Transforming Attribute-Based Encryption schemes into Asymmetric Searchable Encryption schemes

Attribute-Based Encryption (ABE) and Asymmetric Searchable Encryption (ASE) are two highly useful Public-Key Encryption (PKE) technologies in today's cloud computing landscape.By leveraging the idea that the attributes from ABE can serve as keywords for ASE, we propose an efficient technique to translate any ABE schemes into ASE schemes.We address both the case of Ciphertext-Policy Attribute-Based Searchable Encryption (CP-ABSE) and Key-Policy Attribute-Based Searchable Encryption (KP-ABSE) schemes.Our main goal with these schemes is to maintain the security properties of ABE while introducing efficient search capabilities, thereby facilitating further advancements in ASE development.To validate our theoretical proposals, we have analyzed their practical applicability using existing ABE implementations.
