A Comparative Study of Homomorphic and Searchable Encryption Schemes for Cloud Computing
This work provides a comparative analysis for researchers and practitioners in cloud security, but it is incremental as it reviews existing methods without introducing new solutions.
The paper conducted a comparative study of searchable and homomorphic encryption methods to address data confidentiality and privacy issues in cloud computing, presenting an analysis of these cryptographic techniques.
Cloud computing is a popular distributed network and utility model based technology. Since in cloud the data is outsourced to third parties, the protection of confidentiality and privacy of user data becomes important. Different methods for securing the data in cloud have been proposed by researchers including but not limited to Oblivious RAM, Searchable Encryption, Functional Encryption, Homomorphic Encryption etc. This paper focuses on Searchable and Homomorphic Encryption methods. Finally, a comparative study of these two efficient cloud cryptographic methods has been carried out and given here.
