Encryption Advanced Quiz 3
1. What is a "Meet-in-the-Middle" attack?
Attempting to breach a computer terminal located within a busy public environment
A collaborative security method used to share a master password with a remote user
An attack reducing brute-force attempts required for multiple-encryption schemes
2. What is "Differential Cryptanalysis"?
Analyzing the physical hardware differences between two separate server clusters
Studying how input differences affect resultant output differences to find keys
A diagnostic way to recover a lost encryption key from a corrupted backup drive
3. What is "Poly1305"?
A high-speed MAC often used in conjunction with the ChaCha20 cipher algorithm
A heat-resistant type of polymer used in the construction of modern server racks
A legacy communication protocol designed for early generations of web servers
4. What is "Format-Preserving Encryption" (FPE)?
Encryption designed to significantly reduce the size of a data file for storage
An administrative tool used to convert a photo from one file format to another
Encryption where the output maintains the same format as the original data input
5. What is the "Fiat-Shamir Heuristic"?
A specialized security method used to drive and track autonomous car software
Transforming an interactive proof of knowledge into a non-interactive signature
A standardized administrative tool used for naming secure internal system files
6. What is "Integral Cryptanalysis"?
An attack effective on block ciphers based on substitution-permutation networks
Using advanced calculus to mathematically derive a hidden encryption session key
A method of combining two different cipher algorithms into one secure operation
7. What is a "Boomerang Attack"?
An unintended security event where an exploit hits the attacker instead of the target
Deploying a script that exfiltrates a password and returns it to the original sender
A cryptanalysis method that uses differential cryptanalysis to reach a middle point
8. What does "Semantic Security" mean?
An advanced type of encryption that understands the linguistic meaning of words
A property where an attacker gains no significant info about plaintext from ciphertext
A background process used for checking spelling errors within an encrypted data set
9. What is "Malleability" in a cipher?
An attacker transforming ciphertext into another that decrypts to related plaintext
The technical ability for a single encryption key to be shared across many devices
A configuration method used to make a cryptographic algorithm run at a faster speed
10. What is "IND-CPA"?
A diagnostic way to compare the technical strength of two different user passwords
A software tool used for finding and indexing duplicate files on a local hard drive
A security goal where an attacker cannot distinguish which plaintext was encrypted
