Public Key Accelerator

As part of INSIDE Secure’s award-winning silicon Intellectual Property (IP) product portfolio, the EIP-28 is a range of Public Key Accelerators operating as co-processors to offload Public Key operations from the Host processor.

特色

Low- to high-performance accelerator for Public Key operations, up to 4160-bit modulus size for modular exponentiations and 768-bit modulus for prime field ECC operations
Nine different configurations are available ranging from 19k (PKCP only) to 515k (dual 33-stage LNME) NAND2 gate equivalents (excluding memories) – the performance ratio between these extremes is up to a factor of 50 (depending on the operation)
Performs high-level Public Key signature generation / verification & key negotiation operations with little involvement of the Host processor
SECDED ECC support option for selected memories
Basic bus slave interface providing access to control/status registers and Public Key Accelerator data and local firmware program RAMs (program ROM is an option) – the functional interface is identical for all configurations
Security-conscious design: PROT hardware protection against basic side channel attacks is standard (can be removed on request)
Hardware zeroization of CSPs
