Battery Interface Addresses Market Needs
• Mobile device battery industry
produced 1.5 billion batteries last
year – all using non-standard,
proprietary battery interfaces
• A commonly accepted battery
interface will save design time &
effort, improve time to market,
reduce chipset space and improve
cost margins
• Low cost, single-wire interface is
the only one in the industry for
mobile devices

EDN Europe; March 2006
Companies are working to strengthen
anti-counterfeiting efforts to protect
brand integrity and consumers from
potentially dangerous, counterfeit products.
Why Authentication ? To protect end customers from dangerous clones !
Head line examples:
• S Korea probes 'cell phone death'
• Exploding mobile phone kills man in China
• Laptop explodes at Japanese conference

Security has many components and it all comes down to the weakest point
1. System Security – Asymmetric Elliptic Curve Cryptography
2. Hardware security
3. Security of Production & Personalization sites, supply chain.
