New York public schools had also restricted teachers and students from using the platform, though the ban was recently rescinded.

įounded in 2014, Keybase is an encrypted messaging platform that allows users to securely swap data and cryptographically verify one another's identities on social media.īut while Zoom has seen an extraordinary jump in users, now numbering 300 million participants a day, since the coronavirus crisis forced millions of people and students to work from home, security has an issue.Ĭoncerns about the security of Zoom's platform have led companies including Elon Musk's SpaceX and Sweden's Ericsson to ban employees from using the platform. "We are also investigating mechanisms that would allow enterprise users to provide additional levels of authentication," Chief Executive Officer Eric Yuan wrote in a blog post.

Zoom said it was preparing a draft design of its encryption policy to be released May 22, when it plans to host discussions with cryptographic experts and customers, and integrate feedback into a final design before rolling the feature out to users. Shares of Zoom were up 5% at $157, after rising earlier as much as 8%. Separately, New York's attorney general, Letitia James, announced an agreement with Zoom over a range of issues, including enhanced privacy for educational accounts and updates to Zoom's policy on abusive conduct. The company said it had bought Keybase, a secure messaging and file-sharing service, for an undisclosed price as it seeks engineering expertise to deliver more robust encryption for its conferencing platform. Merging requires a completed review.Zoom has been one of the big beneficiaries of coronavirus lockdowns, with millions of workers and students using its video platform as they work and study from home.
