compared to other networks. Moreover‚ each network continues to evolve individually‚ most frequently not in a coordinated manner with other networks‚ further reducing compatibility among these networks. An integrated security mechanism is one of the key challenges in the Open Wireless network Architecture (OWA) because of the diversity of the wireless networks in OWA and the unique security mechanism used in each one of these networks. The overall security of the network is as strong as its weakest

Premium Cryptography Cipher Key
INTRODUCTION: Blowfish‚ a symmetric block cipher developed by Bruce Schneier[SCHN93‚ SCHN94)‚ is a Feistel network‚ iterating simple encryption and decryption functions of 16 times each. The block size is 64 bits‚ and the key can be any length up to 448 bits. Although there is a complex initialization phase required before any encryption can take place‚ the actual encryption of data is very efficient on large microprocessors. Blowfish was designed to have the following characteristics: Fast:
