I have an interest in encryption technology and read this New York Times article with great interest: N.S.A. Foils Much Internet Encryption.
The bottom line: If you keep sensitive data in the cloud or send it over the Internet:
- Choose your encryption technology carefully. Understand its limitations and weak points.
- Create your own keys and keep them close to your chest. You can’t trust your service provider if they have installed a backdoor or if any government or other party leans on your provider hard enough.
Excerpts from the article:
Because strong encryption can be so effective, classified N.S.A. documents make clear, the agency’s success depends on working with Internet companies — by getting their voluntary collaboration, forcing their cooperation with court orders or surreptitiously stealing their encryption keys or altering their software or hardware.
…
Microsoft asserted that it had merely complied with “lawful demands” of the government, and in some cases, the collaboration was clearly coerced. Some companies have been asked to hand the government the encryption keys to all customer communications, according to people familiar with the government’s requests. Executives who refuse to comply with secret court orders can face fines or jail time.
…
Since Mr. Snowden’s disclosures ignited criticism of overreach and privacy infringements by the N.S.A., American technology companies have faced scrutiny from customers and the public over what some see as too cozy a relationship with the government. In response, some companies have begun to push back against what they describe as government bullying.
…
Google, Yahoo, Microsoft and Facebook have pressed for permission to reveal more about the government’s secret requests for cooperation. One small e-mail encryption company, Lavabit, shut down rather than comply with the agency’s demands for what it considered confidential customer information; another, Silent Circle, ended its e-mail service rather than face similar demands.In effect, facing the N.S.A.’s relentless advance, the companies surrendered.
Ladar Levison, the founder of Lavabit, wrote a public letter to his disappointed customers, offering an ominous warning. “Without Congressional action or a strong judicial precedent,” he wrote, “I would strongly recommend against anyone trusting their private data to a company with physical ties to the United States.”
