Asymmetric encryption is designed to protect data and key exchanges over open, insecure channels. The aim of asymmetric key encryption is to provide a method for securely encrypting data across public channels, in addition to authentication and data integrity. The sending computer encrypts the secret data using the receiving computer's public key and a mathematical operation. The power of public key encryption is in that mathematical operation. It's a "one-way function", which means it's incredibly difficult for a computer to reverse the operation and discover the original data. Digital Signing: Asymmetric encryption is much better for digital signing, compared to symmetric encryption. The use of both a public and private key means the identity of the signer of the data can easily be known. The signer uses their private key for encryption, while the recipient verifies their identity with their public key.Elliptical curve cryptography (ECC) is a public key encryption technique based on elliptic curve theory that can be used to create faster, smaller and more efficient cryptographic keys.
