7.5.1. Security Key Types
Intel® Arria® 10 devices offer two types of keys—volatile and non-volatile. The following table lists the differences between the volatile key and non-volatile keys.
|Key Types||Key Programmability||Power Supply for Key Storage||Programming Method|
||Required external battery, VCCBAT 38||On-board|
|Non-volatile||One-time programming||Does not require an external battery||On-board and in-socket programming 39|
Both non-volatile and volatile key programming offers protection from reverse engineering and copying. If you set the tamper-protection mode, the design is also protected from tampering.
