name: MAC-I
full_form: MAC used for data integrity of signalling messages
context: the MAC-I truncated to the correct size from the right. If 128-EIA1 is indicated in the HSE BEST protocol ID element, then the algorithm specified in 3GPP TS 33.401[12] Annex B.2.2 shall be used to generate the MAC-I value. The MAC shall be set to the MAC-I truncated to the correct size from the right. If 128-EIA2 is indicated in the HSE BEST protocol ID element, then the algorithm specified in 3GPP TS 33.401[12] annex B.2.3 shall be used to generate the MAC-I value. The MAC shall be set to the MAC-I truncated to the correct size from the right. If 128-EIA3 is indicated in the HSE BEST protocol ID element, then the algorithm specified in 3GPP TS 35.221 [10] shall be used to generate the MAC-I value. The MAC shall be set to the calculated MAC-I value truncated to the correct size from the right. If 128-NIA1 is indicated in the HSE BEST protocol ID element, then the algorithm specified in 3GPP TS 33.401[12] Annex B.2.2 shall be used to generate the MAC-I value. The MAC shall be set to
description: MAC-I is a Message Authentication Code used to ensure the integrity of signaling messages in telecommunications networks. It operates within protocols like HSE BEST and EMSDP to protect against unauthorized modifications during transmission.
explanation: The description explicitly mentions MAC-I's function as a Message Authentication Code, designed to verify the integrity of signaling messages, placing it firmly within the category of Message Authentication Codes.
