Figure 2 -- Symmetric Key Management Module of RFID System
In the Figure 2, key generation system finishes key generation and dispersion in the
RFID system; key distribution system finishes distribution and entry of key in RFID tag
and reader; key shall be used in the secure cryptographic device, which includes
secure access module in RFID reader and RFID tag.
7 General Requirements for Symmetric Key
Management
The system shall take necessary security protection measures; so that meet the
requirements for protecting the key security.
The symmetric key stored in the RFID tag shall not be read.
The symmetric key stored in the RFID reader shall be stored in the secure access
module and shall not be read.
The following contents in the key management such as key generation, storage,
dispersion, distribution, entry, backup, restoring, verification, use, update, filing,
cancellation and destruction, etc. shall meet the relevant requirements for the
competent department of national cryptographic management.
8 Use Requirements for Symmetric Key
8.1 ID authentication
8.1.1 UID authentication
The RFID tag shall store the check code jointly established by UID of RFID tag and
relevant application information; while the RFID reader shall store the key for
generating such check code.
8.1.2 Challenge response authentication
The key used for the challenge response authentication must have the uniqueness.
The key used for the challenge response authentication and stored in RFID tag shall
be generated through the dispersion of derivation key and UID of RFID tag.
The RFID reader shall store the derivation key used for challenge response
authentication; can dispersedly generate the key consistent with the key used for the
challenge response authentication through reading the UID of the RFID tag; it is stored
Appendix A
(Informative)
Key Management Example of RFID System
This Appendix describes a key management example, which is applicable to the RFID
system with security level of Level-3.
A.1 Application requirements of system
The key management requirements of this application are based on the following basic
conditions.
a) The system involves several RFID tag issuers (referring to the originators of the
RFID tag information); each issuer has a unique code to distinguish
(manufacturer ID);
b) When leaving the factory, each RFID tag has a UID (chip UID);
c) Perform secure access control to the two information memory areas
(distinguished by tag information area 1 and tag information 2) in the RFID tag;
each information memory area shall have independent access control
permission; distinguish the writing from reading;
d) The RFID tag has the special key memory area, which shall be written into once
rather than being rewritten;
e) The data stored in the information memory area of the RFID tag shall use special
key to encrypt;
f) The algorithm in the reader has.
1) The symmetric cryptographic algorithm SM7 is used for information encryption
of two-way ID authentication with RFID tag, access control and transmission
process;
2) The symmetric cryptographic algorithm SM1/SM4 is used for information
storage encryption and key dispersion;
3) The asymmetric cryptographic algorithm SM2 is used for generating the digital
signature of information, verifying the signature;
4) The cryptographic hash function SM3 is used for generating information
summary.
SKi) of the RFID reader itself. Such key pairs are generated in the RFID reader; the
generated private key is securely stored in the RFID reader; the public key is uploaded
to the cryptographic device of the key management center; the public key certificate is
obtained by signifying the derivation private key; then enter into the RFID reader;
namely, the form storage of the public key certificate (PubCerti) of the RFID reader.
A.2.2 Key dispersion
Adopt the key dispersion method to generate the whole keys entered into the RFID tag
and partial key (with the writing permission) entered into the RFID reader.
Since KW1 and KW2 respectively have writing permissions a...
