Another day, another data breach compromising personal data. Why don't they just encrypt? Encryption is easy, but being able to access your encrypted data and use it on all the devices you use and share it with your co-workers is hard. The Mathematical Mesh is an open infrastructure that addresses the missing piece in Public Key Infrastructure: the management of the private keys. Devices connected to a user's personal Mesh are automatically provisioned with precisely the set of keys, credentials, and data required to perform their function. The Mesh uses structural and threshold cryptographic techniques to achieve an unprecedented level of security without requiring the user to think about cryptography or security. The only configuration steps required to configure a device to use the Mesh replace prior network and platform configuration steps. And when the Mesh code is complete, these can be made as simple as a one-time QR code scan.
