Core network aspects 1

11.3 Communication security

Communication security relates to the provision of mechanisms to ensure that information is not unlawfully
diverted or intercepted.
In multiple access networks, it is recommended to employ modern technical mechanisms to ensure the
security of the underlying network. In eMMTel, effective methods should be taken to ensure information
security, for example, a firewall is recommended to be deployed, etc.

11.4 Data confidentiality

Data confidentiality relates to maintaining subscriber traffic confidentiality, control messages, as well as to
the management of traffic by cryptographic or other means.

In multiple access networks environments, the authentication information transmitted by the multiple
accesses is sensitive and confidential. If this information is stolen and tampered with, security threats may
occur. In eMMTel, the access signalling and access media are recommended to take some measures to ensure
data confidentiality in the multi-connection network environment.

11.5 Data integrity

Data integrity relates to maintaining subscriber traffic integrity, control messages, as well as to the
management of traffic by cryptographic or other means.

In eMMTel, when the subscriber traffic or control messages are lost, the eMMTel service cannot work
normally; data integrity checking technology is proposed to ensure data integrity. Integrity algorithms should
be used.
