PARIS – IP core designer Tiempo SAS and Cryptography Research Inc. said they have sealed an agreement regarding Differential Power Analysis (DPA) countermeasures patents.
Tiempo (Grenoble, France) said it is using Cryptography Research's DPA countermeasures to strengthen the security of its core designs used in chips for low-power embedded electronics and secured devices, e.g. power management, sensor networks, metering devices, RFIDs, smartcards with or without contact, as well as chips for consumer markets –mobiles, smartphones, e-books, netbooks.
DPA is a class of attacks that involves monitoring the fluctuating electrical power consumption of a target device and then using advanced statistical methods to derive cryptographic keys and other secrets. Strong countermeasures to DPA help protect tamper-resistant products used in applications such as banking, pay television, mass transit, secure ID and wireless telecommunications.
Cryptography Research said its patent portfolio includes more than fifty U.S. and international patents covering DPA and countermeasures. A license to these patents is required to make, use, sell, offer to sell, or import DPA-resistant devices. Tiempo is among the first European authorized developers of DPA countermeasures.
“Tiempo clockless design technology is very well suited for secured low-power applications. Thanks to the use of Cryptography Research's patented DPA countermeasures, Tiempo is now able to deliver what we consider to be the most secure and power efficient microcontroller and cryptoprocessor IP cores on the market,” stated Serge Maginot, Tiempo's CEO.
