摘要 针对泛在通信应用场景中数据传输的私密性要求,基于IBE公钥加密算法和Shamir门限秘密共享,提出了一种泛在通信隐私保护方案。方案以不同信任域身份标识为公钥,加密后的影子密钥可通过广播信道分发,满足门限条件的节点可以重构隐私会话密钥。方案具有随机预言模型下可证明的IND-sID-CPA安全性,支持安全的新成员加入策略,具有较小的计算复杂度和存储、通信开销。 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.
