Abstract	Nowadays, Wi-Fi is a very popular Technology. Faster data transfer and Security both are very important for Wi-Fi. At present, Advanced Encryption Standard (AES) is used for Wi-Fi that is more secured than other encryption algorithms but it is not so fast because of it's complex functions. On the other hand, Blowfish is a very faster encryption algorithm but it cannot apply on Wi-Fi because of it's security problems. In this paper, a hybrid algorithm of Blowfish and Rivest Cipher 6 (RC6) is proposed that solves the security problems of Blowfish and also maintains the fastness of Blowfish and makes it able to use it in place of AES. It uses two innovative criteria. One is ingenious confusion process using two random numbers "a" and "w" that removes reflectively weak key attack and Known plaintext attack of Blowfish. The other is usage of one S-Box by overlapping process that eliminates the collision key attack of Blowfish. Sub key generation process of this algorithm also removes the Brute Force attack of AES. This paper tries to give an efficient algorithm that enhances the performance of Blowfish algorithm by adding a function of RC6 with it. The adding process is trickily handed here that makes the proposed algorithm as fast as Blowfish and also secured like existing AES. The proposed algorithm takes less encryption –decryption time like Blowfish and also secured like AES. Throughput, Average time for different data lengths and attack removal process are used to measure the efficiency of this proposed algorithm.
