aes192CcmEncrypt is CCM encryption mode with AES-192 single block cipher.
The algorithm reference is: “Recommendation for Block Cipher Modes of Operation: The CCM Mode for Authentication and Confidentiality” The implementation is modified for better performance.
Parameters:
| _t | Length of the MAC in byte, t is an element of {4, 6, 8, 10, 12, 14, 16}. |
| _q | Length in byte of the binary representation of the length of the payload in byte, q is an element of {2, 3, 4, 5, 6, 7, 8}. |
| payloadStrm | Input block stream text to be encrypted. |
| cipherkeyStrm | Input cipher key used in encryption. |
| nonceStrm | The nonce stream. |
| ADStrm | Associated data stream. |
| lenADStrm | Length of associated data in byte. |
| lenPldStrm | Length of payload in byte. |
| endLenStrm | Flag to signal the end of the length streams. |
| cipherStrm | Output encrypted block stream text. |
| lenCphStrm | Length of cipher in byte. |
| tagStrm | The MAC stream. |
| endTagStrm | Flag to signal the end of the MAC stream. |
