Signcryption Scheme

Secure data transmission is a challenging issue in modern data communication. ID based generalized signcryption is a cost effective security primitive which provides authentication or confidentiality, or jointly confidentiality and authentication. Wei’s proposed an ID based generalized signcryption scheme for authentication and confidentiality of big data in a standard model, claiming that their scheme holds the security of indistinguishability against adaptive chosen-ciphertext attacks and existential unforgeability against adaptive chosen message attacks. In this paper, we analyzed Wei’s scheme by launching security attacks on the scheme to check its validity. As a result, it became clear and proved that the master secret key generated in the scheme is compromisable. Similarly, the mentioned scheme does not hold the security of indistinguishability against adaptive chosen-ciphertext attacks and existential unforgeability against adaptive chosen message attacks. Consequently, Wei’s schemes is prone to attacks and is insecure.

Data Volume

Big data transmission in wireless sensor network (WSN) consumes energy while the node in WSN is energy-limited, and the data transmitted needs to be encrypted resulting from the ease of being eavesdropped in WSN links. Compressive sensing (CS) can encrypt data and reduce the data volume to solve these two problems. However, the nodes in WSNs are not only energy-limited, but also storage and calculation resource-constrained. The traditional CS uses the measurement matrix as the secret key, which consumes a huge storage space. Moreover, the calculation cost of the traditional CS is large. In this paper, semitensor product compressive sensing (STP-CS) is proposed, which reduces the size of the secret key to save the storage space by breaking through the dimension match restriction of the matrix multiplication and decreases the calculation amount to save the calculation resource. Simulation results show that STP-CS encryption can achieve better performances of saving storage and calculation resources compared with the traditional CS encryption.

Signcryption Scheme

The mobile-health system, also known as the wireless body area network for remote patient monitoring, is a system used to remotely monitor the human body’s health status parameters in real time. The generalized signcryption can realize encryption, signature, and signcryption with only one key pair and one algorithm. To address the communication security requirement for the mobile-health system, Zhang et al. recently proposed a lightweight secure data transmission protocol for the mobile-health system, which uses a certificateless generalized signcryption scheme. However, Zhang et al.’s certificateless generalized signcryption scheme is insecure. In this article, we propose an improved certificateless generalized signcryption scheme and then give a rigorous security proof of it. The confidentiality of our improved scheme can be reduced to the computational Diffie–Hellman problem, and the unforgeability, the Elliptic Curve Discrete Logarithm problem. Performance evaluation shows that our scheme has only slightly increased computational and communicational costs compared with the original scheme, but it is more efficient than other certificateless generalized signcryption schemes existing at present. What is more, it is also an efficient scheme compared with those ones protecting the mobile-health system. Based on our scheme, the same lightweight secure data transmission protocol for the mobile-health system can also be constructed, just like the one based on the original scheme.
