Question: What is required for quality assurance of an algorithm specification before its delivery, according to 3GPP security standards?
Option 1: A single simulation of the algorithm verified against a set of predefined test cases.
Option 2: Two consecutive simulations of the algorithm on the same test data to ensure consistency.
Option 3: Two independent simulations of the algorithm, each confirmed against specifically designed test data for verifying key execution points.
Option 4: A joint simulation with another standardized algorithm to test interoperability.
Explanation: This option correctly reflects the requirement for ensuring the integrity and accuracy of an algorithm specification. Having two independent simulations, each validated against tailored test data, provides a robust quality assurance process. This approach helps in identifying any discrepancies or flaws in the specification before its delivery, thereby enhancing the reliability of the cryptographic algorithm in 3GPP security contexts, such as those involving User Equipment (UE) and network security protocols.
