Key Pair Generation
Each index location of the device corresponds to one ECDSA key pair. The detailed
steps are as follows:
：
a)
Specifies the key location based on the indicated key index range.
Generate ECDSA key pair
------------------
Generate new ECDSA key pair according to key index.
Please input the key index or key index range(1-100, for example:1,3,5-12), or [Return(R)] >11
b
Select the bit size of the key.
Generate ECDSA key pair
------------------
Select the bit size of the key, from 256 bits to 521 bits.
_|___________________________________
1| 256

3| 521
Select bit size of the key(Default[256]), or [Quit(Q)] [Return(R)] [Previous Step(P)] [Next
Step(N)]>1
c)
The generated key pair will be encrypted by the system protection key and saved to the
key storage area.

Key Pair Deletion
Follow the prompts to enter the key index and delete the RSA key pair for the
specified key index location.
