Improvement Of Key Validation Efficiency In A Secure Mobile Messaging Application Using Sms-Based Public Key Cryptography (Sb-Pkc)

📄 Project Abstract

Short Message Service (SMS) is one of the most used mobile data services. It is utilized in wide range of applications including information delivery, remote operation of appliances, online purchases/banking transactions. However, some of these applications require that the underlying messaging protocol must guarantee secure communication; which traditional SMS cannot provide. State of the art approach to adding security to SMS messaging involves the use of asymmetric cryptography, supported by Public Key Infrastructure (PKI) for addressing public key verification/validation issues inherent in asymmetric-based cryptosystems. Despite PKI's good features, its key validation mechanism has potential for delay and high resource requirements; making it not appropriate for use in resource-constrained environments like mobile phones. Thus, this work aims to develop an asymmetric-based secure mobile messaging application (dubbed "ProSMS") with improved efficiency during key validation when comp...
