Security ICs

 

Trust is what security is really all about today. Microchip security products make “trust” easy to embed in any system. Flexibility, advanced features, innovative cost effective architectures, and ultra-secure hardware defense mechanisms make Atmel hardware-based security devices an ideal way to add trust, by design.

 

CryptoAuthentication™ — Offers product designers an extremely cost-effective, easy to design, tiny, and ultra-secure hardware authentication capability.
Trusted Platform Module — The Microchip Trusted Platform Module (TPM) provides strong hardware-based public key (RSA) security on a single device for personal and tablet computers as well as embedded processor based systems.
CryptoMemory — The Microchip CryptoMemory® family offers a range of cost-efficient, high-security electrically erasable programmable read-only memory chips (EEPROMs) and host-side security for applications requiring comprehensive data protection.
CryptoRF — Microchip CryptoRF® is a 13.56MHz RFID device family employing a 64-bit embedded hardware encryption engine, mutual authentication, and up to 64Kbits of user memory.

CryptoAuthentication

A Crypto Element Device Family with Ultra-secure Hardware-based Key Storage

 

CryptoAuthentication Devices Keep it Real

 

Microchip CryptoAuthentication crypto element devices with hardware-based key storage ensure that a product, consumables it uses, firmware it runs, accessories that support it, and the network nodes it connects to are not cloned, counterfeited, or tampered with. Keeping products real helps maintain an OEM revenue flow by ensuring that only legitimate products can work in the host system and not used beyond their expiration.

 

Microchip offers the industry’s widest selection of authentication devices featuring hardware-based key storage and cryptographic countermeasures that can fight off even the most aggressive attacks. Because attackers cannot see secret keys that are stored in protected hardware, they cannot attack.

 

Key Features:

 

  • Cost-effective Symmetric and Asymmetric Authentication Solutions
  • Secure Hash Algorithm (SHA-2), Advance Encryption Standard (AES), and Elliptic Curve Cryptography (ECC) Cryptographic Algorithms
  • Built-in ECDSA and ECDH Protocols
  • Ultra-secure Hardware-based Key Storage
  • High Quality Random Number Generators (RNG)
  • Active Shield Over the Entire Device
  • Common Serial Interfaces
  • Tamper Monitors
  • Tiny Packages
  • And more…

Trusted Platform Module

Complete Security for PCs and Embedded Systems

 

The Microchip FIPS 140-2 Certified Trusted Platform Module (TPM) provides strong hardware-based public key (RSA) security for both personal computers and embedded processors on a single chip. It is a complete turnkey system that integrates industry-leading Microchip AVR® microcontroller architecture, Microchip EEPROM technology, and Microchip security technology. Implementing version 1.2 of the Trusted Computing Group (TCG) specification for TPMs, the chip supports secure boot via platform integrity measurements, intellectual property protection, authentication, and secure communications. The AT97SC* series is offered in three different interfaces: SPI, LPC, and I2C. All revisions are supported in both Commercial and Industrial Grades. The Trusted Platform Module Embedded Development Kit received a 2008 Readers Tech Choice Award from eg3, an independent news source devoted to electronic design.

 

 

Key Features:

 

  • Turnkey solution — The TPM includes integrated, protected nonvolatile storage for cryptographic keys, secrets, and authorization information.
  • Full TCG compliance — According to TCG, applications based on the trusted computing infrastructure exhibit superior security governance and risk management.
  • Hardware security — The TPM includes a high-quality hardware random number generator, active shielding, and a variety of tamper-detection and response circuits.
  • High performance — The TPM’s cryptographic accelerator can compute a 2048-bit RSA signature in 200ms.
  • Energy savings — The TPM supports SIRQ for interrupts and CLKRUN to permit clock stopping for power savings in mobile computers.
  • Software support — BIOS and hardware drivers are available for both Windows and Linux; third-party system and application software is also available.
  • Two interfaces — There is a 33 MHz LPC interface for PC integration and a 2-wire interface for non-PC and embedded computing systems.

CryptoRF

The Largest Selection of Memory Solutions for RFID

 

Microchip CryptoRF® is a 13.56MHz RFID (radio-frequency identification) device family equipped with a 64-bit embedded hardware encryption engine, mutual authentication capability, and up to 64Kbits of user memory. These low-cost chips are virtually impossible to copy and offer hardware security that is superior to software security solutions. CryptoRF ICs are ideal for applications that are prone to counterfeiting, require a permanent chain of ownership, or use contactless smart cards for cash transactions. They are also suitable for use in adverse environmental conditions where dust, dampness, or temperature extremes can cause problems for digital devices.

 

Key Features:

 

  • Safer than passwords — Mutual authentication between host and client is accomplished with a unique cryptogram that is randomly generated for each transaction.
  • Attack isolation — The key diversification scheme limits any attack to only one unit.
  • Multiple access levels — User memory can be divided into as many as 16 separate sections, allowing several different levels of read and write access.
  • Diverse packages — The chips are available in many different shapes and sizes; tags in a variety of shapes can be developed for high-volume applications
  • Host-side simplicity — The Microchip CryptoCompanion™ chip provides simple, plug-and-play authentication on a host (interrogator) device.
  • Development tools — Comprehensive reference designs, demonstration kits, and application software facilitate implementation into existing products.

CryptoMemory

Making EEPROMs a Safe Place for Sensitive Data

 

The Microchip CryptoMemory® family offers a range of cost-efficient, high-security electrically erasable programmable read-only memory chips (EEPROMs) and host-side security for applications requiring comprehensive data protection, including mutual authentication between devices and host. CryptoMemory chips are the world’s largest family of EEPROMs with a 64-bit embedded hardware encryption engine, four sets of nonreadable, 64-bit authentication keys, and four sets of nonreadable, 64-bit session encryption keys. The result: a truly secure means of preventing product counterfeiting and piracy. The chip family features a choice of memory densities and is easy to implement in a variety of applications.

 

Key Features:

 

  • Designer’s choice — The chips are available in memory densities ranging from 1 Kbit to 256 Kbits to accommodate diverse storage and cost requirements.
