Total questions: 10
Worksheet time: 5mins
Which of the following is primarily used to generate a digital signature?
Symmetric key algorithm
Asymmetric key algorithm
Hashing algorithm only
Steganography techniques
In cloud security, digital signatures help in achieving which of the following security goals?
Confidentiality only
Integrity and Non-repudiation
Authentication only
Availability only
What is typically used along with a digital signature to ensure message integrity?
Random number generator
Message digest (hash function)
Stream cipher
Session key
In cloud environments, digital signatures can be used for:
Secure boot processes
Code signing for applications
Authentication of API requests
All of the above
Which one of the following algorithms is commonly used for digital signatures in cloud security?
AES
SHA-256
RSA
Diffie-Hellman
Which key is used to sign a message in a digital signature scheme?
Sender's private key
Sender's public key
Receiver's private key
Receiver's public key
When verifying a digital signature, the verifier uses:
Sender's public key
Receiver's public key
Symmetric key shared between sender and receiver
Hash of the message only
Digital signatures in cloud storage help to:
Encrypt stored data
Authenticate users only
Detect unauthorized modifications to stored data
Improve storage capacity
In digital signature verification, what happens if the hash value of the original message and the hash value from the digital signature do not match?
The message is considered authentic
The message is rejected as tampered
The digital signature is re-generated automatically
Nothing happens; verification continues
Which standard is widely used for implementing digital signatures in cloud security?
SSL/TLS
X.509
IPsec
OAuth
