MLS-ABAC: Efficient multi-level security attribute-based access control scheme

• This paper proposes an outsourceable and lightweight multi-level secure attribute-based access control scheme
• Proposes an outsourceable and lightweight multi-level secure attribute-based access control scheme.
• We use the Ascon cryptosystem to further compress the ciphertext and replace the target group element with a shorter field element.
• We reduce the decryption cost by using an honest-but-curious intermediary Cloud based on the architecture.
• We combine dynamic and static attributes to grant data access, unlike prior works that only considered static attributes.
