4.4. CMOX CCM PUBLIC METHODS

group CMOX_CCM_PUBLIC_METHODS

Functions

cmox_cipher_handle_t * cmox_ccm_construct ( cmox_ccm_handle_t * P_pThis , cmox_ccm_impl_t P_impl )

CCM constructor.

The function is used for specifying which block cipher algorithm to use in order to implement the CCM algorithm and if the algorithm will be used for encryption or decryption.

Parameters :

• P_pThis – Pointer to the CCM handle to initialize

• P_impl – Constant that specifies the implementation to use. This parameter can be one of the following values:

  • CMOX_AESFAST_CCM_ENC

  • CMOX_AESFAST_CCM_DEC

  • CMOX_AESSMALL_CCM_ENC

  • CMOX_AESSMALL_CCM_DEC

Returns :

cmox_cipher_handle_t* Pointer to a general cipher handle. This will be used by the general purpose cipher functions in order to perform the algorithm

4.5. CMOX CCM PUBLIC TYPES

group CMOX_CCM_PUBLIC_TYPES

Typedefs

typedef const struct cmox_ccm_implStruct_st * cmox_ccm_impl_t

CCM mode implementation.

This type specifies the used block cipher for the CCM construct and if the algorithm will be used for encryption or decryption. This type is defined as a pointer to a structure, that contains the functions needed for the specific implementation, defined in the library internally

struct cmox_ccm_handle_t

#include <cmox_ccm.h>

CCM handle structure.
