Description: Fast SHA-1 Hash Core
To obtain more information or to obtain this core, please contact Helion Technology Ltd.
This high performance core implements the SHA-1 secure hash algorithm to NIST FIPS Publication 180-2. It is used in secure protocols and digital signature applications, where a large file must be compressed in a secure manner before being encrypted.
- Implements SHA-1 secure hash algorithm to NIST FIPS Publication 180-2
- Fast operation — each 512-bit block requires only 82 master clock cycles
- Performs automatic message length calculation and padding insertion
- Optional user initialization of IVs for efficient HMAC support
- HMAC wrapper available to make implementations quick and easy
- Optional state unload/reload feature for handling fragmented messages
- Simple external interface
- Supports Actel's ProASIC3 and Axcelerator device families
- 59% Utilization in ProASIC3 A3P250 device
- 24% Utilization in Axcelerator AX500 device
