A secure and efficient Ciphertext-Policy Attribute-Based Signcryption for Personal Health Records sharing in cloud computing
TL;DR: A provable secure CP-ABSC scheme for cloud-based PHR sharing system that has ability to provide fine-grained access control, confidentiality, authenticity, signcryptor privacy and public verifiability, simultaneously is proposed.
Journal ArticleDOI
Pairing-based CP-ABE with constant-size ciphertexts and secret keys for cloud environment
Vanga Odelu,Ashok Kumar Das,Y. Sreenivasa Rao,Saru Kumari,Muhammad Khurram Khan,Kim-Kwang Raymond Choo +5 more
TL;DR: A new pairing-based CP-ABE scheme, which offers both constant size ciphertexts and secret keys (CSCTSK) with an expressive AND gate access structure and is secure against chosen-ciphertext adversary in the selective security model is proposed.
Journal ArticleDOI
Efficient attribute-based signature and signcryption realizing expressive access structures
Y. Sreenivasa Rao,Ratna Dutta +1 more
TL;DR: This paper designs two key-policy ABS schemes with constant-size signature for expressive linear secret-sharing scheme (LSSS)-realizable monotone access structures and proposes a new attribute-based signcryption scheme for LSSS-realizable access structures utilizing only 6 pairings and making the ciphertext size constant.
Book ChapterDOI
Expressive Bandwidth-Efficient Attribute Based Signature and Signcryption in Standard Model
Y. Sreenivasa Rao,Ratna Dutta +1 more
TL;DR: An efficient key-policy attribute based signature (ABS) scheme with constant-size signature for expressive linear secret-sharing scheme (LSSS)-realizable monotone access structures with only 3 pairings for the verification algorithm, which is an affirmative answer for one of the open problems left in Pairing 2012.
Book ChapterDOI
Recipient Anonymous Ciphertext-Policy Attribute Based Encryption
Y. Sreenivasa Rao,Ratna Dutta +1 more
TL;DR: To the best of the knowledge, this is the first fully secure CP-ABE scheme with hidden access policy as well as constant ciphertext length which preserves recipient anonymity.
