Infineon’s New ORIGA™2 Authentication Chip with MIPI BIF Standard Interface Protects Mobile Device Users Better Against Counterfeit Components

Infineon Technologies (FSE: IFX/OTCQX: IFNNY) has added a product to the ORIGA™ family of authentication solutions: The new ORIGA™2 chip integrates a communication interface supporting the MIPI BIF standard defined by the MIPI Alliance. MIPI BIF (Battery Interface) is the first standardized single-wire interface for communication between the mobile device and battery pack. The standardization facilitates the development of intelligent batteries that authenticate and constantly monitor and report important battery parameters, such as temperature. This helps to enhance user’s protection from potentially dangerous counterfeit batteries in mobile devices such as smart phones or tablet computers. The mobile device for example will only operate with advanced features like fast charging, if the ORIGA™2 chip authenticates the battery as an original product.

The Infineon ORIGA™2 chip is also suitable for printer cartridges, replacement parts, medical disposables, network components or accessories such as earphones, speakers, docking stations and chargers. Increased key length and other features further increase the security of Infineon’s ORIGA™2 solution. In addition, the ORIGA™ Digital Certificate feature enables the provision of chip-individual keys. The ORIGA™2 chip uses asymmetric authentication based on elliptic curve cryptography (ECC) already introduced in ORIGA™1. ECC authentication utilizes two different keys: a public key on the host side, in the mobile phone for instance, and a private key on the battery side, which is protected in the ORIGA™ chip. This provides improved security at reduced system cost because on the host side the public key can be implemented in software without compromising security.

“Infineon’s ORIGA™2 solution brings significant benefits in clone prevention and temperature monitoring: For designers and developers of smart phones as well as for all other OEMs using batteries and accessories. The new MIPI BIF standard helps to Enhance User’s Protection from Counterfeit Mobile Device Components,” says Sandro Cerato, Vice President Power Management & Multimarket Division at Infineon Technologies.

The ORIGA™ chips provide battery and electronics manufacturers with counterfeit detection capability to prevent device failure or damage due to unauthorized components. Device users are protected from accidents and injuries possibly caused by non-approved, untested accessories and batteries – in notebooks or mobile phones, for instance.

Infineon’s ORIGA™2 chip (product name SLE95200) is designed for temperatures from -25 to +85 degrees Celsius and for an operating voltage range of 2.5 V to 4.8 V. It will be available from the fall of 2012 in an ultra-small chip-scale package and in a very small QFN package.
