Asymmetric Systems

–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.

 

[bs_icon name=”glyphicon glyphicon-chevron-right”]  Types of Asymmetric Systems

• The Diffie-Hellman Algorithm
• RSA
• El Gamal
• Elliptic Curve Cryptosystems
• LUC
• Knapsack
• Zero Knowledge Proof

[bs_icon name=”glyphicon glyphicon-chevron-right”]  Symmetric Systems

–Uses a shared secret key for encryption and decryption

–Based on mathematical transposition and substitution functions

–Faster than asymmetric and hard to break.

–Examples below:

• Data Encryption Standard (DES)
• Triple-DES
• Advance Encryption Standard (AES)
• International Data Encryption Algorithm (IDEA)
• Blowfish
• RC4
• RC5
• RC6
