提出了一个完全安全的基于身份的门限解密方案IB-ThDec,并将其安全性归结为四重判定双线性Diffie-Hellman问题,在随机预言机模型下给出了该方案的形式化安全性证明,同时证明了IB-ThDec可用于无证书公钥密码系统和基于身份的动态门限解密系统.
This paper proposes a fully secure identity-based threshold decryption scheme IB-ThDec and reduces its security to the quadruple Decision Bilinear Diffie-Hellman problem.The formal security proof of this scheme is provided in the random oracle model.Additionally,the(authors) show that IB-ThDec can be used to certificateless public key cryptosystem and the identity-based dynamic threshold decryption system.
