Cryptography based Network Security Analysis using Secure Hashed Identity Message Authentication
Year: 2025
Type: article
Abstract: Network security in resource-constrained environments has become a critical challenge due to limited memory, power restrictions, and vulnerabilities to encryption attacks. Traditional approaches, such as Proxy Re-Encryption (PRE) and Lightweight Symmetric Asymmetric Encryption (LSAE), often sufferfrom computational overhead, latency, and inefficiency in real-timesystems. To address theseconcerns, this workproposesaSecureHashedIdentityMessageAuthentication (SHIMA) model that ensures data integrity, authentication, and efficient end-to-end encryption.Theproposed schemeintegrates SHIMAwithimprovedalgorithmssuchasAdvancedEncryption RSA (AERSA), Mono-alphabetic key substitution, and a modifiedCaesarcipher,therebyachievingenhancedsecurityand reduced latency. Simulation results demonstrate that SHIMA minimizes time complexity, improves packet delivery ratio, and increases throughput when compared to conventional schemes like PRE and LSAE. This framework provides a robust foundation for efficient, scalable, and secure communication across networked environments.
