10 / 43 page Functional overview UM0932 10/43 DocID17385 Rev 3 Table 3 lists the fields of DL frame. 3. Security services (SS) frames, providing authentication to payload using cryptographic algorithms based on AES with 128-bit keys. Authentication is provided appending to user data an AES-CMAC digest. A dedicated key (stored in the MIB object SS key 02h, Section 4.2.3) is used for both transmitting and receiving frames. Figure 4 shows the SS frame structure. Figure 4. Security services frame structure Table 4 lists the fields of SS frame. Table 3. DL frame description Field name Length Description and values DL length 1 Total length of payload and CRC fields. Payload DL length – length of CRC Data bytes CRC 1, 2 or 4 CRC calculated in accordance with algorithm chosen in dedicated MIB object (modem configuration 00h, Section 4.2.1). Table 4. SS frame description Field name Length Description and values Header HL Part of user data transmitted in clear. Encrypted payload LEN-29-HL Part of user data transmitted ciphered. IV 12 Initialization vector of AES-CTR algorithm. HL 1 Header field length. Digest 16 AES-CMAC digest computed on header, encrypted payload, IV and HL fields. |
