How this entity was disambiguated

This entity first appeared as the object of triple T452331 — 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: Transparent Data Encryption
Context triple: [SQL Server, supportsFeature, Transparent Data Encryption]

A. Probabilistic Encryption
Probabilistic Encryption is a cryptographic technique that uses randomness in the encryption process so that the same message encrypts to different ciphertexts, enhancing security against attackers.
B. Advanced Encryption Standard
Advanced Encryption Standard is a widely used symmetric block cipher standard that secures digital data in applications ranging from wireless networks to government communications.
C. New Directions in Cryptography
New Directions in Cryptography is a landmark 1976 paper that introduced the concepts of public-key cryptography and digital signatures, fundamentally reshaping modern cryptography and secure communications.
D. Temporal Key Integrity Protocol
Temporal Key Integrity Protocol (TKIP) is a legacy wireless security algorithm designed to enhance WEP encryption in early Wi‑Fi networks by dynamically changing encryption keys.
E. IEEE 802.1AE MACsec standard
The IEEE 802.1AE MACsec standard is a network security protocol that provides data confidentiality, integrity, and origin authenticity for Ethernet traffic at the media access control (MAC) layer.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
