Selective encryption can protect the most important content in wireless streaming video without running down batteries on mobile devices, according to a university researcher.
Small wireless circuit boards need selective encryption to protect streaming video without running mobile batteries down, according to South Dakota State University scientist Wei Wang.
Today users must choose between using unsecured wireless transmissions and running down their battery with encryption algorithms just to prevent eavesdropping on video streams. The selective encryption approach could cut battery usage, said Wei Wang, an engineering professor at South Dakota State University in Brookings who headed the five-university research team that investigated the technique.
