Abstract
Cryptography plays a fundamental role in information security, being directly related to maintaining importantproperties such as confidentiality and integrity. Many of the algorithms that form the basis of cryptography are based onmathematically difficult computational problems, such as prime number factorization and discrete logarithm. However, theuse of quantum computing algorithms poses a threat to some of these cryptographic systems, making communicationsystems and protocols that use them vulnerable. One example is Delay-Tolerant Networks (DTNs), which have highapplicability in space systems and military contexts, but present challenging characteristics for secure implementation. Oneinitiative to combat this threat is the development of algorithms resistant to quantum attacks, collectively known as postquantumcryptography. These algorithms are based on other mathematical classes that do not have a known optimizedsolution for quantum or classical computers, but, on the other hand, present greater computational, storage, and datatransmission demands. Due to these characteristics, their use must be evaluated according to the context, considering thedegree of security required in conjunction with processing, memory, and routing limitations. Thus, this work aimed toconduct a survey of the main characteristics and challenges of cryptographic systems to counter quantum cryptanalysis,paying special attention to the post-quantum algorithm Module-Lattice Key-Encapsulation Mechanism (ML-KEM), as well asits vulnerabilities to hardware-level implementation attacks and spaceborne radiation environments. Furthermore, the mainarchitectural characteristics of DTNs were presented, and security aspects and challenges described in the Bundle ProtocolSecurity (BPSec)—specifically regarding the amplification of message-flooding vulnerabilities under expanded post-quantumpayloads—were addressed. Finally, suggestions for future work were presented based on opportunities identifiedthroughout the study.
