[. . . ] The XR150 is FIPS 140-2 Level 3 validated and features 256-bit AES hardware-based encryption using XTS block cipher mode. [. . . ] DataTraveler 6000 uses elliptic curve cryptography (ECC), which is recommended by the United States National Security Agency (NSA) as part of the NSA Suite B set of cryptographic algorithms. Encryption keys are protected with a 256-bit Master Key Encryption Key (MKEK), preserving the AES 256-bit encryption strength. Its 100% hardware authentication eliminates the possibility of password brute force attacks by destroying all critical security parameters , after 10 invalid login attempts. DataTraveler 6000 is rugged and waterproof 1 with a titanium-coated, stainless-steel casing for added durability. 4 Please note: Some of the listed capacity on a Flash storage device is used for formatting and other functions and thus is not available for data storage. As such, the actual available capacity for data storage is less than what is listed on the products.
