Public Key Encryption for Keyword Search in Cloud Using Kdm Security Scheme

Abstract

Searchable encryption is of growing interest for protective the records privateness in secure searchable cloud storage. In this paper, we study the safety of a famous cryptographic primitive, in particular, public key encryption with key-word search (PEKS) which could be very useful in lots of applications of cloud garage. To address this safety vulnerability, we recommend a today's PEKS framework named dual-server PEKS (DS-PEKS).We present new frameworks for constructing public-key encryption schemes satisfying key-set up message (KDM) protection. We present new frameworks for building KDM-relaxed encryption schemes and twin mode cryptosystems that admit a very easy and modular assessment.
