Abstract:

Ensuring the security of cloud storage services is an ongoing challenge, due to the increasingly complex and dynamic threat landscape. One particular challenge is how to design security and efficient data encryption approaches. For example, the key used to encrypt data is generally a string of long random number, and this key is uploaded to the cloud server for security. The threshold password authentication secret sharing (TPASS) protocol is commonly used to save encryption keys. However, existing TPASS protocols may not fully achieve the desired security and efficiency levels due to the complexity of the protocol design. Hence, in this article, we propose an efficient dual-server secret sharing protocol (DssP) based on password authentication for cloud storage services. In our approach, users only need to remember a simple password to achieve random key access through dual server cooperation. We then mathematically prove that DssP meets the security requirements, and also evaluate its performance to show that it has less computational and communication overheads than other similar protocols.
