H(e)NB is able to provide new services with higher data rate in a low cost. Operators have already indicates their interest in this area. Study of H(e)NB has already started in 3GPP in order to investigate the feasibility of developing a standard solution for H(e)NB. Security is an critical aspect of H(e)NB, so it is necessary to investigate security issues of H(e)NB.

The present document identifies special security threats of H(e)NB and study the countermeasures to these threats. The study should include, but not be limited to, threat analysis of H(e)NB, mutual authentication and security protection between H(e)NB and rest of network, maintenance of the security context between H(e)NB and rest of network, security requirements on the H(e)NB, provisioning of security credentials on the H(e)NB, security solution for verifying the location of the H(e)NB etc. With regard to security protection between the H(e)NB and the rest of the network, bandwidth efficiency should be taken into consideration.

The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

• References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific.
• For a specific reference, subsequent revisions do not apply.
• For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.
