FREE ISSAP Cryptography Questions and Answers

To ensure user accountability

To enforce authentication policies

To protect confidentiality, integrity, and authenticity of data

To prevent denial-of-service attacks

Correct! Wrong!

Cryptography provides mechanisms to secure data by ensuring its confidentiality, integrity, and authenticity during transmission or storage.

Public key infrastructure (PKI)

Asymmetric cryptography

Hash functions

Symmetric cryptography

Correct! Wrong!

Symmetric cryptography uses the same key for both encryption and decryption, making it fast but requiring secure key management.

To encrypt data

To verify the authenticity and integrity of a message

To generate a session key

To ensure anonymity

Correct! Wrong!

Digital signatures provide assurance that the message comes from the claimed sender and has not been altered in transit.

RSA (Rivest-Shamir-Adleman)

AES (Advanced Encryption Standard)

DES (Data Encryption Standard)

3DES (Triple DES)

Correct! Wrong!

RSA is an asymmetric algorithm that uses a pair of keys (public and private) for encryption and decryption.

To encrypt and decrypt data

To create a unique fixed-length representation of data

To generate keys for encryption

To facilitate secure communication

Correct! Wrong!

Hash algorithms produce a fixed-length hash value from input data, ensuring data integrity by detecting alterations.
