Describe the nature, extent, and scope of the Necessary Claims (attach additional pages, if necessary):
The present claims are related to an encoding method of security-relevant information (in case: the security level)
in a frame to be communicated by a sender in a secure communication system, such as to allow easy extraction ofsecurity-relevant information (in case: the security level) by its recipient(s), thus facilitating flexible cryptographic
processing hereof.

protection level applied to the frame, key identifying information, algorithmic information, and other securityrelated information).
Portion(s) of the Proposed Specifications that involve Necessary Claims:
All outgoing and incoming frames that require security on the NWK Layer (Clause 5) and the APS Layer(Clause 6).
More particularly, this refers to clauses of the ZigBee Alliance Security Specification, v0.92(03/322r12ZB), including the following:
Clause 5:
Frame Security (5.1), Secured NPDU Frame (5.2).
Clause 6:
Frame Security (6.1), Key Establishment (6.2), Transport-Key Services (6.3), Update-Device Services(6.4), Remove Device Services (6.5), Request Key Services (6.6), Switch Key Services (6.7), Secured
APDU Frame (6.8), Command Frames (6.9).
Clause 7:
Common Frame Header Format (7.1). Security Parameters (7.2).
Clause 8:

2. The Member shall disclose any terms and conditions applicable to the license of any Necessary Claims (including
without limitation, any Necessary Claims of an Affiliate or a Non-Member):Certicom has two patent applications that are pertinent to the Zigbee Alliance Security ServicesSpecification, Revision 12, 03/322r12ZB, v0.92. These patent applications, filed in Canada and the US,
are listed in section D of this Declaration. Certicom will offer licenses to this technology at US$0.005 (onehalf US cent) per Zigbee implementation that includes Zigbee Alliance Security Services Specification,
Rev 12, 03/322r12ZB, v0.92. For example, if a manufacturer is developing a chip or device that
implements the Zigbee Alliance Security Services Specification, Revision 12, 03/322r12ZB, v0.92,
Certicom will receive a fee of US$0.005 (one half US cent) for each chip or device. As an alternative, inorder to simplify the overall pricing model, Certicom will consider pooling with other Zigbee Alliancemembers that are also declaring fee-based licensing of their Intellectual Property in Zigbee Alliance
Specifications v0.92. In a pooling model, each holder of intellectual property in the pool will receive a tobe-negotiated portion of the overall fee that is commensurate with contribution.
