A biztonság és a felügyelet új arca

Biometrikus arcfelismerés

Ankur Tomar – Farnell Technical Support

A mai helyzetben különösen kényszerítő szükségszerűséggé vált a gyanúsan viselkedő személyek vagy
a gyanús viselkedés felismerése olyan – biztonsági szempontból kiemelt fontosságú – helyeken, mint a repülőterek,
vasútállomások, kormányzati vagy más középületek. Ez az oka annak, hogy ma már – egyebek közt – a videoalapú,
biometriai azonosító és arcfelismerő rendszerek is világszerte a biztonsági fenyegetések kezelésének legfontosabb
eszközei közé tartoznak.

IP-alapú videomegfi gyelő rendszerek

Az internetalapú technológiák az adattovábbításon kívül egyre inkább használatosak valós idejű multimédiainformációk
továbbítására is. A személyi- és vagyonbiztonságot egyre inkább veszélyeztető környezetben fokozódik
az igény a könnyen telepíthető, nagy területen szétosztott, könnyen rendszerré integrálható eszközökből álló
biztonsági videomegfi gyelő és eseményrögzítő rendszerek iránt. A cikk azt mutatja be, hogy az IP-technológia
hogyan épül be a biztonságtechnikai eszközökbe.

Application Notes- Protecting the R&D Investment—Two-Way Authentication and Secure Soft-Feature Settings- AN3675

tech1 — Fri, 30 Oct 2009 15:44:35 GMT

In the age of identity theft and faked IDs, achieving positive identification is of paramount importance. This is not only true for individuals, but also applies to electronic products. System vendors need to protect their products against hacker attacks from the "outside" and ensure that the security is not compromised on the "inside" through cloned hardware. The key to realizing these diverging requirements is authentication.

This article explains the concept of authentication and specifically a Maxim solution in the form of secure memories to provide secure control and protection from application requirements including intellectual property protection, embedded HW/SW license management, secure soft-feature and status setting, and tamper-proof data storage.

Application Notes- Are SHA-1 Devices Still Secure Enough?- AN3522

tech1 — Fri, 30 Oct 2009 15:39:55 GMT

In 2005, a group of Chinese researchers attacked the strength of the Secure Hash Algorithm (SHA-1). This white paper discusses that attack and shows that, although the algorithm is slightly less collisionresistant than previously thought, the security of the SHA-1 memory devices from Maxim is not affected. Thus, the company's SHA-1 memory devices (DS1963S, DS1961S, DS2460, DS28CN01, DS28E01-100 and DS2432), will continue to provide a low-cost, effective solution for accessory/peripheral authentication and tamper-proof, verifiable memory applications.

Application Notes- Increasing System Security by Using the DS5250 as a Secure Coprocessor- AN3294

tech1 — Fri, 30 Oct 2009 15:37:09 GMT

This application note describes how to use the Dallas Semiconductor DS5250 High-Speed Secure Microprocessor as a secure coprocessor to protect passwords, PINs, encryption keys and other critical data.

The DS5250 employs triple-DES bus encryption, elaborate tamper sensors, and battery-backed SRAM to form a cryptographic boundary that shields valuable intellectual property. A user-configurable external tamper sensor allows the system architect to extend the DS5250's security shield to include the application's enclosure, protecting all of the system components if desired.

Application Notes- Requirements of Remote Keyless Entry (RKE) Systems- AN3395

Remote keyless entry (RKE) has captivated automobile buyers, as evidenced by the popularity of RKE on new automobiles and as an after-market item. This application note provides an overview of RKE systems and discusses how they meet requirements such as range, battery life, reliability, cost, and regulatory compliance.

It shows some circuits and design approaches and offers some predictions for future systems, which will include

two-way communications.

AN2033 - Maxim - SRAM-Based Microcontroller Optimizes Security

tech6 — Fri, 30 Oct 2009 12:39:15 GMT

APPLICATION NOTE 2033 SRAM-Based Microcontroller Optimizes Security

Abstract

It is shown that nonvolatile (NV) SRAM is the most secure memory for storing secure data. By encrypting the memory with DES or triple DES, a cryptographic boundary can be erected that renders the secure information impervious to hackers. The volatile nature of the SRAM can be further protected by using tamper-reactive sensors that will erase the encryption keys as a response. Financial applications such as PINpads rely on the automatic program and data memory encryption features to secure data. The DS5250 is a high-performance, secure 8051 microcontroller that uses the unique properties of secure SRAM to protect sensitive data.

AN3976 - Maxim - Embedded Security Going Forward

tech6 — Fri, 30 Oct 2009 12:37:23 GMT

APPLICATION NOTE 3976 Embedded Security Going Forward

Abstract:

Equipment manufacturers and designers are facing many new design challenges due to the continuing need for increased data security in many of today's electronic systems. At the heart of the problem is the need to either implement security and antitamper countermeasures into a new application that never before required such mechanisms, or to avoid the introduction of new design variables into proven existing security circuitry. This is compounded with the emergence of new security standards and the the everincreasing demands the certification bodies require. The challenges of maintaining size and cost competitiveness further complicate this critical design requirement. In order to meet these challenges, Maxim has introduced a family of innovative devices designed to specifically address new and emerging security standards in a controlled and layered approach. The following describes how these new devices allow legacy designs to be enhanced with additional security, while minimizing the costs and risks of designing entirely new embedded security platforms.

APPLICATION NOTE 4167 Cookbook for Analog Video Filtering in Camera Systems

Abstract

Analog video filtering is widely used at the output stage in video camera applications, such as CCTV, security camera, digital still cameras (DSCs), and digital video camcorders (DVCs). As products are reduced in size and power, designers are moving away from discrete solutions to more integrated, one-chip solutions. This article explains different filter amplifier configurations for several popular DACs in the video camera market. It is an easy-touse guide for Maxim's various integrated video filter amplifiers that satisfy a wide range of video application requirements.
