Speeding up secure web transactions using Elliptic Curve Cryptography
2 likes1,218 views
This document contains graphs and data comparing the performance of different cryptographic algorithms for HTTPS requests. The graphs show that Elliptic Curve Cryptography (ECC) algorithms ECC-160 and ECC-224 have faster request handling times, lower first-response times, and can support more requests per second than the RSA algorithms RSA-1024 and RSA-2048, especially as the reuse of SSL sessions increases.
