Currently, with the threat of quantum computer attacks, the idea of combining several same-type primitives has reemerged. This is also the case for cryptographic keys where a hybrid quantum key exchange combination allows for preserving the security guarantees of pre-quantum schemes and achieving quantum resistance of post-quantum schemes. In this article, we present a concrete 3-key combiner system implemented on a Field Programmable Gate Arrays (FPGA) platform. Our system involves a pre-quantum Key EXchange scheme (KEX), a post-quantum key encapsulation mechanism, and a Quantum Key Distribution (QKD) algorithm. The proposed 3-key combiner is proven to be secure in the quantum standard model and it is INDistinguishable under a Chosen-Ciphertext Attack (IND-CCA). Our combiner can run in small FPGA platforms due to its relatively low resources usage. In particular, the key combiner without QKD is able to output up to 1 624 keys per second and the key combiner with QKD is able to output up to 9.2 keys per second.

“…Long-term Security: The de-facto standard countermeasure against emerging quantum computers is post-quantum cryptography. It provides strong formal security guarantees and can be coupled with "classic cryptography" to further enhance reliability and security [42]. Also, efficient, timing side-channel resistant implementations are available for practical applications [43].…”

This paper addresses one of the directions of the HORIZON EU CONVOLVE project being dependability of smart edge processors based on computation-in-memory and emerging memristor devices such as RRAM. It discusses how how this alternative computing paradigm will change the way we used to do manufacturing test. In addition, it describes how these emerging devices inherently suffering from many nonidealities are calling for new solutions in order to ensure accurate and reliable edge computing. Moreover, the paper also covers the security aspects for future edge processors and shows the challenges and the future directions.

“…The efficient construction of hybrid PQC-KEM combiners from weaker PKEs as a generalization of the Fujisaki-Okamoto (FO) transform was considered by Huguenin-Dumittan and Vaudenay [27]. A systematic mapping study for post-quantum hybrid key exchange was conducted by Giron et al [8].…”

“…Therefore, hybrid public-key schemes have become a focus of current research in the context of PQC, with particular emphasis on key-encapsulation mechanisms (KEMs) and digital signatures. The systematic mapping study of Giron et al [8] highlights the growing interest in hybrid PQC key-exchange. Note that the term "hybrid encryption" is more commonly used for the combination of KEMs and data encapsulation mechanisms (DEMs).…”

Using multiple, individual encryption schemes is a well-established method to increase the overall security of encrypted data. These so-called multiple encryption or hybrid schemes have regained traction in the context of public-key cryptography due to the rise of quantum computers, since it allows the combination of well-known classical encryption schemes with novel post-quantum schemes. In this paper, we conduct a survey of the state-of-the-art public-key multiple encryption (M-PKE) schemes. For the first time, we describe the most relevant M-PKE schemes in detail and discuss their security in a unified model, which allows better comparison between the schemes. Hence, we compare the security, efficiency, and complexity of the schemes and offer recommendations for usage based on common use cases. Our survey emphasizes the importance of being deliberate when combining encryption schemes, as small nuances can easily break security.
