Security
The set of security features has been tailored to fit the requirements of M2M applications purposes combined
with enhanced reliability for these applications.
Encrypted storage of any confidential code, data and keys is supported.
Basic protection against side channel attacks such as: Simple Power Analysis (SPA), Differential Power
Analysis (DPA).
Basic protection against Differential Fault Analysis (DFA) / Fault Induction Attacks.
A customer specific transport key combined with a unique loader concept secures the logistic flow until
card issuing.
Peripherals
The SCP (Symmetric Crypto Processor) module supports symmetrical crypto algorithms according to the
Data Encryption Standard (DES) in the Electronic Code Book Mode, as well as Cipher Block Chaining, while
the AES (Advanced Encryption Standard) component of the SCP module performs AES-compliant
operations for three different key lengths.
The Interrupt and Peripheral Event Channel Controller (ITP) can process interrupt requests from different
sources to run an interrupt service routine (ISR). Data can be directly transferred between memory locations
with a minimum of CPU activity for fast interaction with peripherals using so-called Peripheral Event
Channels (PECs). The channels can be assigned individually to peripherals or chained together to enable
continuous transfer without handover delay between the channels.
The enhanced CRC module allows the easy generation of checksums according to ISO/IEC 3309 (16-Bit-
CRC) and offers a loadable initialization vector for a better Java support.
To minimize the overall power consumption, the chip card controller IC offers a sleep mode.
The improved UART supports the half-duplex transmission protocols T=0 and T=1 according to ISO/IEC
7816-3 as well as a larger FIFO and a clock division factor of 8. 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 pseudo random number generator (PRNG) is able to supply random numbers.
The watchdog timer (WDT) is a circuit that monitors controller operation by automatically initiating a security
reset if a specified period without an adequate response elapses after occurrence of a hardware or software
irregularity.
In conclusion, the SLM76CF5120P fulfills all requirements of today's M2M smart card applications. In
addition, it offers a powerful platform for multi application cards based on Java.
The SLM76CF5120P integrates outstanding memory sizes and peripherals in combination with enhanced
performance and optimized power consumption on a minimized die size, together with resistance to extreme
conditions, such as high temperature, EEPROM cycling at high temperature, vibration or humidity, which are
characteristics in M2M applications.
