文摘The rapid development of social technology has replaced physical interaction in the trading market.The implication of this technology is to provide access to the right information at the right time.The drawback of these technologies is that the eavesdropper can remove the user from the network and can create proxy participants.In this paper,we discuss how a social network overcome and prevent these data trading issues.To maintain the security of data trading,we applied ABE technique based on DBDH to secure data trading network.Our proposedτ-access policy scheme provides the best solution for the betterment of data trading network in terms of security.Inτ-access policy scheme,the users can encrypt and decrypt Private Transactions Information(PTI)using our proposedτ-access policy.The security properties ofτ-access policy are data confidentiality,data integrity,authenticity,non-repudiation,and unforgeability.The efficiency of our scheme is 77.73%,which is more suitable for data trading markets and trading strategies.
