Abstract: Nowadays security is very important to protect our sensitive information in computer or over the internet such as in online banking, online shopping, stock market and bill payments etc. Without security our information exchanged over internet are not safe. Encryption Algorithms provides the security to the information which is exchanged over the internet. In this project we are proposing a new cryptographic algorithm AEDS (Advanced Encryption and Decryption Standard) which is developed by combining properties of DES and AES algorithms. Then we compared all these three algorithms and we found that AEDS is more secure and robust for data security.
