SURVEY ON SECURE DATA EXCHANGE USING AUTHENTICATED CIPHERTEXT-POLICY ATTRIBUTED-BASED ENCRYPTION

Abstract In a day to day life, security plays a vital role to protect and authenticate our data from various introducers. This paper focuses on Secure Data Exchange using Authenticated Cipher text-Policy Attributed-Based Encryption.Security is major issue on data sharing system. Different Encryption technologies are used for providing security . Here, ciphertext attribute based encryption along with HMAC process were used. This integrated an authentication and confidentiality feature simultaneously for providing secure data. Keyword: Authentication, HMAC, MAC, Encryption.
