Encryption of small values, such as identifiers or names, is made complicated by the possibility of __________

Dictionary attacks

Database attacks

Minor attacks

Random attacks

Discuss

Answer: (a).Dictionary attacks

Q102.

Which one of the following uses a 128bit round key to encrypt the data using XOR and use it in reverse to decrypt it ?

Round key algorithm

Public key algorithm

Advanced Encryption Standard

Asymmetric key algorithm

Discuss

Answer: (c).Advanced Encryption Standard

Q103.

Which of the following requires no password travel across the internet ?

Readable system

Manipulation system

Challenge–response system

Responce system

Discuss

Answer: (c).Challenge–response system

Q104.

Assymmetric Encryption: Why can a message encrypted with the Public Key only be decrypted with the receiver’s appropriate Private Key?

Not true, the message can also be decrypted with the Public Key

A so called “one way function with back door” is applyed for the encryption

The Public Key contains a special function which is used to encrypt the message and which can only be reversed by the appropriate Private Key

The encrypted message contains the function for decryption which identifies the Private Key

Discuss

Answer: (b).A so called “one way function with back door” is applyed for the encryption

Q105.

Which is the largest disadvantage of the symmetric Encryption?

More complex and therefore more time-consuming calculations

Problem of the secure transmission of the Secret Key

Less secure encryption function

Isn’t used any more

Discuss

Answer: (b).Problem of the secure transmission of the Secret Key

Q106.

Which is the principle of the encryption using a key?

The key indicates which funcion is used for encryption. Thereby it is more difficult to decrypt a intercepted message as the function is unknown

The key contains the secret function for encryption including parameters. Only a password can activate the key

All functions are public, only the key is secret. It contains the parameters used for the encryption resp. decryption

The key prevents the user of having to reinstall the software at each change in technology or in the functions for encryption

Discuss

Answer: (b).The key contains the secret function for encryption including parameters. Only a password can activate the key
