“…Security is a critical concern faced by satellite communications [5] since the wireless information intended for the destination devices are also obtained by the non-intended third parties (i.e., eavesdroppers (Eves)) in the same beam due to the openness of wireless links. In order to provide a high level of information security, appropriate signal processing and communication technologies need to be invoked to guarantee the secure communication and the link qualities.…”

Abstract-Cognitive satellite-terrestrial networks (CSTNs) have been recognized as a promising network architecture for addressing spectrum scarcity problem in next-generation communication networks. In this paper, we investigate the secure transmission for CSTNs where the terrestrial base station (BS) serving as a green interference resource is introduced to enhance the security of the satellite link. Adopting a stochastic model for the channel state information (CSI) uncertainty, we propose a secure and robust beamforming framework to minimize the transmit power, while satisfying a range of outage (probabilistic) constraints concerning the signal-to-interference-plus-noise ratio (SINR) recorded at the satellite user and the terrestrial user, the leakage-SINR recorded at the eavesdropper, as well as the interference power recorded at the satellite user. The resulting robust optimization problem is highly intractable and the key observation is that the highly intractable probability constraints can be equivalently reformulated as the deterministic versions with Gaussian statistics. In this regard, we develop two robust reformulation methods, namely S-Procedure and Bernstein-type inequality restriction techniques, to obtain a safe approximate solution. In the meantime, the computational complexities of the proposed schemes are analyzed. Finally, the effectiveness of the proposed schemes are demonstrated by numerical results with different system parameters.

“…Several security architectures have been proposed for satellites to remotely manage their hardware configuration from the ground station [16], and for purposes of key distribution [17] and management [18], [19], [20]. All of those works make use of cryptographic primitives such as hash functions to achieve their goals, but none of them considers the harsh environment surrounding spacecrafts and more specifically the resistance to SEUs.…”

Abstract-Satellites are extensively used by public and private sectors to support a variety of services. Considering the cost and the strategic importance of these spacecrafts, it is fundamental to utilize strong cryptographic primitives to assure their security. However, it is of utmost importance to consider fault tolerance in their designs due to the harsh environment found in space, while keeping low area and power consumption. Therefore, this paper proposes novel fault tolerant schemes for the SHA-2 family of hash functions and analyzes their resistance to SEUs. Results obtained through FPGA implementation show that our best fault tolerant scheme for SHA-512 uses up to 32% less area and consumes up to 43% less power than the commonly used TMR technique. Moreover, its memory and registers are 435 and 175 times more resistant to SEUs than TMR. These results are crucial for supporting low area and low power fault tolerant cryptographic primitives in satellites.

“…Researchers have suggested using IPsec with multiple keys [10,11,31,32] or with more data in the clear [1,12] to support services on devices that are not at the endpoints of communication. The focus of those publications, and derivative works [20,21], was largely to improve performance of flows, not to increase the security of the system. When security is discussed, it is usually in the context of packet-filtering firewalls.…”

Making Network Intrusion Detection Work With IPsec

Network-based intrusion detection systems (NIDSs) are one component of a comprehensive network security solution. The use of IPsec, which encrypts network traffic, renders network intrusion detection virtually useless unless traffic is decrypted at network gateways. One alternative to NIDSs, host-based intrusion detection systems (HIDSs), provides some of the functionality of NIDSs but with limitations. HIDSs cannot perform a network-wide analysis and can be subverted if a host is compromised. We propose an approach to intrusion detection that coinbines HIDS, NIDS, and a version of IPsec that encrypts the header and the body of IP packets separately. We refer to the latter generically as Two-Key IPsec. We show that all of the network events currently detectable by the Snort NIDS on unencrypted network traffic are also detectable on encrypted network traffic using this approach. The NIDS detects network-level events that HIDSs have trouble detecting and HIDSs detect application-level events that can't be detected by the NIDS. 111 ACKNOWLEDGMENTSThis work was sponsored by David Kenyon of the Air Force Electronic Systems Command, GIG Network Architecture Office.
