Elliptical Curve Cryptography (ECC)

Elliptical curve cryptography is a technique that uses an elliptical curve equation to create cryptography keys; keys generated by this theory are much smaller, faster, and efficient, as well! This modern technique keeps the decryption key private, while the encryption key is public. Unlike traditional methods of generating cryptography keys such as RSA, elliptical curve technique uses discrete algorithms making it difficult to decipher the keys or challenge the keys.

Eradication is an important function of the incident management process that follows the containment of an incident.
