An Efficient Revocable Attribute-Based Signcryption Scheme with Outsourced Unsigncryption in Cloud Computing
2019
IEEE Access
In this paper, we present an efficient revocable signcryption (CP-ABSC) with outsourced unsigncryption scheme based on ciphertext-policy attribute based encryption (CP-ABE) to secure the data sharing in cloud computing that require access control, data encryption, and authentication to ensure message integrity and confidentiality. It can be used to signcrypt a message based on the access rights specified by the message itself. A user can decrypt a ciphertext if and only if it possesses the
