17、.iv ISO/IEC 2014 All rights reserved ISO/IEC 13157-1:2014(E) Introduction This International Standard specifies common NFC Security services and a protocol. This International Standard is a part of the NFC Security series of standards. The NFC-SEC cryptography standards of the series complement and

18、use the services and protocol specified in this International Standard. This second edition has removed Annex B because it has been included in ISO/IEC 18092:2013 and it allows implementation on generic NFC connections.

19、 information exchange between systems NFC Security Part 1: NFC-SEC NFCIP-1 security services and protocol 1 Scope This International Standard specifies the NFC-SEC secure channel and shared secret services for NFCIP-1 and the PDUs and protocol for those services. NOTE This International Standard doe

20、s not address application specific security mechanisms (as typically needed for smart card related use cases and standardized in the ISO/IEC 7816 series). NFC-SEC may complement application specific security mechanisms of ISO/IEC 7816. 2 Conformance Conformant implementations implement one or more o

21、f the services specified in this International Standard, using the security mechanisms from the NFC-SEC cryptography part identified by the selected Protocol Identifier. 3 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispens

35、C 7498-1. Figure 1 NFC-SEC architecture NFC-SEC Users invoke and access the NFC-SEC services through NFC-SEC Service Access Points (NFC- SEC-SAP). NFC-SEC entities obtain NFC-SEC-SDUs (requests) from NFC-SEC Users and return NFC-SEC- SDUs (confirmations) to them. This International Standard specifie

36、s the Secure Channel Service (SCH) and the Shared Secret Service (SSE). To provide the NFC-SEC services, Peer NFC-SEC entities exchange NFC-SEC-PDUs by conforming to the NFC-SEC protocol over NFC-SEC connections. Peer NFC-SEC entities send and receive NFC-SEC-PDUs through NFC Service Access Points (

37、NFC-SAP). A NFC-SEC-PDU consists of NFC-SEC Protocol Control Information (NFC-SEC-PCI) and a single NFC-SEC-SDU. 8 Services This Clause specifies two services, SSE and SCH, that NFC-SEC provides to the NFC-SEC User. When invoked, these services enable the cryptographic protected transmission of NFC-

38、SEC User messages between the peer entities by means of a protocol described in Clause 9. Shared secrets established with the services specified below shall be cryptographically uncorrelated from any shared secrets established beforehand or afterwards. 8.1 Shared Secret Service (SSE) T he SSE est ab

39、lishes a shared secret bet ween t wo peer NFC-SEC Users, which t hey c an use at t heir discret ion. Invocation of the SSE shall establish a shared secret by the key agreement and key confirmation mechanisms, according to the NFC-SEC cryptography part that defines the PID.4 ISO/IEC 2014 All rights r

40、eserved ISO/IEC 13157-1:2014(E) 8.2 Secure Channel Service (SCH) The SCH provides a secure channel. Invocation of the SCH shall establish a link key, by derivation from a shared secret established by the key agreement and key confirmation mechanisms, and shall subsequently protect all communications

41、 in either direction across the channel, according to the NFC-SEC cryptography part that defines the PID. 9 Protocol Mechanisms The NFC-SEC protocol comprises the following mechanisms. Figure 2 specifies the sequence of the protocol mechanisms. 9.1 Key agreement The peer NFC-SEC entities shall estab

42、lish a shared secret using ACT_REQ and ACT_RES, according to the NFC-SEC cryptography part that defines the PID. 9.2 K e y c onfirmation The peer NFC-SEC entities shall verify their agreed shared secret using VFY_REQ and VFY_RES, according to the NFC-SEC cryptography part that defines the PID. 9.3 P

43、DU security PDU security is a mechanism of SCH service only. The peer NFC-SEC entities shall protect data exchange using ENC, according to the NFC-SEC cryptography part that defines the PID. This mechanism shall comprise one or more of the following, as specified in the respective NFC-SEC cryptograp

44、hy standard: Sequence Integrity, conforming to the requirements of 12.3; Confidentiality; Data integrity; Origin authentication. 9.4 Termination The peer NFC-SEC entities shall terminate SSE and SCH using TMN.
