DES (Data Encryption Standard) uses which type of encryption?

• Asymmetric

• Symmetric

• Hashing

• Quantum

DES is vulnerable due to its:

• 256-bit key

• Feistel network

• 56-bit key

• Substitution-permutation design

AES (Advanced Encryption Standard) is considered secure because it supports:

• 56-bit keys

• 128/192/256-bit keys

• MD5 hashing

• RC4 encryption

Which cryptographic hash function is deprecated due to collision vulnerabilities?

• SHA-256

• AES

• MD5

• HMAC

SHA-256 is commonly used in:

• Legacy systems

• Digital signatures and blockchain

• WEP encryption

• TCP handshakes

Non-repudiation is provided by:

• MAC

• Digital signatures

• CRC-32

• Base64 encoding

MAC (Message Authentication Code) requires:

• A public key

• A shared secret key

• A digital certificate

• A nonce

Digital certificates rely on the security of:

• The recipient’s private key

• The TCP protocol

• The Certificate Authority (CA)

• Firewall policies
