Robert has two cryptographic keys, and he needs to determine which of them is less prone to being attacked. The cryptoperiod is limited and equal for both the keys. The first key has a length of 2 and uses 16 characters, while the other key has a length of 3 and uses 15 characters. Which of the following is the best conclusion for Robert to come to?
a. Both the keys are equally secure.
b. The first key is more secure than the second key.
c. Neither of the keys are secure because they both have a limited cryptoperiod.
d. The second key is more secure than the first key.
d. The second key is more secure than the first key.

Sagot :

D. Compared to the first key, the second key is more secure.

Which of the various kinds of cryptographic algorithms can be used to guarantee a message's integrity?

The following uses symmetric key algorithms: encrypting and decrypting data with the same key ensures data confidentiality. Giving Message Confirmation Codes (Macintoshes) for source and respectability verification administrations.

Which cryptographic algorithm is capable of protecting the integrity or confidentiality of data?

The Rivest-Shamir-Adleman (RSA) algorithm has grown in popularity as an asymmetric encryption method because of this property. RSA assists businesses in ensuring the authenticity, confidentiality, integrity, non-repudiation, and integrity of information while it is in storage or transit.
