METHODS AND APPARATUS TO SECURELY SHARE DATA

摘要

Methods and apparatus to securely share data are disclosed. An example includes retrieving, by executing an instruction with a processor at a first computing device associated with a first user of a cloud service, an encrypted archive file and a wrapped encryption key from a second computing device associated with a second user of the cloud service, the wrapped encryption key wrapped with key data associated with the first user of the cloud service at the second computing device, unwrapping the wrapped encryption key with the key data to obtain an unwrapped encryption key, and decrypting the encrypted archive file with the unwrapped encryption key to obtain a decrypted archive file.

主权项

1. A first computing device associated with a first user of a cloud service, comprising:
a trusted execution environment to:
retrieve an encrypted archive file and a wrapped encryption key from a second computing device associated with a second user of the cloud service, the wrapped encryption key wrapped with key data associated with the first user of the cloud service at the second computing device; andunwrap the wrapped encryption key with the key data to obtain an unwrapped encryption key; and an encryption engine to decrypt the encrypted archive file with the unwrapped encryption key to obtain a first archive file representative of first data from the second computing device.
