With the advent of 3G mobile systems a serious effort has been made to create a consistent security architecture based on the threats and risks a 3G system faces. UMTS security algorithms. Figures security framework in 3G mobile networks and then security requirements needed by stakeholders as well as end-users. The security architecture along with security mechanisms proposed by Universal Mobile Telecommunication System (UMTS) network, have also been analyzed.
This allows the operator to more flexibly divide the usage of available spectrum according to traffic patterns. With the advent of 3G mobile systems a serious effort has been made to create a consistent security architecture based on the threats and risks a 3G system faces. UMTS security algorithms. Figures
3G UMTS bandwidth. UMTS uses wideband CDMA as the radio transport mechanism and the UMTS frequency channels are spaced by 5 MHz. The UMTS signal bandwidth is normally considered to be 5 MHz but this figure includes the 0.58 MHz guard bands either side. 3G Network - Analysis & Simulation. Analysis and simulation of UMTS, or Universal Mobile Telecommunications System, a 3rd generation mobile technology with increased spectral efficiency and high bandwidth can support greater data rates for voice and video data to the wireless end users.

It was hence decided that the 3G security architecture will be based on this. At the same time it was decided that the shortcomings present in the second generation systems will have to be removed. existing mobile systems and to develop a new security architecture specifically to be used in UMTS. This early work was subsequently taken forward into the Third Generation Partnership Project (3GPP) and this will be the basis for the Release 99 deployment of 3G systems.
• Network Access Security • Network domain security • User domain security • Application domain security • visibility, configurability of security. Network Access Security helps protect air interface and also provide 3g subscribers to access the 3g network securely. In UMTS authentication, key 'K' is shared between network and UE.

UMTS is designed to interoperate with GSM networks. To protect GSM networks against man-in-middle attacks, 3GPP is considering to add a structure RAND authentication challenge. UMTS Subscriber to UMTS Network. Both the network and the mobile station supports all the security mechanisms of UMTS. Authentication and Key agreement is as follows −
• The network architecture can be divided into subsystems based on the nature of traffic, protocol structures, physical elements. • Conceptual 3G. Launched in 2001, and based upon the GSM standard, 3G is the third generation of mobile communications. Standardized by the 3GPP as the Universal Mobile Telecommunications System (UMTS), 3G provides faster download speeds to that of previous generations of up to 3.1Mbps. Security Information.
