A Note on Key Strength
200 bits of Elliptic Curve Crypto is a lot
- Cracking a 193 bit ECC key would take 8.52*1014 MIPS years [Lenstra ’99]
- Or 1.89*1012 years on an Intel 450Mhz PII
TCP hijacking with IP spoofing is easier
TCP alone is inherently insecure
- Real security requires end host authentication and strong session keys
