Infineon's Security Controller 88 FamilyBy Infineon Technologies' new security controller 88 family is designed for multi-application chip cards used in electronic banking, mobile communications, and identity authentication. The new 88 family combines a 32-bit core architecture and an integral security concept to meet the requirements of multi-application systems. The first IC in the 88 family, the SLE88CX720P, has large fixed and re-programmable memory and Virtual Machine Language acceleration to execute application code written in JavaSC and other stack-oriented languages. The IC is based on a 32-bit RISC CPU running at frequencies of up to 66 MHz. This provides the performance headroom needed to assure that card suppliers' investments in software development can be deployed across a wide range of current and future systems. The 88 family is based on a workstation-like core architecture, incorporating on-chip data and instruction caches to support fast program execution by pre-fetching instructions. It accelerates all Virtual Machine-based chip card languages, including JavaSC, MultOS, and Windows Powered Smart Cards. The chip architecture also is optimized to run multiple tasks in parallel, including peripheral functions such as external communications through the on-chip UART and execution of data encryption and security functions. To meet requirements for the highest possible security, the 88 family's integral security concept combines multiple levels of physical protection and encryption support, including the industry's strongest DPA/SPA (Differential Power Analysis/Simple Power Analysis) countermeasures. The on-chip Memory Management Unit (MMU) incorporates hardware firewalls to isolate and protect applet code from other system elements. In order to support symmetric and asymmetric algorithms, the controller features powerful crypto coprocessors with the highest performance for DES (Data Encryption Standard), Triple-DES, RSA (Rivest, Shamir, Adlemen), and elliptic curves algorithms. RSA algorithms with key lengths of 1.024 bits are processed in 65 milliseconds without Chinese Remainder Theorem (CRT). To reduce card suppliers' development costs and speed time-to-market, Infineon also provides a Platform Support Layer (PSL), which is a complete set of low-level drivers for all peripherals and a crypto library for RSA, elliptic curves, and AES (Advanced Encryption Standard). The first member of the 88 family, the SLE88CX720P, includes 240 Kbytes of ROM, 80 Kbytes of EEPROM, 8 Kbytes of RAM, a crypto coprocessor, and UART with two I/Os. It operates at a voltage range of 1.8 to 5.0 V, in full compliance with ETSI specifications. Engineering samples of the SLE88CX720P will be available in December 2001 with volume production planned in Q1 2002. The product is shipped as sawn wafers or packaged in modules. Link: |
