CTIA Super Mobility Week - Las Vegas - September 2014 - The rapid growth of the proprietary mobile device office (BYOD) market, coupled with the explosive growth of small base station deployments in 4G networks, There is an emerging IT security threat that is urgently needed in the global marketplace. This is the opinion of Dr. MarTIn Nuss, Chief Technology Officer (CTO) of Vitesse Semiconductor, at the 4G World Conference. Vitesse provides advanced chip solutions for global telecommunications networks, enterprise networks and Internet of Things (IoT) networks. Leading supplier of solutions.
Dr. Nuss has more than 20 years of technical and management experience and is a recognized industry expert in Ethernet technology. He is currently a Director of the World Wireless Communications Solutions Alliance (ATIS) and a Fellow of the Optical Society of America. He told many audiences at the 4G World Congress that when small base stations become an integral part of 4G LTE, LTE-Advanced (LTE-A) deployments and carrier-grade heterogeneous network (HetNet) strategies, they are very accessible. Sex makes it a hacker's easy target.
Dr. Nuss noted that while mobile networks are inherently more secure than WiFi hotspots, small cell base stations emerging to improve LTE and LTE-A capacity pose a new security risk. Small base stations are more susceptible to interference and hacking than traditional macro base stations because they are installed in places such as streets. He mentioned that the backhaul of small base stations often also relies on the network of third-party access service providers, who may not have the same security standards as wireless carriers. Therefore, the small base station itself needs to be authenticated on the service provider network, and the data stream needs to be encrypted before being transmitted back to the service provider, including accessing the service provider's network through a third party. When encryption technologies such as IPSec can be used to implement this function, such as stream-based expansion to Ethernet technology such as MACSec (IEEE 802.1AE), it may be more cost-effective for small base station deployments.
Talking about the high-precision timing requirements of LTE and LTE-A networks, Dr. Nuss also mentioned the importance of timing safety, because GPS timing is difficult to accept in places where reception conditions are not good or do not exist. This is the situation that small base stations face in dense urban corridors. There is no direct line of sight between these sites and the satellites or indoors where GPS signals cannot pass through the wall. The weakness of small base stations that are susceptible to GPS interference and spoofing raises another concern. He went on to mention that packet-based network timing using IEEE 1588 (1588) is a reasonable alternative to GPS in small base stations, as long as 1588 can be protected. Encryption and timing accuracy are often incompatible, but modern stream-based MACsec implementations do not have to withstand this opposition, and cable-rate AES encryption is now combined with nanosecond-accurate network timing.
Because small cell deployments are still very important for the continued growth and success of mobile technology, these technological developments are critical. The large amount of data traffic on those base stations comes from a range of mobile devices. Dr. Nuss cited the data in the IDC report in the comments. In 2014, smartphone shipments will reach 1.25 billion units, an increase of 23% over the previous year; The annual shipments of telephones are expected to reach 1.8 billion by 2018 - when small base stations will be everywhere, with careful network planning and awareness, security threats have been overcome.
“With the true potential of being able to build a more connected and more productive workforce, BYOD is revolutionizing the connectivity of the enterprise,†said Martin Nuss, chief technology officer at Vitesse. “However, as an industry, we need to focus on overcoming this potential security threat so that the 4G LTE network can continue to prosper and the business community can benefit from BYOD while ensuring its network security.â€
