After initial concerns about WiMAX trials, the differences between WiMAX and 3G have gradually diminished. Now, new questions regarding the security of WiMAX have emerged. Experts provide a concise and confident answer: WiMAX is secure. The WiMAX standard inherently supports more flexible and superior security compared to Wi-Fi standards.
Some individuals are uncertain as analysts and critics discuss standards like WiMAX, with some suggesting that WiMAX’s security may not be robust. This uncertainty may stem from the overly enthusiastic comments made by some telecommunications providers to promote their products, which could lead customers to doubt the quality and reliability of the offerings.
It is fair to say that security is a crucial feature distinguishing the WiMAX standard from others and the capabilities of WiMAX networks that providers showcase in their products.
However, it is important to understand that security for WiMAX is quite reliable and assured. Perhaps more importantly, WiMAX allows various telecommunications providers to add features that ensure better security than any competing wired broadband network, including security for government network applications. While typical residential network services may not require security, sectors like banking, healthcare, and government do, and WiMAX can accommodate these needs.
Recognizing the demand for security is vital when selecting current wireless broadband services. Both the IEEE organization and the WiMAX forum are committed to establishing a secure environment. WiMAX security supports two quality encryption standards: DES3 and AES, which are among the top priorities.
Essentially, all information transmitted over WiMAX networks must be secured using Counter Mode and the CCMP (Cipher Block Chaining Message Authentication Code Protocol). This protocol utilizes AES encryption to secure data transmission and authenticate integrated data.
There are numerous specific examples demonstrating WiMAX security; for instance, Alvarion (Israel) has integrated security features into its BreezeMAX system based on WiMAX standards, utilizing protocols and processes to ensure reliable system operation. WiMAX has also been deployed in many countries, receiving customer satisfaction.
In Vietnam, the government’s request for the Ministry of Information and Communications to grant trial licenses for commercializing WiMAX for VNPT, VTC, Viettel, and FPT reflects the efforts of many companies and experts in the IT and telecommunications fields. This demand is also indicative of the rapid development of technologies serving IT and telecommunications. Customers require more efficient, faster, and better tools, while businesses need new technologies to maintain their market position and enhance competitiveness, thereby attracting customers.
The technical specifications of WiMAX have been thoroughly reviewed by technology experts, and Vietnamese companies are preparing to offer services based on WiMAX technology. Therefore, customers can be completely assured of the security and viability of this technology. VMS – MobiFone, a member of VNPT, plans to provide WiMAX services starting in early 2007.
