Cryptographic consumer electronic devices filesystems performance

Wide usage of consumer electronic devices makes securing their data very important. Cryptographic file systems allow a consumer to encrypt and password protect removable drives, including USB drives, memory sticks, and flash cards. However wide usage of cryptographic file systems is limited due to their unknown performance. The wrong choice will leave users with a false sense of performance. This paper investigates the usage of the Linux Crypto APIs and demonstrates their performance in cryptographic file systems, most commonly used in CE, to help users decide which encryption algorithm should be used.
