How GATE tests Network Security

Network Security in GATE CS is tested primarily through core concepts of public-key cryptography, digital signature protocols, and cryptographic attacks. Questions focus on the mechanics of asymmetric encryption (specifically RSA key generation and modular arithmetic) and the correct application of private/public keys for digital signing, message digests, and vulnerability analysis.
