The scheme we propose is a very exible encryption and authentication primitive. We build this scheme on two relatively new design principles: t-functions and fast pseudo hadamard transforms. We recapitulate the theory behind these principles and analyze their security properties and efficiency. In more detail we propose a streamcipher which outputs a message authentication tag along with theencrypted data stream with only little overhead. Moreover we proposesecurity-speed tradeoffs. Our scheme is faster than other comparablet-function based designs while offering the same security level. }, journal = {International Journal of Computer and Information Engineering}, volume = {1}, number = {5}, year = {2007}, pages = {1267 - 1272}, ee = {https://publications.waset.org/pdf/13472}, url = {https://publications.waset.org/vol/5}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 5, 2007}, }
