This module should only be used for low power (router) devices
|
|
without hardware AES acceleration (e.g. caam crypto). It reduces the
|
|
size of the AES tables from 16KB to 8KB + 256 bytes and mitigates
|
|
timining attacks. Nevertheless it might be not as secure as other
|
|
architecture specific assembler implementations that work on 1KB
|
|
tables or 256 bytes S-boxes.
