A ciphertext-policy attribute-based encryption scheme with optimized ciphertext size and fast decryption
( Association for Computing Machinery, Inc , 2017 , Conference Paper)We address the problem of ciphertext-policy attribute-based encryption with fine access control, a cryptographic primitive which has many concrete application scenarios such as Pay-TV, e-Health, Cloud Storage and so on. ... -
Decentralized broadcast encryption schemes with constant size ciphertext and fast decryption
( MDPI AG , 2020 , Article)Broadcast encryption (BE) allows a sender to encrypt a message to an arbitrary target set of legitimate users and to prevent non-legitimate users from recovering the broadcast information. BE has numerous practical ... -
Decentralized ciphertext-policy attribute-based encryption schemes for lightweight devices
( Elsevier B.V. , 2019 , Article)In a traditional attribute-based encryption (ABE) system, there is only one central authority who generates and hence knows the secret keys of all users, this problem is known as the key escrow problem. An ABE scheme which ...
