“…The pre-stored r is selected from the database of GS and corrected by ECC, u. Finally, the key between the Terminal and GS is extracted by Privacy Amplification [49,50,52]. The related response, r , can be used only once to avoid a replay attack.…”

“…The terminal selects a challenge, 𝑐, and the SSL outputs the response, 𝑟. The BCH (Bose, Ray-Chaudhuri, and Hocquenghem) code is used as an IR procedure, which is efficient for error correcting code [50,52]. The Error Correcting Code (ECC), 𝑢, is sent to GS instead of the response, 𝑟, which has redundant information of r. The challenge, 𝑐, is sent to GS through the public channel too.…”

“…Compared to the regular SSL PUF, the key distribution scheme is simple and clear for matched SSL pairs, as shown in Figure 4. A SSL PUF chip, ssl i , matched to ssl i is installed in GS that has a similar response with the satellite, Sat ssl i , inspired by the same seed [49,52]. The KeyGen procedure generates helper data publicly sent together with the seed to associate the Key Recover procedure.…”

“…The challenge, c, response, r, error correcting code, u, and Hel per data are 511 bits because the SSL PUF chip has a 5% deviation for the same challenge. BCH and Privacy Amplification modules are used to correct the deviation, and full entropy is ensured by the min-entropy of SSL [52]. The communication overhead of the terminal authentication protocol is in Table 6.…”

The Space–Air–Ground Integrated Network (SAGIN) expands cyberspace greatly. Dynamic network architecture, complex communication links, limited resources, and diverse environments make SAGIN’s authentication and key distribution much more difficult. Public key cryptography is a better choice for terminals to access SAGIN dynamically, but it is time-consuming. The semiconductor superlattice (SSL) is a strong Physical Unclonable Function (PUF) to be the hardware root of security, and the matched SSL pairs can achieve full entropy key distribution through an insecure public channel. Thus, an access authentication and key distribution scheme is proposed. The inherent security of SSL makes the authentication and key distribution spontaneously achieved without a key management burden and solves the assumption that excellent performance is based on pre-shared symmetric keys. The proposed scheme achieves the intended authentication, confidentiality, integrity, and forward security, which can defend against masquerade attacks, replay attacks, and man-in-the-middle attacks. The formal security analysis substantiates the security goal. The performance evaluation results confirm that the proposed protocols have an obvious advantage over the elliptic curve or bilinear pairings-based protocols. Compared with the protocols based on the pre-distributed symmetric key, our scheme shows unconditional security and dynamic key management with the same level performance.

“…Then, we use mature channel error correction technology to correct the inconsistent data bits between the two communication terminals, thereby obtaining the secure key. We need to use an error correction code near Shannon channel capacity, usually the low-density parity-check (LDPC) code [2,13,14], to realize efficient reconciliation. However, under the condition of extremely low signal-to-noise ratio (SNR), better error correction performance is usually accompanied by higher algorithm complexity.…”

High-speed reconciliation is indispensable for supporting the continuous-variable quantum key distribution (CV-QKD) system to generate the secure key in real-time. However, the error correction process’s high complexity and low processing speed limit the reconciliation speed. Therefore, reconciliation has also become the bottleneck of system performance. In this paper, we proposed a high-speed reconciliation scheme that uses the deep neural network to optimize the decoding process of the low-density parity-check (LDPC) code. We first introduced a network structure of decoding implementation based on the deep neural network, which can be applied to decoding algorithms of parallel strategy and significantly reduce the decoding complexity. Subsequently, we proposed two improved decoding algorithms based on this structure, named linear fitting algorithm and deep neural network-assisted decoding algorithm. Finally, we introduced a high-speed reconciliation scheme based on the CPU-GPU hybrid platform. Simulation results show that the proposed reconciliation scheme reduces the complexity and enables us to realize the high-speed CV-QKD system. Furthermore, the improved decoding algorithm can also reduce the FER, thereby increasing the secret key rate.
