Note: The
AN12570 "Quick start guide with Raspberry Pi"
describes how to build the
Plug & Trust Middleware in detail (see chapter 3.3. Build EdgeLock SE Plug & Trust
Middleware test examples).
4.8.3 How to configure the A5000 product specific SCP keys in the Plug & Trust
Middleware
A5000 is delivered with the default A5000 Platform SCP keys as shown in the table
below.

Table 4. 128-bit AES Default Platform SCP keys
By default the Plug & Trust Middleware is configured with default Platform SCP keys for
a different product. Therefore, it is required to change the default settings. For evaluation
purpose the MW supports to store the Platform SCP key in a plain text file. For further
details see Plug & Trust Middleware documentation chapter
11.10 Using own Platform
SCP03 keys
.
In this example we use the Linux environment variable
EX_SSS_BOOT_SCP03_PATH
to
define the Platform SCP key textfile (filename and location).
The following Linux commands can be used to create the Platform SCP key file
(a5000_scp_keys.txt):
echo ENC c9118500b5ffa1433a50226f489a0aa5 > a5000_scp_keys.txt
echo MAC 29d2fe28f7feeb153068be381f61bc01 >> a5000_scp_keys.txt
echo DEK 6124d38402118060ed910360fc5a4278 >> a5000_scp_keys.txt
Check the
a5000_scp_keys.txt
file content:
cat a5000_scp_keys.txt

Note:
In this example the Raspberry Pi is used for evaluation purpose only. Because
different host MCU/MPU platforms are providing different hardware security mechanisms
