Microcontrollers add software-based
encryption
Software-based technology allows users to upgrade the microcontroller security in an installed application, in order to provide countermeasures against possible attacks.
NXP Semiconductors and NTRU have unveiled one of the first software-based encryption solutions for general-purpose ARM7 microcontrollers Software-encrypted microcontrollers can be used in various applications including credit card readers, entry access systems, ATMs and set-top boxes

HiPerSmart from Philips Semiconductors is the first 32bit smart computing platform to be manufactured using an advanced 0.18um CMOS process.
The software encryption-based technology will allow customers to upgrade the microcontroller security in an installed application, in order to provide countermeasures against possible attacks.
"Encryption and security solutions are particularly significant in an increasingly connected world where businesses have a need to authenticate and protect information", says Sheila Walker, Vice President of Business Development, NTRU.
"Embedded designers desire sophisticated encryption for even low-cost applications that may be carrying or transmitting sensitive information, which is what makes our partnership with NXP unique".

NXP's ARM-based microcontrollers feature in-application programming (IAP), which gives customers the option of upgrading their security algorithms in the field.
The popular LPC2300 and LPC2400 MCU series feature many communication peripherals, including Ethernet, CAN and USB, providing customers the flexibility to upgrade their security algorithms in installed applications.
Targeted to automotive, consumer, financial, medical and industrial end-equipment designers, software encryption provides the benefits of speed, flexibility and lower cost over time.
"We are very pleased to be working with NTRU and leveraging their knowhow as the encryption experts in order to help our customers protect their data", says Geoff Lees, Vice President and General Manager, Microcontroller Product Line, NXP Semiconductors.
"Software encryption gives our customers the flexibility to quickly respond to IP threats even before they happen and protect valuable IP".
The NTRU software security libraries for NXP's ARM technology-based microcontrollers provide the user tools including encryption and decryption of messages, digital signatures, and utilities protocols like key negotiation.
Core features include confidentiality, which allows the sender and receiver to be sure that the information is being shared only in the way they intend; authentication, which allows the receiver of the information to be certain where it came from; and integrity, which allows the receiver to verify that the message has not been altered in transit.
Specific functionality will include encryption, decryption, random number generation, digital signatures and other utilities protocols to achieve benefits such as confidentiality, authentication, integrity and nonrepudiation.
The algorithms include hash algorithms (SHA-1, MD5 and X9.82 RNG), symmetric-key encryption/decryption (AES, Triple-DES) and asymmetric-key encryption/decryption (RSA, DSA, Diffie-Hellman).
NTRU's software encryption libraries for NXP LPC2000 and LPC3000 microcontrollers are available immediately.
Development licence costs and royalty per unit is determined by and paid to NTRU.
Baseline royalty per unit pricing will be negotiable with NTRU exclusively.
