Question: Who is designated as the design authority for standardized cryptographic algorithms in 3GPP security specifications?
Option 1: 3GPP Security Working Group (TSG SA WG3)
Option 2: ETSI SAGE (European Telecommunications Standards Institute Security Algorithms Group of Experts)
Option 3: ITU-T Study Group 17 (Security)
Option 4: IETF Crypto Forum Research Group (CFRG)
Explanation: In the context of 3GPP security specifications, particularly for cryptographic algorithms requiring standardization, ETSI SAGE is entrusted with the design authority. This role leverages SAGE's specialized expertise in security algorithms, complemented by input from 3GPP partner organizations, to ensure robust and standardized cryptographic solutions for telecom networks.
