Security
Security options vary according to which McAfee Encrypted USB Device you are using.
In general, the two main areas of protection for each device include:
1. Access to the device—controlled by the authentication mechanisms available to
the device, including biometric (fingerprint), password, and two-factor. Two-factor
authentication requires both a biometric and a password to unlock a device.
2. Protection of private data—provided by encrypting the information belonging to
each user in private stores and partitions.
McAfee Encrypted USB Devices encrypt private partition data using the FIPS approved
AES algorithm (FIPS PUB 197). Data is automatically decrypted when the user opens
the file. All devices support the following AES key sizes: 128,192, and 256 bits.
However, the default key size for McAfee devices is 256-bit encryption, which is also the
only option available with Encrypted USB software. Other options are available through
the McAfee Software Development Kit. Encryption keys are unique to each user and are
generated each time you create a user.

The following list describes the requirements you need to use your device with
