摘要: An Attribute-Based Signcryption (ABSC) is a natural extension of Encryption (ABE) and Signature (ABS), where we have the message confidentiality authenticity together. Since signer privacy captured in security ABS, it quite to expect that will also be preserved ABSC. In this paper, first propose an ABSC scheme which weak existential unforgeable, IND-CCA2 secure adaptive-predicates attack achieves privacy. Secondly, by applying strongly unforgeable one-time signature (OTS), above lifted attain strong unforgeability model. Both schemes are constructed on common setup, i.e public parameters key same for both encryption modules. Our construction flavor \(\mathcal{C}{t}\mathcal{E}\&\mathcal{S}\) paradigm, except one extra component computed using components ciphertext components. The second proposed follows new paradigm (extension \(\mathcal{C}{t}\mathcal{E}\&\mathcal{S}\)), call ”Commit then Encrypt Sign Sign” (\(\mathcal{C}{t}\mathcal{E}\&\mathcal{S}{t}\mathcal{S}\)). last done OTS scheme. non-repudiation achieved our systems achieve same.
