Abstract：With the development of quantum computing technology，Shor's algorithm poses a threat to the RSA cryptosystembasedonbigintegerfactorization.WhileLatice-based Cryptographypossessesquantumresistance，itsufersfrom issuessuchasagekeyszes，lowomputationaleencyandisufientcompaibilityiheistigpublicyifasture. To address his，thisstudy proposesaLatice-basedandRSAhybrideneryptionarchitecture withdynamic modulusupdating.It constructsakey exchange protocolbasedontheRing-Learning withErrors （RLWE）problemandacollaborativesecuritymodel fordynamic modulusRSA，enabling theintegrationof post-quantumsecurity mechanisms withtraditional encryptionsystems. Theoretical analysisshows thearchitectureis provablysecure under the IND-CPAsecuritymodel，with securityreduced to the hardness ofthe RLWE problem.Experimentsonthe Huawei Kunpeng 920 platform demonstrateakeygeneration efficencyof 3.8×104 ops/sec，a 2.1-fold improvement over CRYSTALS-Kyber.The encryption latency for IoT terminals is reduced to 45ms ，andit passes fullcompliance testing forNISTPQCRound 4.The studyprovidesatechnicalpathway balancing effciency andcompatibilityforquantum-securitymigration infieldslike5Gnetworksandfinancialinfrastructure，holdingsignificant theoretical and engineering value.
