Everyone has secrets to protect. In today’s digital age, whether safeguarding personal messages, business communications, or confidential state information, end-to-end encryption (E2EE) offers essential security and peace of mind.
E2EE ensures that your communications remain private from internet service providers and the operators of messaging or video conferencing applications. Messages are encrypted on the sender’s device and only decrypted by the recipient, making them unreadable to unauthorized parties while in transit. This prevents access by any entity, including law enforcement or corporate insiders.
Digital encryption is rooted in robust mathematics rather than mere assurances. The RSA algorithm, introduced in 1977, pioneered modern encryption by relying on the complexity of factoring large numbers into their prime components. Since then, various algorithms have emerged, utilizing intricate mathematics to enhance cryptographic security.
The true strength of E2EE lies not just in its technical implementation, but in how it upholds democracy and human rights across the globe. As Matthew Feeney from the UK privacy group Big Brother Watch states, “There are individuals in perilous regions depending on encryption to preserve their lives.” Additionally, even in recognized democracies, freedom is vulnerable. Feeney warns that those who claim “I have nothing to hide” should take heed of history’s lessons.
Many governments view E2EE unfavorably because it blocks surveillance, similar to how postal services safeguard letters. Notably, UK governments have attempted to ban E2EE; most recently, Prime Minister Keir Starmer reversed a controversial request for a backdoor into Apple following a public outcry.
Feeney acknowledges the uncertainty surrounding the potential for E2EE to be compromised, as intelligence agencies typically do not disclose their capabilities. Concerns loom regarding the advent of quantum computing, which may soon breach current encryption algorithms. However, cryptography continues to evolve, with emerging mathematical solutions challenging outdated algorithms. “Governments may wield power, but they can’t override the laws of mathematics,” Feeney asserts.
