Abstract

A method including determining an assigned key pair associated with a device, the assigned key pair including an assigned public key and an associated assigned private key; determining an access key pair associated with content to be encrypted, the access key pair including an access public key and an associated access private key; encrypting the access private key using a combination encryption key determined based at least in part on the access private key and the assigned public key; encrypting a randomly generated key by utilizing the access public key; and encrypting the content utilizing the randomly generated key. Various other aspects are contemplated.

Claims (61)

1. A method, comprising:

determining an assigned key pair associated with a device, the assigned key pair including an assigned public key and an associated assigned private key;

determining an access key pair associated with content, the access key pair including an access public key and an associated access private key;

encrypting the access private key using a combination encryption key determined based at least in part on the access private key and the assigned public key;

encrypting a randomly generated key by utilizing the access public key; and

encrypting the content utilizing the randomly generated key.

2. The method of claim 1 , further comprising:

determining the combination encryption key utilizing an algorithm associated with a symmetric key cipher.

3. The method of claim 1 , wherein the combination encryption key is a symmetric key.

4. The method of claim 1 , further comprising:

decrypting the access private key by determining a combination decryption key based at least in part on the assigned private key and the access public key;

decrypting the randomly generated key by utilizing the access private key; and

decrypting the content utilizing the randomly generated key.

5. The method of claim 1 , further comprising:

receiving a master string of alphanumeric characters from the device; and

encrypting the assigned private key by utilizing a master key that is determined based at least in part on the master string of alphanumeric characters.

6. The method of claim 1 , further comprising:

receiving a master string of alphanumeric characters from the device; and

decrypting the assigned private key by utilizing a master key that is determined based at least in part on the master string of alphanumeric characters.

7. The method of claim 1 , wherein the randomly generated key is a symmetric key.

8. A device, comprising:

a memory; and

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

determine an assigned key pair associated with the device, the assigned key pair including an assigned public key and an associated assigned private key;

determine an access key pair associated with content, the access key pair including an access public key and an associated access private key;

encrypt the access private key using a combination encryption key determined based at least in part on the access private key and the assigned public key;

encrypt a randomly generated key by utilizing the access public key; and

encrypt the content utilizing the randomly generated key.

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

determine the combination encryption key utilizing an algorithm associated with a symmetric key cipher.

10. The device of claim 8 , wherein the combination encryption key is a symmetric key.

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

decrypt the access private key by determining a combination decryption key based at least in part on the assigned private key and the access public key;

decrypt the randomly generated key by utilizing the access private key; and

decrypt the content utilizing the randomly generated key.

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

receive a master string of alphanumeric characters; and

encrypt the assigned private key by utilizing a master key that is determined based at least in part on the master string of alphanumeric characters.

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

receive a master string of alphanumeric characters; and

decrypt the assigned private key by utilizing a master key that is determined based at least in part on the master string of alphanumeric characters.

14. The device of claim 8 , wherein the randomly generated key is a symmetric key.

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

determine an assigned key pair associated with the device, the assigned key pair including an assigned public key and an associated assigned private key;

determine an access key pair associated with content, the access key pair including an access public key and an associated access private key;

encrypt the access private key using a combination encryption key determined based at least in part on the access private key and the assigned public key;

encrypt a randomly generated key by utilizing the access public key; and

encrypt the content utilizing the randomly generated key.

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

determine the combination encryption key utilizing an algorithm associated with a symmetric key cipher.

17. The non-transitory computer-readable medium of claim 15 , wherein the combination encryption key is a symmetric key.

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

decrypt the access private key by determining a combination decryption key based at least in part on the assigned private key and the access public key;

decrypt the randomly generated key by utilizing the access private key; and

decrypt the content utilizing the randomly generated key.

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

receive a master string of alphanumeric characters; and

encrypt the assigned private key by utilizing a master key that is determined based at least in part on the master string of alphanumeric characters.

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

receive a master string of alphanumeric characters; and

decrypt the assigned private key by utilizing a master key that is determined based at least in part on the master string of alphanumeric characters.
