Public Key Infrastructure (PKI) based or Identity-based Encryption (IBE) based authentication schemes are introduced into network storage systems recently. However, the schemes have unavoidable disadvantages:(1)the exchange of digital certificates are complicated.(2)the public key is long.(3)the transmission of private key is vulnerable. In this paper, we design a network storage authentication scheme using Double-PKG. The theoretical and experimental results show that it can ensure the confidentiality, integrity, availability and non-repudiation during data transmission and storage. Our scheme uses the double authentication infrastructure. And it can effectively protect the key transmission. The data encryption and decryption in experiments are relatively stable, so the overall scheme efficiency has been greatly improved.
