“…The disadvantage is that both of them need several rounds of interaction, which increases the delay and communication overhead. The threshold secret sharing based on low‐density parity‐check code (LDPC) is introduced into the key management to improve the efficiency of non‐reliable link networks in Zhou et al 22 In this scheme, even if part of the link is not reliable, the group key can be recomputed by any legitimate members. But it takes high communication cost.…”

Summary Space key management schemes play a critical role in space information network security services. However, the existing space key management schemes are inefficient. To overcome these problems, this paper proposed a cluster group key management scheme, in which the space nodes are divided into different clusters. The ground control center (GCC) is used as a private key generation center. The threshold technique based on low‐density parity‐check code (LDPC) is used in the group key management of the cluster‐heads. The key escrow is transferred to GCC, which is a compromise of efficiency and security. The logical key hierarchy is used to manage the group key of the cluster. Furthermore, the bilinear paring‐based cryptosystem is employed to provide the identification. The formalized security proof of the protocol using the Extended Canetti–Krawczyk (ECK) model is introduced to prove the authentication and security. The consistency, forward secrecy, backward secrecy, ability to against the collusion attack and performance are analyzed and simulated. The result shows that the proposed scheme takes lower storage cost and computational cost.

“…At the same time, lots of group key establishment protocols based on public key cryptography methods have been presented. However, most of these protocols [17][18][19][20][21] are the same as the above two protocols [15,16], only one key can be generated at a time for a single group.…”

Although nowadays lots of group key agreement schemes have been presented, most of these protocols generate a secret key for a single group. However, in the IoT HCS, more and more communications are involved in multiple groups and users can join multiple groups to communicate at the same time. Therefore, applying the conventional public-key-based one-at-a-time group key establishment protocols has heavy computational cost or suffer from security vulnerabilities. At the same time, in an IoT HCS, a trusted KGC is usually not available and so more flexible self-organized multigroup keys generation will be desired by all group members. In order to address this issue, a practical scheme for efficient and flexible KGC-free polynomial-based multigroup key establishments for IoT HCS is proposed. The proposed protocol can generate multiple group keys for all group members at once, instead of generating one key each time for a single group; more importantly, there is no need for a trusted KGC in the process of group keys establishment and each user can join multiple groups at the same time using only one reserved share. Meanwhile, the security of the proposed protocol is discussed in detail. Finally, we compare this protocol with the latest related group key distribution protocols in performance analysis. The results show that this efficient and flexible KGC-free polynomial-based multiple group keys establishment protocol is more suitable for practical group key agreement in IoT HCS.

In view of the shortcomings of the CCSDS-TC protocol key update mechanism, this paper proposes a satellite-ground key update scheme suitable for space communication. This article analyzes the encryption and authentication methods of the CCSDS-TC protocol, builds a satellite communication protocol simulation platform on OPNET, and implements the proposed satellite-ground key update scheme, encryption and authentication methods. The simulation test of the dynamic update of satellite-ground key and the simulation results of data security transmission denote that the proposed satellite-ground key update scheme in this paper has good security, scalability and low resource consumption, and can provide a secret key parameter which reveals important practical value.
