CryptoAuthentication™ Product Uses
Abstract
Companies are continuously searching for ways to protect property using
various implementations of security; however the cost of implementation can
drive companies away from effective hardware solutions to less secure
software solutions. With the introduction of the AT88SA10HS/102S devices,
affordable hardware security is now in reach and can provide exceptional
protection for:
CryptoAuthentication
Product Uses
AT88SA10HS
AT88SA102S

Confidential file protection
Embedded software anti-cloning
Development system anti-cloning
Media transmission encryption
USB security dongles
Securing wireless or other radio transmission nodes
Authentication for data over power lines
Physical access control
Electronic lockers
Hardware user authentication
Consumable product authentication
Battery authentication.
1. Overview
This document provides an introduction to the Atmel AT88SA10HS/102S
CryptoAuthentication devices. These exceptional devices enable solutions to
countless problems across many industries. The use cases outlined in this
document will provide a brief description of possible applications for the
AT88SA10HS/102S devices and how they can be implemented.
2. AT88SA10HS/102S Introduction
To understand the operations and applications explained later in this
document you will first need to have a basic understanding of the
AT88SA10HS/102S devices and how they work. The AT88SA10HS and
AT88SA102S were developed to work together. The AT88SA102S is
designed to be embedded in the product that is protected or authenticated
(client) and the AT88SA10HS device is designed to be placed in the
validating system (host). The AT88SA102S client device can be used with or
without the host side device. When the AT88SA102S is used without the
host side AT88SA10HS chip the host microcontroller must store secret
information in order to perform the validation of the client. Having the secret
information stored in the embedded source code presents a security risk as
the secrets may be ascertained with little effort. For the strongest security
the AT88SA10HS host device should be used; this keeps the customer’s
secret keys protected securely in hardware away from hackers attempting to
reverse engineer the host embedded code.
