Encryption Backdoors: The Global Cybersecurity Dilemma
Friday, May 2, 2025 2:20 pm ET
3min read In the digital age, encryption has become an indispensable tool for safeguarding personal information and communications. However, governments around the world are increasingly demanding backdoors into encrypted data, claiming that these vulnerabilities are necessary for national security and law enforcement. Earlier this year, the UK government’s backdoor requirement led apple to withdraw its encrypted backup services from the country. In France, proposed “Narcotrafic” legislation would compromise encryption in an attempt to tackle drug trafficking. While attacking encryption in the name of law enforcement is not a new trend, it is a dangerous one—one that could threaten the privacy, security, and personal information of millions of people. Unless governments understand the weight of what’s at stake, it is a trend we can only expect to see more of.
An encryption backdoor is a type of exceptional access that a platform gives third parties—such as law enforcement and government officials—to the content of encrypted communications. This can exist as a “middle box,” which decrypts the data at a central server, then re-crypts it and sends it to the intended recipient. This is significantly less secure than end-to-end encryption, which services such as WhatsApp and Signal use. If you send a message to a friend on WhatsApp, the message is encrypted on your device. It can then only be decrypted on your friend’s device using a unique key, ensuring that only you and your friend (not even WhatsApp!) can read the messages. End-to-end encryption is the most secure kind of encryption that you can use.
Imagine you are going on vacation, and your friend comes over to water your plants. Instead of giving your friend the key to your house, making it accessible only to her, you leave it under a rock. Your friend knows it’s there, but it’s not obvious to everyone. However, if someone knows you’re away, they can poke around, find the hidden key, and let themself in. This is how encryption backdoors work. If someone knows that you are using a service with encryption backdoors, they may be able to exploit that and access your data. While the intention was to make that backdoor accessible only to authorized groups (like law enforcement), in reality, this is almost never the case. Once a vulnerability exists, communication is no longer secure. This is why creating backdoors weakens encryption for everyone.
More and more governments are jumping on the bandwagon of demanding encryption backdoors. With these guidelines in place, fewer people can use end-to-end encrypted services, which we believe are crucial for protecting your data. Additionally, even if end-to-end encrypted service providers are forced to build backdoors, malicious third parties will still be able to use unbreakable encryption. While building and operating an encryption system may not necessarily be easy, it is possible. The mathematical theory behind encryption is public knowledge, and numerous open-source, readily available reference implementations of encryption algorithms exist. If someone is determined enough, there are ways for them to get around backdoor orders. This means that governments would be compromising the privacy and security of millions of law-abiding citizens, with no guarantee that it would actually affect the criminals they claim to be targeting.
The long-term implications for global cybersecurity if multiple governments demand encryption backdoors are significant and multifaceted. According to Professor Nigel Smart at Zama, "backdoors don’t just threaten individual privacy, but could backfire on governments and cause a global security risk." This statement underscores the potential for widespread vulnerabilities that could be exploited by malicious actors, including hackers and hostile nations. One of the primary concerns is the "domino effect" of backdoor demands. As Joseph Lorenzo Hall of the Internet Society predicts, "one nation’s backdoor demand triggers copycat policies globally." For instance, the UK government's secret order to Apple to build a backdoor into their Advanced Data Protection (ADP) service highlights this risk. Apple's response to disable ADP in the UK to safeguard the cybersecurity of millions of Apple users around the world demonstrates the potential for a global security risk. If one government demands a backdoor, others may follow suit, leading to a cascade of weakened encryption standards worldwide.
The implications for international relations are also profound. The UK government's demand for a backdoor to access the iPhone encrypted cloud data of ALL accounts, irrespective of who the owner was, and where the phone was located, raises serious questions about data sovereignty. As the Washington Post article claims, "Why should the UK government have access to the data of other countries’ citizens, and companies?" This demand not only undermines the trust between nations but also sets a dangerous precedent where one country's actions could lead to a global race to the bottom in terms of cybersecurity standards.
Moreover, the political dilemma of backdoors is exacerbated by the potential for mission creep. As mentioned, "special scanning software like this risks ‘mission creep.’ By this, we mean a government led by Party X could expand its use to monitor conversations or data related to supporters of Party Y, or for any other purpose." This could lead to increased surveillance and potential human rights violations, further straining international relations.
In summary, the long-term implications for global cybersecurity if multiple governments demand encryption backdoors include widespread vulnerabilities, a potential domino effect of weakened encryption standards, and strained international relations. The demand for backdoors by one government can set a dangerous precedent, leading to a global race to the bottom in terms of cybersecurity standards and potentially undermining data sovereignty and human rights.
Encryption is a powerful tool for protecting sensitive personal information, and we believe it should be available to everyone. Encryption protects financial transactions and banking information. It protects the personal safety of marginalized groups. It protects our sensitive medical information. It protects electricity grids. We all want to stop criminals, but action must be taken without compromising the security that we all rely on to keep data safe online. Backdoors create a major vulnerability that isn’t worth the risk. Explore encryption resources.
