SLE 66CX366PE
Security
Since the very beginning, security is an integrated part of Infineons product development, as proved by
various certificates (ITSEC, CC, Proton, VISA, ZKA, Mondex). The so called “integral security concept”
for the 66P series ensures:
A secret storage of any confidential code, data and keys
Protection against side channel attacks such as: Simple Power Analysis (SPA) , Differential Power
Analysis (DPA),
Protection against Differential Fault Analysis (DFA), Electromagnetic Emanation Attack (EMA) and
other possible HW or SW attacks
Peripherals
The CRC module allows the easy generation of checksums according to ISO/IEC 3309 (16-Bit-CRC). To
minimize the overall power consumption, the chip card controller IC offers a sleep mode. The UART
supports the half-duplex transmission protocols T=0 and T=1 according to ISO/IEC 7816-3. All relevant
transmission parameters can be adjusted by software, as e.g. the clock division factor, direct/inverse
convention and the number of stop bits. Additionally, the I/O port can be driven by communication routines
realized in software.
The Advanced Crypto Engine (ACE) is equipped with its own RAM of 700 bytes and supports all of today
known public-key algorithms based on large integer modular arithmetic. It allows fast and efficient
calculation either in HW or supported by software of e.g. RSA operations and EC (Elliptic Curves)
algorithms for key lengths up to 2048-bit.
For all of it’s crypto controller using the ACE, Infineon offers a tailor made RSA 2048-bit library. This library
is a powerful multifunctional crypto library for the SLE 66CXxxP family. It provides arithmetic functions for
easy programming the Advanced Crypto Engine (ACE). In addition it provides a full implementation of RSA
Sign, Verify and Key generation including powerful SPA/DPA and DFA counter measures. It supports RSA
up to 2048 bit key length.
The HW-DES module supports symmetric crypto algorithms according to the Data Encryption Standard in
the Electronic Code Book Mode.
The random number generator (RNG) is able to supply the CPU with true random numbers on all
conditions.
The advanced sensor concept includes various sensors for any kind of attack scenarios and even more
important a “Life Test ” for sensors.
As an important feature, the chip provides an on-chip security, which fulfills the strong security
requirements of a Common Criteria evaluation at an EAL5+ level.
In conclusion, the SLE 66CX366PE fulfills all the requirements of today's chip card applications, and is
especially designed for DDA payment and ID-applications incl. digital signatures.
The SLE66CX366PE integrates outstanding memory sizes, additional peripherals in combination with
enhanced performance and optimized power consumption on a minimized die size.
