Asymmetric Ciphers Flashcards
1
Q
RSA
A
- leverages prime number characteristics, 1024-4096 bit variable key size, 1 round
- most popular
- provides authentication and encryption
- authentication through digital signatures
2
Q
ECC
A
- leverages discrete logarithm characteristics, faster than RSA and uses less resources
- used in smaller devices like smartphones
- authentication and encryption
- authentication through digital signatures
3
Q
El Gamal
A
- used in recent versions of PGP
- extension of Diffie Hellman
- similar level of protection as RSA/ECC
- typically the slowest
4
Q
DSA
A
-Federal Information Processing Standard for digital signatures (FIPS 186)
5
