is the founder of information theory and studies the mathematical theory of information measurement, channel capacity and security systems.
Biographical or institutional source material ↗’s relevance in technology cases
The following cases cite their theories, methods or industry contributions; the historical basis does not mean that I directly participated in or invented modern products alone.
Starlink low orbit satellite communication system Interdisciplinary principle illustration of ↗
constellation coverage and ground visible arc affect connection opportunities, and link budget is affected by distance, antenna gain, bandwidth and noise; secure communication also requires key management and protocol guarantees. Concept screening of
Illumina NovaSeq X Sequencing System ↗
sequencing reads need to undergo quality assessment, comparison and statistical analysis; coverage depth, error probability and sample bias jointly affect the variation evidence, and the number of original bases is not equivalent to the amount of effective information.
Oxford Nanopore PromethION ↗
molecules cause current changes through the pores, and the algorithm interprets the time signal as a sequence; read length, error characteristics, modification identification and sample processing are interrelated.
Yubico YubiKey 5 Security Key ↗
public key authentication combines device possession with protocol challenge response, and security also relies on registration, recovery, user operation and server verification processes.
IBM Crypto Express cryptographic hardware ↗
high-throughput cryptographic operations and security key isolation require the collaboration of hardware, firmware, and access control; side-channel protection and operation and maintenance processes cannot be guaranteed by algorithm correctness alone.
