Abstract

A method including determining, by a first user device, a sharing encryption key based at least in part on a folder access private key associated with a folder and an assigned public key associated with a second user device; encrypting the folder access private key associated with the folder utilizing the sharing encryption key; and transmitting the encrypted folder access private key to enable the second user device to access the folder. Various other aspects are contemplated.

Claims (45)

1. A method, comprising:

generating, by a first user device, a sharing encryption key based at least in part on combining a folder access private key associated with a folder and an assigned public key associated with a second user device;

encrypting, by the first user device, the folder access private key associated with the folder utilizing the sharing encryption key; and

transmitting, by the first user device, the encrypted folder access private key to enable the second user device to access the folder.

2. The method of claim 1 , further comprising:

transmitting a request to receive the assigned public key associated with the second user device; and

receiving the assigned public key associated with the second user device based at least in part on transmitting the request.

3. The method of claim 1 , further comprising:

transmitting, by the first user device to the second user device, encrypted sample data, the sample data being encrypted by utilizing the assigned public key associated with the second user device; and

receiving, by the first user device from the second user device, decrypted sample data, the sample data being decrypted by utilizing an assigned private key associated with the second user device.

4. The method of claim 1 , wherein the folder access private key is included in a folder access key pair that includes a folder access public key, the folder access key pair being specific to the folder.

5. The method of claim 1 , further comprising:

transmitting a location associated with the folder and a folder access public key.

6. The method of claim 1 , wherein the sharing encryption key is a symmetric key.

7. A user device, comprising:

a memory; and

a processor communicatively coupled to the memory, the memory and the processor being configured to:

generate a sharing encryption key based at least in part on combining a folder access private key associated with a folder and an assigned public key associated with another user device;

encrypt the folder access private key associated with the folder utilizing the sharing encryption key; and

transmit the encrypted folder access private key to enable the other user device to access the folder.

8. The user device of claim 7 , wherein the memory and the processor are configured to:

transmit a request to receive the assigned public key associated with the other user device; and

receive the assigned public key associated with the other user device based at least in part on transmitting the request.

9. The user device of claim 7 , wherein the memory and the processor are configured to:

transmit, to the other user device, encrypted sample data, the sample data being encrypted by utilizing the assigned public key associated with the other user device; and

receive, from the other user device, decrypted sample data, the sample data being decrypted by utilizing an assigned private key associated with the other user device.

10. The user device of claim 7 , wherein the folder access private key is included in a folder access key pair that includes a folder access public key, the folder access key pair being specific to the folder.

11. The user device of claim 7 , wherein the memory and the processor are configured to:

transmit a location associated with the folder and a folder access public key.

12. The user device of claim 7 , wherein the sharing encryption key is a symmetric key.

13. A non-transitory computer-readable medium configured to store instructions, which when executed by a processor associated with a user device, configure the processor to:

generate a sharing encryption key based at least in part on combining a folder access private key associated with a folder and an assigned public key associated with another user device;

encrypt the folder access private key associated with the folder utilizing the sharing encryption key; and

transmit the encrypted folder access private key to enable the other user device to access the folder.

14. The non-transitory computer-readable medium of claim 13 , wherein the processor is configured to:

transmit a request to receive the assigned public key associated with the other user device; and

receive the assigned public key associated with the other user device based at least in part on transmitting the request.

15. The non-transitory computer-readable medium of claim 13 , wherein the processor is configured to:

transmit, to the other user device, encrypted sample data, the sample data being encrypted by utilizing the assigned public key associated with the other user device; and

receive, from the other user device, decrypted sample data, the sample data being decrypted by utilizing an assigned private key associated with the other user device.

16. The non-transitory computer-readable medium of claim 13 , wherein the folder access private key is included in a folder access key pair that includes a folder access public key, the folder access key pair being specific to the folder.

17. The non-transitory computer-readable medium of claim 13 , wherein the processor is configured to transmit a location associated with the folder and a folder access public key.

18. The non-transitory computer-readable medium of claim 13 , wherein the sharing encryption key is a symmetric key.

19. The method of claim 1 , wherein generating the sharing encryption key includes generating the sharing encryption key based at least in part on utilizing a symmetric key cipher.

20. The user device of claim 7 , wherein, to generate the sharing encryption key, the memory and the processor are configured to generate the sharing encryption key based at least in part on utilizing a symmetric key cipher.
