Which of the following statement is true for RSA algorithm ?
Answers
Explanation:
3 and 4 are correct. 3DES is a modified version the DES-algorithm (dates Encryption standard), which was introduced in 1974 and became ANSI-standard. Up to now, no weakness could be found except the insufficient length of the key (8 bytes, expanded to 32 bytes in 3DES). RC5 was thought as a successor for DES and is considered to be secure. Also IDEA (internationally dates Encryption Algorithm) could be a successor for DES. So far it hasn't been cracked, but its security is still disputed because it hasn't been tested properly yet.
RSA was developed 1977 and is used in PGP, for example.
2. Assymmetric Encryption
Answer:
Whitfield Diffie and Martin Hellman proposed the notion of public-key (also, more generally, called asymmetric key) cryptography in which two different but mathematically related keys are used—a public key and a private key.
