–Uses a pair of keys (private and public) for encryption and decryption
–Built upon hard-to-resolve mathematical problem using factorization, discreet logarithms, and the elliptic curve theory.
–Slower than symmetric algorithm.
Types of Asymmetric Systems

–Uses a shared secret key for encryption and decryption
–Based on mathematical transposition and substitution functions
–Faster than asymmetric and hard to break.
- Data Encryption Standard (DES)
- Advance Encryption Standard (AES)
