Ever since 2012, Americans have been told that Huawei is a national security threat because of a law in China that could force Huawei to gather intelligence (read “spy”) on behalf of the Chinese government. As a result, U.S. lawmakers have accused the manufacturer of building back doors into its phones and networking equipment for the express purpose of allowing the company to send collected data to Beijing.

Huawei allegedly keeps its lawful interception interfaces hidden from its carrier-clients

The Journal notes that companies producing networking equipment must include a way for law enforcement officials to tap into a network. Each country has its own laws pertaining to this capability, and authorized employees at wireless carriers are allowed to access these “lawful interception interfaces.” But U.S. officials say that Huawei keeps the location of these interfaces secret, even to its customers. One U.S. official notes, “Huawei does not disclose this covert access to its local customers, or the host nation national-security agencies.” Other rival equipment makers do not have this ability to hide their interfaces from carriers or from the government in the country where the equipment is being employed. National Security Adviser Robert O’Brien says, “We have evidence that Huawei has the capability secretly to access sensitive and personal information in systems it maintains and sells around the world.”

In a statement, Huawei says that it “has never and will never do anything that would compromise or endanger the security of networks and data of its clients. We emphatically reject these latest allegations. Again, groundless accusations are being repeated without providing any kind of concrete evidence.” A senior Huawei official also refutes the allegations by stating that “The use of the lawful interception interface is strictly regulated and can only be accessed by certified personnel of the network operators. No Huawei employee is allowed to access the network without an explicit approval from the network operator. Network access without operator permission “is extremely implausible and would be discovered immediately.”

Because of fears that the company spies on its clients and others, Huawei was placed on the U.S. Commerce Department’s entity list last May. That prevents the firm from accessing the U.S. supply chain it spent over $11 billion on in 2018. It also blocks Huawei from receiving the license it needs to use Google Mobile Services on its phones. While this isn’t such a big deal in China where most of Google’s apps are banned anyway, it does have an impact on global sales of affected devices. Huawei has developed its own ecosystem using Huawei Mobile Services which is expected to debut this spring with the launch of the Huawei P40 series. HMS will include Huawei’s own App Gallery and the company has sought participation from App developers.
