Encryption algorithm plays a crucial role in information security which guarantees the recent growing internet and network applications. They are used to secure the data in wireless networks against malicious attacks but securing data also consumes resources such as C.P.U time, Memory, battery power, encryption time etc. In this paper, the authors evaluated the performance of four symmetric key encryption algorithms; AES, DES, 3DES and Blowfish which commonly used for data encryption in terms of encryption time, decryption time & throughput. In this paper, they evaluated encryption time, decryption time and throughput for all four encryption algorithms in Visual Basic's environment using large size text data (.doc).
