Rambus Inc said it signed a patent license agreement with digital security firm Gemalto.
“The agreement covers the use of Rambus patents covering Differential Power Analysis (DPA) Countermeasures, which protect devices and integrated circuits against DPA and other related side-channel attacks,” said Rambus.
“Specific terms of the agreement are confidential.”
Bret Sewell, senior vice president and general manager of the Rambus Security Division, said: “We are pleased to collaborate with Gemalto to provide the key technology elements critical for the protection of sensitive keys and data.”
DPA countermeasures, developed by Rambus Cryptography Research, consist of a broad range of software, hardware and protocol techniques that protect devices from side-channel attacks and are implemented in tamper-resistant products used in a variety of applications.
