Saeed Banaeian Far, Azadeh Imani Rad · IEEE Networking Letters · 2022
Blockchain technology has attracted many developers in various fields to launch their projects. DENT Wireless, a well-known telecom company, has developed the DENT project to provide blockchain-based eSIM and exchange. This exciting project has attracted many eSIM users. However, DENT cannot support data privacy if requested by the users. This letter offers a privacy-preserving framework based on the DENT project named PP-DENT striking a balance between users’ protection and regulatory policies. The PP-DENT enables privacy for eSIM users and conditional privacy for governments.
