Which cryptographic key mechanism is used to decrypt data that was scrambled using a publicly distributed asymmetric encryption key? MCQ with Answer and Explanation
Which cryptographic key mechanism is used to decrypt data that was scrambled using a publicly distributed asymmetric encryption key?
A. Shared Symmetric Token
B. Public Key
C. Hash Digest Code
D. Private Key
Answer: Option D
Solution (By JKSSB Mock Tests)
Asymmetric cryptography pairs a public key (used by anyone to encrypt data) with a mathematically linked private key (kept secret by the recipient to decrypt the data).
Which process converts plain text data strings into unreadable ciphertext formats using mathematical cryptographic keys, securing files against unauthorized viewing?
Explanation:
Encryption alters readable data into ciphertext using cryptographic mathematical algorithms, requiring specialized keys to reverse and decode.
Which type of network security exploit uses a fake wireless router with the exact same SSID label as a corporate office network to trick workers into connecting so the attacker can log their data traffic?
Explanation:
An Evil Twin attack clones a legitimate Wi-Fi access point configuration to trick users into connecting, allowing the attacker to monitor network traffic.
What is the technical security term given to a software flaw or hardware vulnerability that is actively exploited by threat actors before the software vendor has developed a remediation patch?
Explanation:
A zero-day exploit targets unknown or unpatched software vulnerabilities, giving defense teams zero days of preparation to guard against the threat.
