Identity based privacy preservation scheme for ubiquitous computing
Yang Zhen · Journal of Communications · 2011
Aiming at the privacy preservation of data transmission in ubiquitous computing,a privacy protected scheme based IBE cryptography and Shamir secret sharing was proposed.In the scheme,the public key was the ID of trusted field and the shares could be distributed during the broadcast channel.Any set of nodes satisfies the threshold can rebuilt the key of private session.The proposed scheme is IND-sID-CPA secure under random oracle model.Additionally,the scheme supports secure member expansion and has advantages in computation,storage and communication costs.
