Abstract
A method including determining, by a device, an assigned key pair including an assigned public key and an assigned private key; determining, by the device for a group associated with a folder, a group access key pair including a group access public key and a group access private key; encrypting, by the device, the group access private key by utilizing the assigned public key; and accessing, by the device, the folder based at least in part on decrypting the group access private key. Various other aspects are contemplated.
Claims20
A method, comprising:
- determining, by a user device, an assigned key pair including an assigned public key and an assigned private key;
- determining, by the user device for a group associated with a folder associated with encrypted content, a group access key pair including a group access public key and a group access private key;
- determining, by the user device, for respective content, a respective symmetric key and a respective content access key pair including a respective content access public key and a respective content access private key;
- encrypting the respective content, to determine the encrypted content, based at least in part on utilizing the respective symmetric key;
- encrypting, by the user device, the respective symmetric key for the respective content based at least in part on utilizing the respective content access public key;
- first encrypting, by the user device, the respective content access private key for the respective content based at least in part on utilizing the group access public key;
- second encrypting, by the user device, the respective content access private key for the respective content based at least in part on utilizing the assigned public key;
- encrypting, by the user device, the group access private key by utilizing the assigned public key;
- transmitting, by the user device for storage in correlation with the folder, the encrypted respective symmetric key, the first encrypted content access private key, the second encrypted content access private key, and the encrypted group access private key;
- and
- accessing, by the user device, the folder based at least in part on decrypting the group access private key.
