WebOct 23, 2013 · If you just want the gist, the TL;DR is: ECC is the next generation of public key cryptography and, based on currently understood mathematics, provides a significantly more secure foundation than first generation public key cryptography systems like RSA. WebThe most important difference of ECC compared to RSA is the key size in relation to the cryptographic resistance. ECC provides the same cryptographic strength as the RSA system, but with much smaller keys. For example, a 256-bit ECC key is the same as 3,072-bit RSA key (which are 50% longer than the 2,048-bit keys used for SSL certificates today).
