Using the A71CH Configure tool 16
A71CH Configure tool The A71CH Configure tool is a command line tool that supports the insertion of credentials into the A71CH. A71CH Secure Storage e.g. i.MXUltraLite Development PC Key pair #0 Key pair #2 Public key #0 Configuration APDU Host MCU commands Key pair #1 Key pair #3 Public key #1 commands A71CH Sym key #0 Sym key #4 Public key #2 Configure tool Serial port Config keys (3) Sym key #1 Sym key #5 I 2 C A71CH (SSH possible) General purpose Sym key #2 Sym key #6 Host Library storage Sym key #3 Sym key #7 e.g. TeraTerm command line bash tool Monotonic Monotonic counter #1 counter #0 Command line syntax: The command line syntax uses: a mandatory command name <cmd-n>, followed by e.g. A71CH mini PCB an optional command qualifier <cmd-q>, followed by '0 to n' (option, value) pairs. > <cmd-n> [<cmd-q>] [-option <option-value>]* 17
A71CH Configure tool: Info command Info command 2 1 > info [all|device|cnt|pair|pub|sym| status ] A71CH Echo the status of the A71CH or its stored credentials to the console > info status Secure Storage Key pair #0 Key pair #2 Public key #0 Key pair #1 Key pair #3 Public key #1 1 Sym key #0 Sym key #4 Public key #2 2 3 4 Config keys (3) Sym key #1 Sym key #5 3 Sym key #2 Sym key #6 4 Sym key #3 Sym key #7 General purpose storage Monotonic Monotonic 5 counter #1 counter #0 5 6 6 18
A71CH Configure tool: Generate ECC key pair Generate ECC key pair command: 1 > gen pair -x < int > Generate ECC key pair in index #0: A71CH > gen pair -x 0 1 Secure Storage Show public key pair generated in index #0: Key pair #0 Key pair #2 Public key #0 > info pair 2 Key pair #1 Key pair #3 Public key #1 Sym key #0 Sym key #4 Public key #2 Config keys (3) Sym key #1 Sym key #5 Sym key #2 Sym key #6 Sym key #3 Sym key #7 General purpose storage Retrieve public key command: Monotonic Monotonic counter #0 counter #1 > get pub -c < hex_value > -x < int > -k < keyfile.pem > Retrieve public key pair from index #0 and store it in myPublicKey.pem file ECC key pair > get pub -c 10 -x 0 -k myPublicKey.pem Secret key pair Public key pair 19
A71CH Configure tool: Inject an ECC key pair Generate a device key pair (e.g., using OpenSSL): 2 Generate ECC parameters: > openssl ecparam -name prime256v1 -out eccparams A71CH Generate myDeviceKeyPair keys: > openssl ecparam -in eccparams -genkey -noout -out Secure Storage myDeviceKeyPair.pem Key pair #0 Key pair #2 Public key #0 1 Key pair #1 Key pair #3 Public key #1 Sym key #0 Sym key #4 Public key #2 Config keys (3) Sym key #1 Sym key #5 Inject key pair command: Sym key #2 Sym key #6 > set pair -x < int > [-k < keyfile.pem > | -h < hexvalue_pub > -h < hexvalue_priv >] Sym key #3 Sym key #7 General purpose storage Monotonic Monotonic Inject myDeviceKeyPair in slot #1 : counter #0 counter #1 > set pair – x 1 – k myDeviceKeyPair.pem 2 ECC key pair Secret key pair Public key pair 20
