NEW DELHI -- India is reluctant to allow Huawei Technologies to participate in the country's 5G rollout, despite the Chinese telecom giant's recent proposal to sign a pledge guaranteeing there will be "no back door" into its equipment that could threaten national security.
A back door is a means by which normal security can be bypassed in order to gain access to a network. They are often installed in hardware and software so programmers can troubleshoot problems, but can also be exploited by hackers.
