This document describes a crypto suite based on elliptic curve cryptography (ECC) for the ISO/IEC 18000 series of standards protocol. In particular, this document specifies the use of elliptic curve Diffie-Hellman (ECDH) key agreement in a secure channel establishment and the use of elliptic curve digital signature algorithm (ECDSA) in an authentication mechanism.This document specifies a crypto suite for ECDSA-ECDH for air interface for RFID systems. The crypto suite is defined in alignment with existing air interfaces.This document defines a mutual authentication method and methods of use for the cipher. A Tag and an Interrogator can support one, a subset, or all of the specified options, clearly stating what is supported. Key update is not supported in this document.ECDSA-ECDH cipher is a high-weight security protocol especially for active RFID system, aiming at meeting those scenarios with high level security requirement.
