Email Plugin Suite for k-Resilient Identity-Based Encryption and Searchable Encryption
Kah-Wai Chew, Swee‐Huay Heng · 2022
Nowadays, most of the companies use their preferred email platform to perform their daily tasks such as exchanging of messages and sharing of documents.However, it is quite often to hear the news that someone's email account is being hacked.The malicious intention of the hackers is to hijack the users' personal information or company documents.Thus, cryptography plays an important role to provide more a secure email platform.Identity-based encryption (IBE) is a public key cryptosystem that uses a unique identifier such as email address or IP address to generate the user public key and it relies on a trusted third party to generate the corresponding user private key.As compared to conventional public key infrastructure, users now no longer need to distribute their public keys to others.Meanwhile, searching over encrypted emails could be a challenging task.In order to overcome this, the concept of public key encryption with keyword search (PEKS) was introduced to enable searching for the encrypted keywords without revealing anything about the original email.This research focuses on implementing and integrating both IBE and PEKS with encryption and searching functionalities into an email platform via an email plugin.More precisely, this project is to design an email plugin suite using k-resilient identity-based encryption and k-resilient searchable encryption in order to provide a more secure email platform.The performance analysis shows promising result.
