Atmel Crypto

Products Portfolio

system security solution options for a wide variety

of applications. The Portfolio consists of both client

and host hardware security ICs, which provide

authentication, encryption and secure data

storage capabilities.

Why hardware security? Confidential data or

secrets stored by unsecured means, such as in

standard memories, are vulnerable to attack and

exposure. Hardware security ICs include many

sophisticated design features specifically aimed

at keeping confidential data and core secrets

safe from hackers, thereby protecting corporate

revenue, valuable intellectual property and limiting

potential liability exposure.

System security is only as strong as the weakest

link. This well-known phrase should remain in

the forefront of any system developer’s mind as

they conceptualize a secure system design. Many

systems today are deployed with a hardware

security solution on the client side, while the host-

side secrets are stored in unsecured memories

(Figure 1). For those who recognize this host-

side implementation as a potential weakness,

Atmel offers host-side hardware security

companion ICs specifically designed to eliminate

this weakness (Figure 2). Crypto Products host

companion ICs implement the host algorithm in

hardware and securely store and manage the

host secrets, thereby strengthening the system-

level security and reducing development time.

The Crypto Products Portfolio is ideally suited for

a variety of applications, and in some cases more

than one product in the Portfolio can provide a

solution for a given application. For example, if

an application requires both authentication and

secure memory storage in a wired environment,

If a contactless interface is desired,

Reader IC, is an excellent choice. In cases where

the strength of a 256-bit key size is preferred,

Lastly, when a high security standards-based

(TPM) is a great choice.
