Abstract
Consumer electronics (CE) products are showing strong growth in usage and purchase intent. Consumers are driving a revolution in the way they access, store, and use digital content. With constant upgrade cycles and data capacity increases, securing personal data becomes a more important problem every day. Cryptographic file systems allow a consumer to encrypt and password-protect removable drives, including universal serial bus (USB) drives, memory sticks, and flash cards. Linux and open source provide different solutions for this matter. Linux is a popular choice for application developers of today's the Internet of Things (IoT)and wireless consumer devices because of its flexibility and ease of use. However, wide usage of cryptographic file systems is limited due to its lack of standardization. The wrong choice of API could leave users with a false sense of performance, or worse, with a false sense of security. This paper performs a comprehensive comparison of cipher algorithms and investigates the usage of the Linux Cryptoloop and Dm-crypt Crypto application programming interfaces (APIs) and demonstrates their performance in cryptographic file systems most commonly used in CE, to help users decide which encryption method and algorithm should be used.
