Objective short data sheet Rev. 03 — 24 January 2008 2 of 18 NXP Semiconductors P5Cx012/02x/40/73/80/144 family Secure dual interface and contact PKI smart card controller 1.3 Naming conventions 1.4 Cryptographic hardware coprocessors 1.4.1 FameXE coprocessor The approved and modular FameXE architecture supports the trend of increasing RSA keys with faster execution speeds as well as Elliptic Curve Cryptography (ECC) based on GF(p) or GF(2n) at best performance. FameXE supports RSA with an operand length of up to 8-kbit (up to 4-kbit with intermediate storage in RAM only). The FameXE PKI coprocessor supports 192-bit ECC key length that offers the same level of security as 2048-bit RSA. An ECC GF(2n) based signature, using a 163-bit key can be executed in less than 30 ms providing a security level comparable to 1024-bit RSA. The operand size for ECC, supported by FameXE, is only limited by the 2.5 KB size of the FXRAM. FameXE is easy to use and the flexible interface provides programmers with the freedom to implement their own cryptology solutions. A secured and CC EAL5+ certified crypto library providing a large range of required functions will be available for all devices in order to support customers in implementing public key-based solutions. 1.4.2 Triple-DES coprocessor The DES for widely used symmetric encryption is supported by a dedicated, high performance, highly attack resistant hardware coprocessor. Single DES and triple-DES, based on two or three DES keys, can be executed within less than 40 µs. Relevant standards (ISO/IEC, ANSI, FIPS) and Message Authentication Code (MAC) are fully supported. A secured crypto library element for DES is available. 1.4.3 AES coprocessor SmartMX is the first smart card microcontroller platform to provide a dedicated high performance 128-bit parallel processing coprocessor to support secure AES. The implementation is based on FIPS197 as standardized by the National Institute for Standards and Technology (NIST), and supports key lengths of 128-bit, 192-bit, and 256-bit with performance levels comparable to DES. AES is the next generation for symmetric data encryption and recommended successor of DES providing significantly improved security level. A secured crypto library element for AES is available.
