Cryptography Research and Infineon Technologies Sign License Agreement for Differential Power Analysis Countermeasures

  
    
  
  
    
      Cryptography Research Inc. (CRI) and Infineon Technologies AG (FSE/NYSE: 
      IFX) today announced they have signed a license agreement on a security 
      technology for tamper-resistant semiconductors. Under the agreement, 
      Infineon will license CRI’s patents for 
      countermeasures to Differential Power Analysis (DPA) and technology and 
      patents related to CRI’s CryptoFirewall™ 
      to help further expand its own expertise and portfolio.
    
    
      With the agreement, Infineon gains the right to use CRI's patents and 
      use CRI’s complete portfolio of patents 
      concerning countermeasures to DPA and related attacks worldwide. “Infineon 
      is recognized internationally for their leadership position in 
      developing security chips for the smart card industry,” 
      said Paul Kocher, president and chief scientist at CRI. “We 
      are pleased that Infineon has licensed our patents covering DPA 
      countermeasures.”
    
    
      “Confidential data stored inside security 
      controllers and smart cards are protected against a multitude of attack 
      scenarios. Our strategy for integrating protective mechanisms that 
      represent the most advanced technological developments is a main success 
      factor. The license to CRI’s patents enables 
      Infineon to provide all solutions of Infineon’s 
      side-channel countermeasure portfolio,” said 
      Dr. Helmut Gassel, Vice President and General Manager of the Chip Card 
      and Security ICs Business Unit at Infineon Technologies AG. “Along 
      with energy efficiency and communication, security is one of the three 
      focus areas of Infineon.”
    
    
      DPA is a type of “side-channel” 
      attack that involves monitoring variations in a device’s 
      electrical power consumption. It then uses statistical methods to 
      extract secret cryptographic keys. Many security applications and 
      leading certification standards such as Common Criteria require 
      side-channel attack countermeasures. Security-certified products are 
      used in banking, conditional access, mass transit, identification, 
      telecommunications and other applications. In combination, hardware and 
      software countermeasures form an ideal synergy against side-channel 
      attacks.
    
    
      CRI and Infineon have also agreed to integrate CRI’s 
      patented CryptoFirewall™ into select products 
      of one of Infineon’s secure microcontroller 
      platforms. The CryptoFirewall™ provides an 
      extension to reinforce conventional conditional access systems and 
      hardware-based authentication solutions.
