3、 of such Standards and Publications shall not in any respect preclude any member or non-member of TIA from manufacturing or selling products not conforming to such Standards and Publications. Neither shall the existence of such Standards and Publications preclude their voluntary use by Non-TIA membe
4、rs, either domestically or internationally. Standards and Publications are adopted by TIA in accordance with the American National Standards Institute (ANSI) patent policy. By such action, TIA does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties ad
5、opting the Standard or Publication. This Standard does not purport to address all safety problems associated with its use or all applicable regulatory requirements. It is the responsibility of the user of this Standard to establish appropriate safety and health practices and to determine the applica
6、bility of regulatory limitations before its use. (From Project No. 3-0209, formulated under the cognizance of the TIA, TR-34.1 Subcommittee on Communications and Interoperability ).

32、 Link Nonce for CTR Mode 27 11 Scope TIA/EIA-1073 is a multi-part standard that when taken in total, defines the requirements for a Satellite Network Modem System using Time Division Multiplexing (TDM) and Multi-Frequency Time Division Multiple Access (MF-TDMA) signaling. The Satellite Network Modem
33、 System (SNMS) standard defines the technical requirements for meeting the functional capabilities described in TIA/EIA-157 1. The SNMS standard defines the requirements for Hub-Spoke as well as Mesh satellite network topologies operating over transponded/transparent satellite systems. The collectio
34、n of parts making up TIA/EIA-1073 is depicted below in Figure 1. The present document, SNMS Encryption Requirements (TIA/EIA-1073-002), provides the general requirements necessary to achieve security for hub-spoke and mesh network topologies. The general requirements that shall be met by the SNMS re
35、ference publications were developed by ETSI (European Telecommunications Standards Institute). These referenced publications are freely available at http:/www.etsi.org. The SNMS shall fully meet the DVB-S2 and DVB-RCS requirements in ETSI EN 301 790 and ETSI EN 302 307 2, 3 unless otherwise specifie
36、d by this document. In addition, the encryption requirements specify modifications to, additions to, and/or deletions to the specifications in 2, 3, and other requirements necessary to provide the capabilities described in TIA/EIA-157. These modifications use the same paragraph number system as in t
37、he reference documents. 2SNMS Network Layer Protocols(TIA/EIA-1073-001)DVB-RCS GuidelinesETSI TR 101 790 Satellite Network Modem System (SNMS) General Requirements(TIA/EIA-1073-000)DVB-RCSETSI EN 301 790 DVB-S2ETSI EN 302 307 SNMS Encryption Requirements(TIA/EIA-1073-002)IP Modem FCD(TIA/EIA-157)C2P
