Cruzer Enterprise
Product Specifications
Revision 1.0
1. Scope
This Product Specification document provides product and technical information for the Cruzer Enterprise
using the S2 controller. This document is intended for System and IT Administrators who are responsible for
the care and maintenance of the Cruzer Enterprise.
2. Product Overview
Cruzer Enterprise offers the following features:
•
•
•
Cruzer Enterprise is 2.0 High Speed compliant and 1.1 Full Speed compatible
The drive is fully secured using a sophisticated password mechanism
Cruzer Enterprise includes a 256-bit AES hardware-based encryption
Cruzer Enterprise can be managed using Cruzer Enterprise CMC, a software based interface that provides
corporate networks with security against internal threats and loss of corporate sensitive data, while securing
data residing on corporate issued Cruzer Enterprise drives.
As with any USB Flash drive, the Cruzer Enterprise drive can be used to store data. However, all
information on the Cruzer Enterprise is securely stored and encrypted with a 256-bit AES hardware based
encryption. It is also secured using a sophisticated password protection method. In addition, the Cruzer
Enterprise includes a “lockdown” mode for enhanced security. This lockdown feature will lock the Cruzer
Enterprise whenever a maximum number of password attempts exceed a pre-configured value. In the event
that the device is locked, the device must be reformatted to enable operation. All data on the Cruzer
Enterprise will be erased.
2.1 Product Architecture
The Cruzer Enterprise is based on the SanDisk S2 controller, which is designed for data storage applications.
It combines these storage capabilities with a self-contained system based on the ARM7-TDMI 32-bit RISC
processor to enable a wide range of applications. Users can extend device functionality with applications
based on the S2 platform to secure files, personalize the user interface, and other functions.
The following diagram illustrates the main functional blocks of the S2 controller:

2.2 Data Security
The Cruzer Enterprise security architecture combines hardware-based access control and security features
that are insulated from the host computer environment.
Cruzer Enterprise implements a double security mechanism, access control and data encryption, based on
SHA-1 and AES algorithms. Encrypted data is stored in a secure zone, hidden until successful authentication
is completed by the Cruzer Enterprise access control mechanism. This method of encryption and
authentication is more secure than software commands. Data is encrypted and decrypted dynamically within
the device, thus only data required by the host PC is decrypted and sent to the PC.
2.2.1
Access Control - Maximum Number of Attempts (Max
NOA)
Cruzer Enterprise locks automatically for further access after a predefined number of consecutive, incorrect
password attempts. This number is defined during the manufacturing process. This feature prevents brute
force attacks, where the hacker tries several password variations in order to determine the correct password.
2.2.2
Encryption Algorithms
Cruzer Enterprise implements industry-standard symmetric and asymmetric algorithms. No proprietary
algorithms are used.
Symmetric Algorithm
Cruzer Enterprise supports the symmetric AES algorithm described in Table 1.
The Parallel AES Coprocessor is used for fast computation of the Advanced Encryption Standard algorithm.
The AES algorithm is described by the FIPS PUB 197 Advanced Encryption Standard.

Figure 2 illustrates the encryption flow using the Electronic Code Book (ECB) encryption mode. Details of
the encryption and decryption cycles follow.
Figure 2: TDEA Electronic Code Book (TECB) Mode
In TECB encryption, a 256-bit plaintext data block (P) is used directly as the input block (I). The input block
is processed through the AES encoder using a 256-bit key. The resulting 256-bit output block (O) is used
directly as ciphertext (C).

Revision 1.0
In TECB decryption, a 256-bit ciphertext block (C) is used directly as the input block (I). The input block is
processed through the AES decoder using the same 256-bit key. The resulting 256-bit output block (O)
produces the plaintext (P).
Hashing Algorithm
Cruzer Enterprise implements a SHA-1 hash function as part of access control and creation of a symmetric
encryption key for flash data.
Random Number Generator
Cruzer Enterprise implements a hardware Random Number Generator.
2.3 System Requirements
The system requirements for the Cruzer Enterprise are as follows:
•
•
