Cryptographic Assessment

Assessment of cryptographic systems.

Cryptographic Assessment is the process of evaluating cryptographic systems to ensure they are secure and provide confidentiality, integrity, and availability of data. The assessment involves analyzing the cryptographic algorithms, key management, and implementation of crypto systems to identify any weaknesses or vulnerabilities.

Question 1

What is a certificate authority?

Correct Answer: A trusted entity that issues digital certificates and verifies the identity of the certificate owner.

A certificate authority is a trusted entity that issues digital certificates and verifies the identity of the certificate owner. The certificate authority verifies the identity of the certificate owner by checking the information in the certificate against public records or by having the certificate owner provide additional identification information. Once a certificate has been issued by a certificate authority, it can be used to verify the identity of the certificate owner.

Question 2

What is a symmetric key algorithm?

Correct Answer: A cryptographic algorithm that uses the same key for encryption and decryption.

Symmetric key algorithms use the same key for both encryption and decryption. This means that the same key used to encrypt the data is used to decrypt it. Examples include AES and DES.

Question 3

What is a substitution cipher and how does it work?

Correct Answer: A cipher that replaces one letter or symbol with another

A substitution cipher is a type of encryption where each letter or symbol in the plaintext is replaced with another letter or symbol according to a fixed rule. For example, in the Caesar cipher, each letter is shifted by a fixed number of positions. In the monoalphabetic substitution cipher, each letter is replaced with a corresponding letter from a fixed alphabet. This type of cipher is vulnerable to frequency analysis attacks, where an attacker can analyze the frequency of letters in the ciphertext to deduce the key.
