Audio Encryption with AES and Blowfish
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 11
Abstract
With the rapid growth of information and communication industry, data transfer, communication of information, storing of data in cloud, sharing of valuable information across networks, raised the need of security of data. With the technological advancements data transfer is not confined only between computers/laptops they are now with the hand held devices like mobiles/tabs. So along with data security, speed and power consumption will also need attention. For secure communication over networks Cryptography is the proven tool. The rapid growth of digital data and its security raises the concern for developing more advanced techniques in cryptography. Cryptography is the physical process that scrambles the information by rearrangement and substitution of content, making it unreadable to anyone except the person capable of unscrambling it. Algorithms are there for different data types like text, image, audio, video etc. Throughputs, Speed, CPU time, Power Consumption and security are few parameters on which cryptographic algorithms are analyzed. The present paper analyses some common symmetric cryptographic algorithms like DES, 3DES, AES, and Blowfish on the above parameters. This paper provides a comparative analysis of the existing cryptographic techniques. Further an in-depth study of Blowfish algorithm and latest work done on it are also discussed.
