Secure and private key management scheme in big data networking
2018
Due to the penetration of various digital devices in our daily life, the data increases in an explosive way. It is highly agreed that the big data era is coming. Big data has a significant and promising future, and makes it a hot topic in the research community. Meanwhile, big data applications also raise consideration of security, privacy and trust on the networking layer. At present, the access control of cloud is vulnerable in existing schemes which may cause the loss and disclosure of the data easily. In this paper, we propose a secure key management scheme which may be deployed in big data networking to protect user’s data and privacy. In the proposed key management scheme, keys are divided into three layers. In the layered structure, upper keys encrypt lower keys to guarantee the security of keys. In the proposed scheme, big data networking, servers and others can know nothing of user’s key. Data owner can achieve ciphertext sharing to share their information to anyone they just went securely. Hierarchical key management is convenient, secure and efficient, and it can protect user’s private data in big data networking.
