ECC provides stronger security and increased performance: it offers better protection than currently adopted encryption methods, but uses shorter key lengths (e.g. 256 bit ECC key provides the same level of security as 3,072 RSA key). The result? Stronger security that can handle the explosion in mobile device and tablet connections.
Requires fewer server processing cycles, allowing for more simultaneous SSL connections and faster processing. ECC key lengths increase at a slower rate than other encryption method keys as security levels increase, potentially extending the life of your existing hardware and giving you a greater return on your investment.
Symantec's ECC certificate roots have been in place for over five years: You can be confident that your ECC certificate will work throughout your ecosystem.
US Government approved: ECC is FIPS-certified (US Federal Information Processing Standard) and endorsed by the US National Security Agency.
