Attribute-Based Data Retrieval with Keyword Search over Encrypted Data in Cloud

This paper presents searchable encryption with access control under multi-user setting with secure index represented by Hash Table structure encrypted by \( RC2 \) encryption algorithm and combine with Cipher-text Policy Attribute Based Encryption \( \left( {CP - ABE} \right) \). It can be efficiently constructed and implemented. Extensive analysis on selected data shows that proposed scheme is efficient and accurate.
