What are the possible approaches to defeating RSA algorithm?

15 ways to break RSA security

• Small factors.
• Fermat factorization.
• Batch GCD.
• Elliptic Curve Method (ECM)
• Weak entropy.
• Smooth p-1 or p+1.
• Fault injection.
• Small private exponent.

How Timing attacks are performed on RSA algorithm discuss approaches to overcome these attacks?

For a timing attack, the attacker needs to have the target system compute Cd mod N for several carefully selected values of C. By precisely measuring the amount of time required and analyzing the timing variations, the attacker can recover the private key d one bit at a time until the entire exponent is known.

What are the possible attacks on DES?

There are three attacks known that can break the full 16 rounds of DES with less complexity than a brute-force search: differential cryptanalysis (DC), linear cryptanalysis (LC), and Davies’ attack. To break the full 16 rounds, differential cryptanalysis requires 247 chosen plaintexts.

Why do we use RSA algorithm?

The RSA algorithm (Rivest-Shamir-Adleman) is the basis of a cryptosystem — a suite of cryptographic algorithms that are used for specific security services or purposes — which enables public key encryption and is widely used to secure sensitive data, particularly when it is being sent over an insecure network such as …

How do timing attacks work?

In cryptography, a timing attack is a side-channel attack in which the attacker attempts to compromise a cryptosystem by analyzing the time taken to execute cryptographic algorithms. Information can leak from a system through measurement of the time it takes to respond to certain queries. …

What type of attacks are possible on Triple DES?

Triple DES is also vulnerable to meet-in-the middle attack because of which it give total security level of 2^112 instead of using 168 bit of key. The block collision attack can also be done because of short block size and using same key to encrypt large size of text. It is also vulnerable to sweet32 attack.

What is the vulnerability of the standard DES encryption algorithm?

The Data Encryption Standard (DES) is susceptible to brute-force attacks, which are well within the reach of a modestly financed adversary.
