What are attacks possible in rsa algorithm network security?
Answers
Answer:
Four possible approaches to attacking the RSA algorithm are
• Brute force: This involves trying all possible private keys.
• Mathematical attacks: There are several approaches, all equivalent in effort to factoring the product of two primes.
• Timing attacks: These depend on the running time of the decryption algorithm.
• Chosen ciphertext attacks: This type of attack exploits properties of the RSA algorithm.
The defense against the brute-force approach is the same for RSA as for other cryptosystems, namely, to use a large key space. Thus,the larger the number of bits in d, the better. However, because the calculations involved, both in key generation and inencryption/decryption, are complex,
the larger the size of the key, the slower the system will run.
In this subsection, we provide an overview of mathematical and timing attacks.
