Enhancing the security of user data using the keyword encryption and hybrid cryptographic algorithm in cloud

摘要

Cloud computing is a popular model for accessing the computer resources. The data owner outsources their data on cloud server that can be accessed by an authorized user. In Cloud Computing public key encryption with equality test (PKEET) provides an alternative to public key encryption by simplify the public key and credential administration at Public Key Infrastructure (PKI). However it still faces the security risk in outsourced computation on encrypted data. Therefore this paper proposed a novel identity based hybrid encryption (RSA with ECC) to enhance the security of outsourced data. In this approach sender encrypts the sensitive data using hybrid algorithm. Then the proxy re encryption is used to encrypt the keyword and identity in standardize toward enrichment security of data.
