摘要：Cryptography plays very important role in security of data. Cryptography means to transfer sensitive information across insecure networks like internet so that it cannot be read by anyone except the person whom we want to send it. It basically hides the information. The federal organization used the Data Encryption Standard (DES) and the Triple Data Encryption Algorithm (TDEA) which may be used to protect sensitive data. Cryptography algorithms are divided into Symmetric and Asymmetric key cryptography. Symmetric Cryptography is further divided into Block Ciphers and Stream ciphers. T his paper discusses Performance Analysis of different block cipher algorithms (DES, 3DES, BLOWFISH) of Symmetric Key Cryptography. The algorithms uniquely define the mathematical steps required to transform data into a cryptographic cipher and also to tran sform the cipher back to the original form. A comparison has been conducted for those encryption algorithms at different settings for each algorithm such as different sizes of data blocks, different data types, battery power consumption, different key size and finally encryption/decryption speed. Simulation results are given to demonstrate the effectiveness of each algorithm. Simulation has been conducted by using .Net frame work and C# language
