“…Since the group scale and dynamics highly influence the network overhead, the proposed scheme exploits a logical key hierarchy (LKH) to reduce the life-cycle key management costs. For the marine-based STIN scenario, Shen et al in [24] design a secure emergency data protection scheme. Specifically, the proposed scheme exploits a block-design-based key agreement to achieve efficient communication among the satellites.…”

Ubiquitous connection to modern vehicles is mandatory to support diverse intelligent functions, including autonomous driving, telediagnosis, infotainment services, and others. Since the deployment of the cellular access points is still scarce in rural areas, the low earth orbit (LEO) constellationbased communication is believed to provide a realistic alternative. However, due to the long propagation delay and limited satellite on-board processing ability, the design of security protocols in LEO constellations remain challenging. Aiming at these challenges, we propose a secure user access and inter-satellite handover mechanism, which achieves the control-and userplane key separation. Specifically, our proposed scheme exploits an identity-based encryption scheme with proxy re-encryption to achieve the key establishments with high efficiency, and it also achieves the highly efficient secure batch handover with the assistance of a stack. Detailed analysis is performed to demonstrate the security properties of our proposed scheme, in terms of confidentiality, authentication, and forward/backward key separation. Furthermore, simulation results illustrate that our proposed scheme achieves high computational complexity and communication overheads in comparison with a traditional scheme.

“…In general, encryption algorithms can be divided into asymmetric encryption and symmetric encryption algorithms. Shen et al [109] used the asymmetric encryption algorithm to realize a secure transmission of messages. This algorithm encrypts the address and payload using different keys, and satellite nodes can only obtain address information.…”

Space Information Network (SIN) is a multi-purpose heterogeneous network. Due to the large-scale of SIN, its secure and stable operation is vulnerable to various threats. Much of current threat analysis for SIN is based on the network function or architecture. However, this approach cannot clearly divide the relation between threats and secure communication measures for a highly integrated network. Furthermore, it will lead to overlapping in segregation of secure duties. This paper presents a comprehensive review of threats and corresponding solutions in SIN from the perspective of network security attributes. In order to make the analysis applicable to more scenarios, the following three most essential attributes, confidentiality, integrity and availability, are selected as the threatened objectives. At the same time, for cross-reference with the analysis based on network function or architecture, this paper relates network layers to network security attributes through secure communication mechanisms. Specifically, the confidentiality includes confidential information-exchange and Authentication and Key Agreement (AKA), the integrity includes information identification and information restoration, and the availability includes link establishment, routing mechanism, and mobility management. According to above framework, this paper provides a cross-layer perspective for analyzing threat and enhancing the security and stability of SIN. Finally, this paper concludes with a summary of challenges and future work in SIN.

“…In the ECC cryptography system [6], the elliptic curve equation is defined as E p (a, b): y 2 = x 3 + ax + b (mod p) over F p , where b ∈ F p , p > 3 and 4a 3 + 27b 2 (mod p) is not equal to 0. In general, the security of ECC depends on the following difficult problems [22][23][24][25][26].…”

Internet of things (IoT) is used to provide real-time data collection and analysis of the target area by the cooperation of low-cost devices. The authentication towards multiple devices has become the research hot-spot considering of the requirement in real applications. Sensitivity and privacy of data have caused widespread concerns because low-cost devices are neither tamper-proof nor capable of performing public key cryptography efficiently. However, many researchers only focus on the authentication between two devices in the network. They ignore the authentication among group devices attached to one network. In this paper, we propose A Practical Group Authentication Scheme for Smart Devices in IoT. Note that one device group to be authenticated consists of a group of smart devices. The personal digital assistant (PDA) as the group leader controls authentication operations in its group. From the security analysis, our scheme can resist to various attacks. In addition, the performance analysis shows that our scheme has lower computational cost than the existing scheme.
