The principal goal to design any encryption algorithm must be the security against unauthorized access or attacks. Data Encryption Standard (DES) algorithm is a symmetric key algorithm and it is used to secure the data. Enhanced DES algorithm works on increasing the key length or complex S-BOX design or increased the number of states in which the information is to be represented or combination of above criteria. By increasing the key length, the number of combinations for key will increase which is hard for the intruder to do the brute force attack. As the S-BOX design will become the complex there will be a good avalanche effect.
