The cryptographic algorithm is designed toenhance security in real life with increased speed and lessmemory utilization. TEA is a kind of Feistel cipher whichuses simple operations like XOR, ADD, Shift. AES iscombined with segmentation and validation algorithm toimprove the performance of the security. Also, Keyexpansion is done to make the AES more secure. Theprocesses are pipelined to increase the speed of AES. Thispaper presents a hybrid approach in which the responsetime is minimized. The data is encrypted using AES andTiny Encryption Process. The hybrid Procedure isconsidered for easiness and improved performance. Atencryption time, data is encoded using tiny-AES-128encryption process which modifies it into an unreadabletext. Encryption of data is done using all four AES stepswith a little modification in S-Box used by substitute bytestep. Identities for S-box are created by applying theconcept of TEA which will be used during decryption. Ourproposed approach will minimize computational time andmemory utilization It is simulated in MATLAB 2014Ra.
