Abstract
Split-key based cryptography techniques are provided for data protection and synchronization across multiple computing devices of a user. A method performed by a first device of a user comprises encrypting a data using a randomly-generated data encryption key; wrapping the data encryption key with a public key of a second device of the user; and sending the encrypted data and the wrapped data encryption key of the first device wrapped with the public key of the second device to a server. The server sends the encrypted data and the wrapped data encryption key of the first device wrapped with the public key of the second device to the second device. The first device or the second device can access the encrypted data by reconstructing their respective private key using a predefined number of shares obtained using a key splitting scheme.
