1-Wire Software Authorization SDK

The 1-Wire^® Software Authorization Kit is a software development kit (SDK) designed specifically to help secure software programs and to provide license control and user validation services. The SDK contains a software authorization library built on top of the popular 1-Wire Public Domain Kit's software libraries and provides a complete application programming interface (API). The software authorization library can be integrated into the application developer's custom software, and then distributed with it. The library provides authentication services that communicate to an iButton^® and authenticates the iButton as a hardware token representing a specific end-user and/or valid software license, thus protecting against misuse or software piracy. Several 1-Wire adapters, the USB port (DS9490B), parallel port (DS1410E), or serial port (DS1411), can be used with the appropriate iButton to secure the software. (This is sometimes called a security dongle.)

The SDK includes several example programs with source code that show you how to use the software library with different iButton devices. There are two versions of the SDK download, one with example programs built for 32-bit Windows Vista^®, Windows^® XP, and Windows Server 2003 and one built for 64-bit Windows Vista x64, Windows XP x64, and Windows Server 2003 x64. Note however, the SDK can be built (using the necessary link files) for any platform supported by the 1-Wire Public Domain Kit.

The Software Authorization API is based on the simplest use scenario possible, and is designed to make integration into existing software code painless. The API provides three main services:

Initializing a device
Authenticating a device
Clearing a device (so it is no longer a valid part of the system)

Although Several 1-Wire adapters (iButton readers) work with the Software Authorization SDK, only the adapters that hold an iButton are recommended for software security devices (dongles). Thus to build a security device, the developer only needs to initialize an iButton, place it securely into the 1-Wire adapter, and ship it with the software

Recommended 1-Wire Adapters for Security Devices (Dongles)

1-Wire Adapter	Picture	Description
DS9490B		USB single-port iButton holder with internal 64-bit address. Can also be used as a key fob.
DS1411-009		Serial port iButton holder with internal 64-bit address.
DS1410E-001		Parallel port iButton holder with internal 64-bit address. Holds up to 2 iButtons.

*For iButton initialization, we recommend 1-Wire adapters that have an RJ11 cable out to multiple iButton receptacles, such as the DS9490R (USB) or DS9097U-009 (serial) coupled with the DS1402D-DR8 RJ11 Blue Dot.

iButtons/1-Wire Devices Supported

iButton/1-Wire Device	Description
DS1977	A password-protected EEPROM device capable of storing 32 kilobytes. Passwords provide both write- and read-protection.
DS1963S	A 512-byte NVRAM device with integrated SHA, eight write-only 8-byte secrets, and eight read-only 4-byte write-cycle counters for secure data verification. Data write-protection is achieved with the use of a digital signature that indicates if data is manipulated.
DS1961S/DS2432	(iButton/Chip) A 128-byte EEPROM device with integrated SHA engine and a write-only 8-byte secret which provides both data verification and write-protection.
