ECC to replace RSA

This article reports that NSA is pushing to migrate over from RSA to ECC (Elliptic Curve Cryptography). RSA is nearly 30 yrs old and still a 1024 bit RSA key is unbreakable. Although quantum computing has the potential to solve the Integer Factorization and thereby break RSA, we need to have the quantum computing concept materialize for use. Anywayz plans are on to migrate all assymetric encryptions to use ECC starting 2010 and ECC would become the NIST (National Institute of Standards and Technology) standard.
Excerpt from the report --
ECC, a complex mathematical algorithm used to secure data in transit, will replace RSA and Diffie-Hellman because it can provide much greater security at a smaller key size. ECC takes less computational time and can be used to secure information on smaller machines, including cell phones, smart cards and wireless devices.

Gud that ECC requires smaller keys and is fast.
