A Review of Research on Dual -Server Public-Key Encryption with Keyword Search for Secure Cloud Storage

Computer Engineering

Now a day’s there will be growing popularity of cloud computing, large number of users and data owners are motivated to outsource their data to cloud servers for large convenience and reduced cost required for data management. However, important data should be encrypted before outsourcing for privacy requirements, which uses data utilisation technique like keyword-based document retrieval. Searchable encryption is of expanding enthusiasm for ensuring the information protection in secure searchable distributed storage. In this paper, we research the security of a notable cryptographic primitive, in particular, public key encryption with keyword search (PEKS) which is exceptionally valuable in numerous utilizations of cloud storage. The conventional PEKS structure experiences an inalienable instability called inside Brut force keyword guessing attack propelled by the pernicious server. To address this security defencelessness, we propose another PEKS system named double server PEKS (DS-PEKS). As another principle commitment, we characterise another variation of the smooth projective hash capacities (SPHFs) alluded to as direct and homomorphic SPHF (LH-SPHF). We then demonstrate a bland development of secure DS-PEKS from LH-SPHF. To outline the plausibility of our new structure, we proposed system which makes system easy to handle and effective mechanism to handle complex task with better result with dual server public key encryption of the proposed scheme.
