Cryptoprocessors IP cores: RSA & ECC
TPKA (Tiempo public key accelerator), is an accelerator for RSA and ECC encryption. It implements key routines in order to perform complex ciphering algorithms within embedded systems.
Key benefits
RSA-ECC accelerator block diagram
- Ultra-low power consumption
- Ultra-low current peaks
- Work at low and variable voltage
- Resistant to power and fault attacks
Key Features
- Fast execution of standard RSA and ECC ciphering and deciphering algorithms
- Fully asynchronous and delay insensitive
- Available as Verilog netlist[1] ready for P&R
- Optional: Verilog netlist[1] secured against hardware attacks
- Optional: Verilog netlist[1] strengthened for ultra-low noise and ultra low EMI
Applications
Targeted applications are chips for smartcards (with or without contact), RFID, tags, systems embedding NFC technology and other secured applications.
