Q21.

Why is reversing restricted algorithms not a good way to maintain secrecy?

Restricted algorithms are not used for cryptography.

Reversing can be used to break the algorithm since the secret is the algorithm itself.

Reversing is not effective against restricted algorithms.

None of the above

Discuss

Answer: (b).Reversing can be used to break the algorithm since the secret is the algorithm itself. Explanation:The secret in restricted algorithms is the algorithm itself, and reversing can be seen as a way to break the algorithm. Therefore, reversing is not a good way to maintain secrecy for restricted algorithms.

Q22.

What is the purpose of reversing private implementations of key-based ciphers?

To break the encryption algorithm.

To obtain the key.

To evaluate the overall level of security offered by a program.

None of the above

Discuss

Answer: (c).To evaluate the overall level of security offered by a program. Explanation:Specific implementation details can impact the overall level of security offered by a program, and the only way to know for sure whether a security product is truly secure is to either go through its source code or to reverse it.

Q23.

What is the difference between a restricted algorithm and a key-based algorithm?

A restricted algorithm is a type of key-based algorithm.

A restricted algorithm relies on the secrecy of the key while a key-based algorithm relies on the secrecy of the algorithm.

A key-based algorithm relies on the secrecy of the key while a restricted algorithm relies on the secrecy of the algorithm.

None of the above

Discuss

Answer: (c).A key-based algorithm relies on the secrecy of the key while a restricted algorithm relies on the secrecy of the algorithm. Explanation:Restricted algorithms rely on the secrecy of the algorithm itself, while key-based algorithms rely on the secrecy of the key used to encrypt and decrypt messages.

Q24.

What is cryptography based on?

Secrecy

Publicity

Accessibility

Openness

Discuss

Answer: (a).Secrecy Explanation:Cryptography has always been based on secrecy.

Q25.

How can cryptographic algorithms be divided?

Into restricted algorithms and key-based algorithms

Into open algorithms and closed algorithms

Into symmetric algorithms and asymmetric algorithms

Into public algorithms and private algorithms

Discuss

Answer: (a).Into restricted algorithms and key-based algorithms Explanation:Cryptographic algorithms can be roughly divided into two groups: restricted algorithms and key-based algorithms.

Q26.

What is the secret in restricted algorithms?

The algorithm itself

The key

The original message

The implementation details

Discuss

Answer: (a).The algorithm itself Explanation:The secret in restricted algorithms is the algorithm itself.

Q27.

Why do restricted algorithms provide poor security?

Because reversing makes it very difficult to maintain the secrecy of the algorithm

Because they are too complex to implement correctly

Because they are too simple to provide effective encryption

Because they rely on too many keys

Discuss

Answer: (a).Because reversing makes it very difficult to maintain the secrecy of the algorithm Explanation:Restricted algorithms provide very poor security because reversing makes it very difficult to maintain the secrecy of the algorithm.

Q28.

What is the secret in key-based algorithms?

The algorithm itself

The key

The original message

The implementation details

Discuss

Answer: (b).The key Explanation:In key-based algorithms, the secret is a key, some numeric value that is used by the algorithm to encrypt and decrypt the message.

Q29.

Are encryption algorithms always secure?

Yes

May be Yes or No

Can't say

Discuss

Answer: (b).No Explanation:Specific implementation details can often have an unexpected impact on the overall level of security offered by a program. Encryption algorithms are delicate, and minor implementation errors can sometimes completely invalidate the level of security offered by such algorithms.

Q30.

Are key-based algorithms usually made public or private?

Public

Private

Both

None

Discuss

Answer: (a).Public Explanation:The algorithms are usually made public, and the keys are kept private.
