Demand for the femtocell is largely credited to the surge in a more always best connected communication conscious public. 3GPP define new architecture and security requirement for Release 9 to deal with femtocell, Home eNode B referred as HeNB. In this paper, the authors analyze the HeNB security with respect to mutual authentication, access control, and secure key agreement. Their analysis pointed out that a number of security vulnerabilities have still not been addressed and solved by 3GPP technical specification. These include eavesdropping, man-in-the-middle attack, compromising subscriber access list, and masquerading as valid HeNB. To the best of their knowledge, any related research studying HeNB security was not published before.
