Q44 / 100
What is RSA encryption and what are its limitations?
Correct! Well done.
Incorrect.
The correct answer is B) An asymmetric cryptosystem based on the difficulty of factoring large integers, used for key exchange and signatures but too slow for bulk encryption
B
Correct Answer
An asymmetric cryptosystem based on the difficulty of factoring large integers, used for key exchange and signatures but too slow for bulk encryption
Explanation
RSA (Rivest-Shamir-Adleman) relies on factoring n=p*q being hard. Used for key encapsulation and signatures. Disadvantages: slow (1000x slower than AES), key size (2048-4096 bits needed), vulnerable to quantum (Shor's algorithm).
