Crypto, Authenticated Encryption with Symmetric key Verification Functions.

TEE_AEUpdate() - Accumulates data for an Authentication Encryption operation

This function describes Input data does not have to be a multiple of block size. Subsequent calls to this function are possible. Unless one or more calls of this function have supplied sufficient input data,no output is generated. when using this routine to decrypt the returned data may be corrupt since the integrity check is not performed until all the data has been processed. If this is a concern then only use the TEE_AEDecryptFinal routine.

Parameters

operation	Handle of a running AE operation.
srcData	Input data buffer to be encrypted or decrypted
srcLen	length of the input buffer.
destData	Output buffer
destLen	length of the out put buffer.

Returns: 0 on success.; TEE_ERROR_SHORT_BUFFER if the output buffer is not large enough to contain the output.

	)

Crypto, Authenticated Encryption with Symmetric key Verification Functions.

TEE_AEUpdateAAD() - Feeds a new chunk of Additional Authentication Data (AAD) to the AE operation. Subsequent calls to this function are possible.

The TEE_AEUpdateAAD function feeds a new chunk of Additional Authentication Data (AAD) to the AE operation. Subsequent calls to this function are possible.The buffers srcData and destData shall be either completely disjoint or equal in their starting positions.The operation SHALL be in initial state and remains in initial state afterwards.

Parameters

operation	Handle on the AE operation
AADdata	Input buffer containing the chunk of AAD
AADdataLen	length of the chunk of AAD.

◆ TEE_AllocateOperation()

TEE_Result TEE_AllocateOperation	(	TEE_OperationHandle *	operation,
		uint32_t	algorithm,
		uint32_t	mode,
		uint32_t	maxKeySize
	)

Crypto, for all Crypto Functions.

TEE_AllocateOperation() - Allocates a handle for a new cryptographic operation and sets the mode and algorithm type.

If this function does not return with TEE_SUCCESS then there is no valid handle value.Once a cryptographic operation has been created, the implementation shall guarantee that all resources necessary for the operation are allocated and that any operation with a key of at most maxKeySize bits can be performed. For algorithms that take multiple keys, for example the AES XTS algorithm, the maxKeySize parameter specifies the size of the largest key. It is up to the implementation to properly allocate space for multiple keys if the algorithm so requires.

Parameters

operation	reference to generated operation handle.
algorithm	One of the cipher algorithms.
mode	The operation mode.
maxKeySize	Maximum key size in bits for the operation.

Returns: 0 in case of success; TEE_ERROR_OUT_OF_MEMORY If there are not enough resources to allocate the operation.; TEE_ERROR_NOT_SUPPORTED If the mode is not compatible with the algorithm or key size or if the algorithm is not one of the listed algorithms or if maxKeySize is not appropriate for the algorithm.

TEE_Result TEE_AllocateTransientObject	(	TEE_ObjectType	objectType,
		uint32_t	maxKeySize,
		TEE_ObjectHandle *	object
	)

Crypto, Asymmetric key Verification Functions.

TEE_AllocateTransientObject() - Allocates an uninitialized transient object. Transient objects are used to hold a cryptographic object (key or key-pair).

The value TEE_KEYSIZE_NO_KEY should be used for maxObjectSize for object types that do not require a key so that all the container resources can be pre-allocated. As allocated, the container is uninitialized. It can be initialized by subsequently importing the object material,generating an object, deriving an object, or loading an object from the Trusted Storage.

Parameters

objectType	Type of uninitialized object container to be created
maxKeySize	Key Size of the object.
object	Filled with a handle on the newly created key container.

Returns: 0 on success; TEE_ERROR_OUT_OF_MEMORY If not enough resources are available to allocate the object handle.; TEE_ERROR_NOT_SUPPORTED If the key size is not supported or the object
type is not supported.

Returns: TEE_SUCCESS if success else error occured.

TEE_ReadObjectData() - Attempts to read size bytes from the data stream associated with the object object into the buffer pointed to by buffer.

The bytes are read starting at the position in the data stream currently stored in the object handle. The handle’s position is incremented by the number of bytes actually read. On completion TEE_ReadObjectData sets the number of bytes actually read in the uint32_t pointed to by count.

TEE_WriteObjectData() - Writes the buffer data in to persistent objects.

In this function it checks if object is present or not, the encryption/ decryption buffer is taken by calling mbedtls_aes_crypt_cbc() then that buffer data is encrypted and mapped to object.On the base of object creation TEE_SUCCESS appears else TEE_ERROR_GENERIC appears.

Parameters

object	Handle of the object
buffer	The buffer containing the data to be written
size	The number of bytes to write

Returns: TEE_SUCCESS if success else error occured.

TEE_WriteObjectData() - writes size bytes from the buffer pointed to by buffer to the data stream associated with the open object handle object.

If the current data position points before the end-of-stream, then size bytes are written to the data stream, overwriting bytes starting at the current data position. If the current data position points beyond the stream’s end, then the data stream is first extended with zero bytes until the length indicated by the data position indicator is reached, and then size bytes are written to the stream.

Parameters

object	Handle of the object
buffer	The buffer containing the data to be written
size	The number of bytes to write

Returns: TEE_SUCCESS if success else error occured.
