Zhong Shao · Information Security and Communications Privacy · 2009
In real life, existing thus situation, one belongs to a group with some attributes wants to upload sensitive data with his signature to a third-party website, and wants the data can be shared by one belongs to the group possessing specific attributes. To satisfy these needs, we defined an Attribute-based signcryption scheme. In our scheme, the ciphertexts are labeled with sets of attributes, the private keys are associated with access structures that control which texts a user is able to sign or decrypt. Finally, we give the correctness and security analysis of the scheme.
