1、QUANTUM-SAFE CRYPTOGRAPHY IN MANAGED FILE TRANSFER(MFT):WITH MICROSOFT QUANTUM UPDATESECURING DATA IN THE QUANTUM ERA PRESENTED BY DAVID HEATH-HTTPS:/WWW.YOUTUBE.COM/WATCH?V=1_GJP2UAJO0INTRODUCTIONQuantum cryptography secures Managed File Transfer(MFT)against quantum threats.Microsofts February 2025

2、 breakthrough suggests quantum computers could break encryption in 5-10 years.As of August 24,2024 NIST is encouraging computer system administrators to begin transitioning to the new standards as soon as possible.Presidential order went from 2035 to as soon as possible.Immediate updates to MFT syst

3、ems are critical.PQC e.g.,Kyber public and private keysDilithium Digital Signatures:Quantum-resistant algorithms for existing systems.WHAT IS MANAGED FILE TRANSFER(MFT)?MFT securely moves files between locations(e.g.,corporate branches,partners).Uses RSA for key exchange and AES for encryption.Vulne

4、rable to quantum computers via Shors algorithm(breaks RSA)Why current methods need updating?THE QUANTUM THREATShors algorithm:Breaks RSA by factoring large numbers quickly.Grovers algorithm:Halves AES key strength,making brute-force easier.Risk:Data harvested now could be decrypted laterThe looming

5、quantum computing risk.HOW QUANTUM CRYPTOGRAPHY HELPSQuantum Key Distribution(QKD):Uses quantum mechanics for secure key sharing.Detects eavesdropping via the observer effect.Secures MFT by replacing vulnerable key exchanges with QKD keys for AES.QKDs unbreakable security.-MICROSOFTS QUANTUM BREAKTH

6、ROUGHFebruary 19,2025:Microsoft creates topological qubits using new matter(topological superconductors).-ForbesGoal:Million-qubit computers in years,not decades.Implication:RSA could be broken in 5-10 yearsQKD IN MFT:HOW IT WORKS-Steps:1.Establish quantum channel(fiber-optic or free-space).2.Use QK
