  4. How do elliptic curve cryptosystemscompare with other cryptosystems? • Roughly speaking, elliptic curve cryptosystems with a 160-bit key offer about the same security as RSA and discrete logarithm based systems with a 1024-bit key. As a result, the length of the public key and private key is much shorter in elliptic curve cryptosystems. • Elliptic curve cryptosystems are faster than the RSA system in signing and decryption, but slower in signature verification and encryption. • Reference: http://www.rsa.com/rsalabs/node.asp?id=2245
