name: UTC
full_form: Universal Time Coordinated
context: It is proposed that in the context of scrambling, the UTC based counter is slowed down in order to make the system more efficient, and more persistent towards Denial-of-Service attacks while still making the tracking of ProSe UEs difficult for the attacker. NOTE 1: Masked UTC counter can be used as an input parameter to scrambling (solution in clause 8.3.15) or as an input parameter to key hint calculation (solution in clause 8.3.14). If used for scrambling, however, it would be better to have one or very few UTC masks for several UEs in the area in order to prevent the tracking being based on the frequencies of the masked UTC counters. This solution does not take a stand in which context it is used. The UTC based counter can be slowed down using a new UTC mask. The UTC mask is essentially hiding some least significant bits of the UTC based counter making the counter change its value less frequently. The masked UTC counter value is a bitwise AND operation between the UTC mask and the
description: UTC (Universal Time Coordinated) is a critical network attribute used in ProSe UE scrambling. It serves as an input parameter for either scrambling or key hint calculation. The UTC-based counter enhances system efficiency and resilience against Denial-of-Service attacks while making UE tracking difficult for attackers.
explanation: UTC is classified as a Parameter because it directly influences network operations, specifically in ProSe UE scrambling and key hint calculation. Its role as an input parameter and its manipulation through masking for security and efficiency purposes solidify its classification.
