Elliptic Curve Cryptography (ECC)
Elliptic Curve Cryptography (ECC) is an asymmetric encryption technique that provides strong security with smaller key sizes compared to RSA.
2
How ECC Works
ECC is based on the mathematics of elliptic curves over finite fields. It uses points on a curve to perform encryption and decryption operations.
3
Key Components
- Public Key: A point on the elliptic curve derived from the private key.
- Private Key: A randomly chosen number used for decryption.
4
Why ECC is Secure
- Relies on the difficulty of the elliptic curve discrete logarithm problem.
- Provides the same level of security as RSA with much smaller keys.
5
Advantages of ECC
- Requires smaller key sizes than RSA for the same security level.
- Faster computations and lower resource usage.
6
Disadvantages of ECC
- More complex mathematical operations.
- Potential vulnerabilities in poorly implemented systems.
7
Common ECC Algorithms
- ECDSA: Elliptic Curve Digital Signature Algorithm.
- ECDH: Elliptic Curve Diffie-Hellman for secure key exchange.

9
Use Cases
- Mobile devices and embedded systems due to low resource consumption.
- SSL/TLS certificates for secure web browsing.
- Cryptographic wallets for blockchain applications.
10
Summary
- Elliptic Curve Cryptography (ECC) is an efficient asymmetric encryption method.
- It provides strong security with smaller key sizes compared to RSA.
- ECC is widely used in mobile security, digital signatures, and key exchange.
