摘要 多身份单密钥解密方案是基于身份加密方案的一个变体,用户的一个解密密钥可以对应于多个公钥(身份),即单一的密钥可以解密多个不同公钥加密下的密文。在双线性对,提出标准模型下可证安全的多身份单密钥解密方案。在判定性q-TBDHE假设下,证明了所提方案在适应性选择密文和身份攻击下是不可区分的。 Multi Identity SinglcKcy Decryption （ MISKD） scheme is a variant of Identity-Based Encryption（IBE） where a private decryption key can map multiple public keys （identities）. More to decrypt multiple ciphertexts encrypted with different public keys. Based on exactly, a single private key can be used the bilinear pairings, the MISKI）scheme was presented and was provably secure in the standard model. The proposed scheme was proven secure against indistinguishably in adaptively chosen ciphertext and identity under the decision q-TBDHE assumption.
