How this entity was disambiguated

This entity first appeared as the object of triple T7032736 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07

Target entity: Intel Secure Key (RDRAND)
Context triple: [Goldmont, supports, Intel Secure Key (RDRAND)]

A. Intel AES-NI
Intel AES-NI is a set of hardware instructions introduced by Intel to accelerate and secure AES encryption and decryption operations in modern processors.
B. Blum–Blum–Shub pseudorandom number generator
The Blum–Blum–Shub pseudorandom number generator is a cryptographically secure generator based on the hardness of factoring large composite numbers, widely studied in theoretical computer science and cryptography.
C. Blum–Micali pseudorandom number generator
The Blum–Micali pseudorandom number generator is a foundational cryptographic algorithm that produces provably secure pseudorandom bits based on number-theoretic hardness assumptions.
D. Address Space Layout Randomization (ASLR)
Address Space Layout Randomization (ASLR) is a security technique that randomly arranges the memory addresses used by key data areas of a process to make it harder for attackers to predict and exploit them.
E. Intel SGX
Intel SGX is a hardware-based security technology that enables the creation of protected enclaves in memory to run sensitive code and data in isolation from the rest of the system.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
