in word.
- (##) The B0 block is the first authentication block used only in AES CCM mode.
- (#)Three processing (encryption/decryption) functions are available:
- (##) Polling mode: encryption and decryption APIs are blocking functions
- i.e. they process the data and wait till the processing is finished,
- e.g. HAL_CRYP_Encrypt & HAL_CRYP_Decrypt
- (##) Interrupt mode: encryption and decryption APIs are not blocking functions
- i.e. they process the data under interrupt,
- e.g. HAL_CRYP_Encrypt_IT & HAL_CRYP_Decrypt_IT
- (##) DMA mode: encryption and decryption APIs are not blocking functions
- i.e. the data transfer is ensured by DMA,
- e.g. HAL_CRYP_Encrypt_DMA & HAL_CRYP_Decrypt_DMA
- (#)When the processing function is called at first time after HAL_CRYP_Init()
- the CRYP peripheral is configured and processes the buffer in input.
- At second call, no need to Initialize the CRYP, user have to get current configuration via
- HAL_CRYP_GetConfig() API, then only HAL_CRYP_SetConfig() is requested to set
- new parametres, finally user can start encryption/decryption.
- (#)Call HAL_CRYP_DeInit() to deinitialize the CRYP peripheral.
- [..]
- The cryptographic processor supports following standards:
- (#) The data encryption standard (DES) and Triple-DES (TDES) supported only by CRYP1 IP:
- (##)64-bit data block processing
- (##) chaining modes supported :
- (+++) Electronic Code Book(ECB)
- (+++) Cipher Block Chaining (CBC)
- (##) keys length supported :64-bit, 128-bit and 192-bit.
- (#) The advanced encryption standard (AES) supported by CRYP1 & TinyAES IP:
- (##)128-bit data block processing
- (##) chaining modes supported :
- (+++) Electronic Code Book(ECB)
- (+++) Cipher Block Chaining (CBC)
- (+++) Counter mode (CTR)
- (+++) Galois/counter mode (GCM/GMAC)
- (+++) Counter with Cipher Block Chaining-Message(CCM)
- (##) keys length Supported :
- (+++) for CRYP1 IP: 128-bit, 192-bit and 256-bit.
- (+++) for TinyAES IP: 128-bit and 256-bit
- [..] This section describes the AES Galois/counter mode (GCM) supported by both CRYP1 IP:
- (#) Algorithm supported :
- (##) Galois/counter mode (GCM)
- (##) Galois message authentication code (GMAC) :is exactly the same as
- GCM algorithm composed only by an header.
- (#) Four phases are performed in GCM :
- (##) Init phase: IP prepares the GCM hash subkey (H) and do the IV processing
- (##) Header phase: IP processes the Additional Authenticated Data (AAD), with hash
- computation only.
- (##) Payload phase: IP processes the plaintext (P) with hash computation + keystream
- encryption + data XORing. It works in a similar way for ciphertext (C).
- (##) Final phase: IP generates the authenticated tag (T) using the last block of data.
- (#) structure of message construction in GCM is defined as below :
- (##) 16 bytes Initial Counter Block (ICB)composed of IV and counter
- (##) The authenticated header A (also knows as Additional Authentication Data AAD)
- this part of the message is only authenticated, not encrypted.
- (##) The plaintext message P is both authenticated and encrypted as ciphertext.
- GCM standard specifies that ciphertext has same bit length as the plaintext.
- (##) The last block is composed of the length of A (on 64 bits) and the length of ciphertext
- (on 64 bits)
- [..] This section describe The AES Counter with Cipher Block Chaining-Message
- Authentication Code (CCM) supported by both CRYP1 IP:
- (#) Specific parameters for CCM :
- (##) B0 block : According to NIST Special Publication 800-38C,
- The first block B0 is formatted as follows, where l(m) is encoded in
- most-significant-byte first order(see below table 3)
- (+++) Q: a bit string representation of the octet length of P (plaintext)
- (+++) q The octet length of the binary representation of the octet length of the payload
- (+++) A nonce (N), n The octet length of the where n+q=15.
- (+++) Flags: most significant octet containing four flags for control information,
- (+++) t The octet length of the MAC.
- (##) B1 block (header) : associated data length(a) concatenated with Associated Data (A)
- the associated data length expressed in bytes (a) defined as below:
- (+++) If 0 < a < 216-28, then it is encoded as [a]16, i.e. two octets
- (+++) If 216-28 < a < 232, then it is encoded as 0xff || 0xfe || [a]32, i.e. six octets
- (+++) If 232 < a < 264, then it is encoded as 0xff || 0xff || [a]64, i.e. ten octets
- (##) CTRx block : control blocks
- (+++) Generation of CTR1 from first block B0 information :
- equal to B0 with first 5 bits zeroed and most significant bits storing octet
- length of P also zeroed, then incremented by one ( see below Table 4)
- (+++) Generation of CTR0: same as CTR1 with bit[0] set to zero.
- (#) Four phases are performed in CCM for CRYP1 IP:
- (##) Init phase: IP prepares the GCM hash subkey (H) and do the IV processing
- (##) Header phase: IP processes the Additional Authenticated Data (AAD), with hash
- computation only.
- (##) Payload phase: IP processes the plaintext (P) with hash computation + keystream
- encryption + data XORing. It works in a similar way for ciphertext (C).
- (##) Final phase: IP generates the authenticated tag (T) using the last block of data.
- *** Callback registration ***
- =============================================
- The compilation define USE_HAL_CRYP_REGISTER_CALLBACKS when set to 1
- allows the user to configure dynamically the driver callbacks.
- Use Functions @ref HAL_CRYP_RegisterCallback() or HAL_CRYP_RegisterXXXCallback()
- to register an interrupt callback.
- Function @ref HAL_CRYP_RegisterCallback() allows to register following callbacks:
- (+) InCpltCallback : Input FIFO transfer completed callback.
- (+) OutCpltCallback : Output FIFO transfer completed callback.
- (+) ErrorCallback : callback for error detection.
- (+) MspInitCallback : CRYP MspInit.
- (+) MspDeInitCallback : CRYP MspDeInit.
- This function takes as parameters the HAL peripheral handle, the Callback ID
- and a pointer to the user callback function.
- Use function @ref HAL_CRYP_UnRegisterCallback() to reset a callback to the default
- weak function.
- @ref HAL_CRYP_UnRegisterCallback() takes as parameters the HAL peripheral handle,
- and the Callback ID.
- This function allows to reset following callbacks:
- (+) InCpltCallback : Input FIFO transfer completed callback.
- (+) OutCpltCallback : Output FIFO transfer completed callback.
- (+) ErrorCallback : callback for error detection.
- (+) MspInitCallback : CRYP MspInit.
- (+) MspDeInitCallback : CRYP MspDeInit.
- By default, after the @ref HAL_CRYP_Init() and when the state is HAL_CRYP_STATE_RESET
- all callbacks are set to the corresponding weak functions :
- examples @ref HAL_CRYP_InCpltCallback() , @ref HAL_CRYP_OutCpltCallback().
- Exception done for MspInit and MspDeInit functions that are
- reset to the legacy weak function in the @ref HAL_CRYP_Init()/ @ref HAL_CRYP_DeInit() only when
- these callbacks are null (not registered beforehand).
- if not, MspInit or MspDeInit are not null, the @ref HAL_CRYP_Init() / @ref HAL_CRYP_DeInit()
- keep and use the user MspInit/MspDeInit functions (registered beforehand)
- Callbacks can be registered/unregistered in HAL_CRYP_STATE_READY state only.
- Exception done MspInit/MspDeInit callbacks that can be registered/unregistered
- in HAL_CRYP_STATE_READY or HAL_CRYP_STATE_RESET state,
- thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
- In that case first register the MspInit/MspDeInit user callbacks
- using @ref HAL_CRYP_RegisterCallback() before calling @ref HAL_CRYP_DeInit()
- or @ref HAL_CRYP_Init() function.
- When The compilation define USE_HAL_CRYP_REGISTER_CALLBACKS is set to 0 or
- not defined, the callback registration feature is not available and all callbacks
- are set to the corresponding weak functions.
