Assured Sensitive Data Sharing on a Big Data Platform using Proxy Re-Encryption (PRE) Algorithm

Users store vast amounts of sensitive data on a big data platform. Sharing sensitive data will help enterprises reduce the cost of providing users with personalized services and provide value-added data services. However, secure data sharing is problematic. This paper proposes a framework for secure sensitive data sharing on a big data platform, including secure data delivery, storage, big data sharing platform. We present a proxy re-encryption algorithm based on heterogeneous cipher text transformation The framework protects the security of users’ sensitive data effectively and shares these data safely.
