Research interests

cryptography,
1.1 specialized algorithms for computing with extremely long bit-length operands
1.2 Primality detection/decision (I have my own new method)

Spread Identity Internet Communications paradigm for robust DDoS defenses ;
as well as DDoS Offensive countermeasures in addition to substantially simpler network level trace-back to find the real location of attackers.

SMartER power grid: To leverage the power grid as a physically separate,
independent and remote-tamper-proof path to realize a provably correct location binding in any multi-factor authentication scheme.

anything and everything that happens to grab my attention. For example
(4.1) global warming (see my 2014 paper in the international sustainability conference)
(4.2) large scale sea water desalination architecture (U.S. patent issued in June 2024)
