5 Unleashing the potential of the Internet of Things

Requirements Explanation

Security • It is required to support key management schemes for USN
applications and services.
• It is recommended to support scalable key management
schemes for USN applications and services operating with
large sensor networks.
• It is recommended to provide security for the aggregated data
when sensed data from two or more applications and services
are integrated in infrastructure networks for the creation of
new services.
• The security approaches for the support of USN applications
and services are recommended to be consistent with the
general approach for security in NGN.
• In addition to data security, the USN communication
infrastructure is recommended to provide information
transport security for protection against well-known passive
and active attacks. Protocols for information transport are
required to be resilient to attacks.
• Depending on the specific USN application security
requirements, a means for intrusion detection is required.

Identification, authentication and • It is required to support identification, authentication and
authorization authorization for users to access USN applications and
services based on the security level of service data.
• It is required to support different levels of authentication for
different types of data based on the requirements of USN
applications and services.
• The USN end-users can optionally identify and authenticate
network providers and USN service providers.
Accounting and charging • It is required to support different accounting and charging
policies according to different data transaction types of USN
applications and services.

I.3 Mapping table of the requirements and the extended NGN functions
Clause I.1 defines the NGN capabilities to be extended to satisfy the requirements of
[ITU-T Y.2221]. This clause allocates proper functions of NGN which are defined in
[ITU-T Y.2012] to support the capabilities.
