Introduction

1.1 Purpose

This is a non-proprietary Cryptographic Module Security Policy for the Dallas

Semiconductor DS1955B Java™-powered Cryptographic iButton® (Java iButton). This

security policy was prepared as part of FIPS 140-1 certification of the Java iButton. FIPS

140-1 (Federal Information Processing Standards Publication 140-1 --

Security

Requirements for Cryptographic Modules)

gives U.S. Government requirements for

cryptographic modules, and defines the Security Policy as:

“A precise specification of the security rules under which the cryptographic module must operate,

including rules derived from the security requirements of this standard, and the additional security

rules imposed by the manufacturer.”

The Java iButton provides extraordinary security, meeting all

FIPS 140-1 level 3

requirements,

and some level 4 requirements. This security policy describes how the Java

iButton meets these requirements, and how it can be operated in a secure fashion.

1.2 For more information

This document describes the operations and capabilities of the DS1955B Java-powered

Cryptographic iButton in the technical terms of a FIPS 140-1 cryptographic module

security policy.

For more detailed information about the Java iButton, please visit the iButton web

site at

http://www.ibutton.com.

The web site contains non-technical descriptions

of Dallas iButton products, technical specifications, product offerings, iButton

functionality, iButton developer information, and much more.

Fore more information about the FIPS 140-1 standard and validation program

please visit the NIST web site at

1.3 Terminology

In this document the Dallas Semiconductor DS1955B Java-powered Cryptographic

iButton is referred to as the DS1955B, Java iButton (JiB), cryptographic module, Java-

powered Crypto iButton, or module. The JiB is also referred to as simply “iButton”,

although this term also applies collectively to many other iButtons such as the DS1990,

DS1994, or DS1920.
