| comp., MS | elliptic curve cryptography | criptografia de curva elíptica (An approach to public key cryptography based on properties of elliptic curves. The primary advantage of ECC is efficiency, which becomes important as devices get smaller and security requirements get more demanding. For example, ECC keys between 163 bits and 512 bits are one-sixth to one-thirtieth the size of equivalent security-level RSA keys. As key size increases the relative efficiency of ECC increases) |
| comp., MS | elliptic curve Diffie-Hellman | Diffie-Hellman de curva elíptica (Pertaining to a key agreement protocol which enables two users to create a shared secret agreement over a nonsecure, public medium, using elliptic curve cryptography without having previously exchanged any private information using. It is based on the Diffie–Hellman protocol) |
