CRYPTOGRAPHY BOARD EVALUATION
2026 GUARANTEED PASS ANSWERS
GRADED A+
●● Integrity. Answer: Guarding against improper information
modification or destruction to ensure authenticity.
●● Authentication. Answer: Verifying the identity of a user, process, or
device before allowing access to a system.
●● Non-repudiation. Answer: Providing assurance that the sender gets
proof of delivery and the recipient gets proof of the sender's identity,
preventing either from denying the action.
●● Data at Rest. Answer: Stored data residing in a permanent location
awaiting access, such as hard drives or cloud storage.
●● Data in Motion. Answer: Data being transmitted across a network
between two systems.
●● Data in Use. Answer: Data stored in the active memory of a
computer system where it is accessed by a running process.
, ●● Algorithm. Answer: A repeatable mathematical process that produces
the same result when it receives the same input.
●● Cipher. Answer: A specific algorithm used to encrypt or decrypt
information.
●● Key. Answer: A value used to control cryptographic operations like
encryption, decryption, or signature generation.
●● Keyspace. Answer: The set of all possible keys for a given
cryptographic algorithm.
●● Brute-Force Attack Reality. Answer: When guessing keys, an
attacker will generally find the correct key halfway through searching
the entire keyspace.
●● One-Way Function. Answer: A mathematical operation that easily
produces an output for any given input, but makes it impossible to
reverse-engineer the input from the output.
●● Nonce. Answer: A randomly generated number used as a one-time
placeholder variable in mathematical functions.
