Descripción

This survey tackles a problem many IoT security papers gloss over: the birthday bound. When constrained devices run for years under a single long-lived key, single-call counter-mode designs quietly lose keystream security around 2^(n/2) regardless of key length. Beyond-birthday-bound constructions promise a way out, and the sum-of-permutations paradigm built on the NIST-standardized Ascon-p12 permutation offers an explicit advantage bound under one master key. But the research landscape is scattered. Theoretical proofs, quantum analysis, implementation hardening, side-channel and fault work, and AEAD composition each live in their own silo. This book pulls those threads together across five connected streams, from lightweight cryptography and its birthday-bound limits through BBB constructions, hardware implementation, implementation security, quantum resilience, and authenticated encryption composition. It maps where the evidence is strong and where it thins out, especially for constructions that combine single-master-key operation with domain-separated permutation calls. The result is a clear-eyed gap analysis and a practical recommendation: an integrated evaluation framework that treats cryptographic security, implementation efficiency, implementation hardening, quantum resilience, and AEAD composition as linked requirements rather than separate research problems. For researchers and engineers working on secure IoT deployment, this survey offers both a structured map of the field and a roadmap for the work still needed to make BBB stream ciphers genuinely deployment-ready.
