Abstract

A memory device is provided. The memory device includes a memory configured to store information. The memory device also includes a memory controller in communication with the memory. The memory controller is configured to encrypt the information to define a parameter and access an account on a second memory device based on the parameter to gain access to content. The content is stored in the second memory device and the memory device and the second memory device are configured to be removably coupled to a computing device.

Claims

1. A computing device removably coupled with a first memory device (SIM Card) storing information and a second memory device storing content, an account protecting the content from unauthorized access, and a binding configuration specifying how a parameter needed to authenticate to the account is to be generated from the information, the computing device comprising:

a memory; and

a processor in communication with the memory, the processor being configured to;

retrieve the information from the first memory device;

retrieve the binding configuration from the second memory device;

generate the parameter to authenticate to the account from the information based on the binding configuration; and

authenticate to the account on the second memory device based on the parameter and gain access to the content after authenticating to the account;

wherein the first memory device is a smart card.

2. The computing device of claim 1, wherein the computing device is a mobile phone.

3. The computing device of claim 1, wherein the information is an identifier associated with a mobile phone.

4. The computing device of claim 1, wherein the parameter is a nonce, the nonce being configured for use in generating an authentication key.

5. The computing device of claim 1, wherein the parameter is an authentication key.

6. The computing device of claim 1, wherein the information is a network identifier.

7. A method for accessing content, the method comprising:

performing the following in a host device removably coupled with a first memory device storing information and a second memory device storing content, an account protecting the content from unauthorized access, and a binding configuration specifying how a parameter needed to authenticate to the account is to be generated from the information;

retrieving the information from the first memory device;

retrieving the binding configuration from the second memory device;

generating the parameter to authenticate to access the account from the information based on the binding configuration; and

authenticating to the account on the second memory device based on the parameter and gaining access to the content stored in the second memory device after authenticating to the account;

wherein the first memory device is a smart card.

8. The method of claim 7, wherein the computing device is a mobile phone.

9. The method of claim 7, wherein the information is an identifier associated with a mobile phone.

10. The method of claim 7, wherein the parameter is a nonce, the nonce being configured for use in generating an authentication key.

11. The method of claim 7, wherein the parameter is an authentication key.

12. The method of claim 7, wherein the information is a network identifier.

13. The method of claim 7, wherein the content is configured to be decrypted by a key stored in the second memory device.

14. The method of claim 13 further comprising receiving decrypted content from the second memory device after accessing the account.

15. The method of claim 13, wherein the content is configured such that the parameter alone is insufficient to decrypt the content.

16. The method of claim 13, wherein the second memory device is further configured to, in response to the account being accessed, use the key stored in the second memory device to decrypt the content.
