Chosen Ciphertext Secure Identity-based Encryption in the Standard Model
标准模型下选择密文安全的基于身份加密方案

In Eurocrypt 2005,Waters' identity-based encryption scheme suffers from a drawback that the scheme only guarantees chosen plaintext security,which hampers its applications in higher security level environments.A chosen ciphertext secure identity-based encryption scheme was proposed to remedy this drawback.The proposed encryption scheme was regarded as the extended version of Waters' scheme with only one additional element in the ciphertext,and guaranteed chosen ciphertext security.The extended scheme's indi...
