Abstract

In one or more embodiments, one or more systems, methods, and/or processes may provide, to a device coupled to an information handling system, a request for salt data; may receive the salt data from the device; may determine a first position in an application that is executed by at least one processor of the information handling system; may determine a second position in the application, different from the first position; may determine a hash value of the application between the first position and the second position; may encrypt, utilizing a private encryption key, the salt data and the hash value as encrypted data; may provide the encrypted data to a buffer associated with the application; may retrieve the encrypted data from the buffer; and may provide the encrypted data to the device.

Claims

1. An information handling system, comprising:

at least one processor; and

a memory medium, coupled to the at least one processor, that stores instructions executable by the at least one processor, which when executed by the at least one processor, cause the information handling system to;

provide, to a device coupled to the information handling system, a request for salt data;

receive the salt data from the device;

determine a first position in an application that is executed by the at least one processor;

determine a second position in the application, different from the first position;

determine a hash value of the application between the first position and the second position;

encrypt, utilizing a private encryption key, the salt data and the hash value as encrypted data;

provide the encrypted data to a buffer associated with the application;

retrieve the encrypted data from the buffer; and

provide the encrypted data to the device.

2. The information handling system of claim 1, wherein the instructions further cause the information handling system to combine the salt data and the hash value.

3. The information handling system of claim 1, wherein, to encrypt the salt data and the hash value as the encrypted data, the instructions further cause the information handling system to utilize an elliptic curve cryptographic process to encrypt the salt data and the hash value as the encrypted data.

4. The information handling system of claim 1, wherein, to determine the hash value of the application between the first position and the second position, the instructions further cause the information handling system to utilize at least one of an Abreast Davies-Meyer, a Davies-Meyer, a MD2, a MD4, a MD5, a RIPE-MD, a GOST Hash, a N-HASH, a HAVAL, a SHA, and a SNEFRU.

5. The information handling system of claim 1, wherein, to determine the first position in the application, the instructions further cause the information handling system to search for a marker within the application.

6. The information handling system of claim 5, wherein the marker includes at least one of a universally unique identifier (UUID) and a globally unique identifier (GUID).

7. The information handling system of claim 5, wherein, to search for the marker within the application, the instructions further cause the information handling system to search for the marker within the application starting at an address of an instruction pointer of the at least one processor.

8. A method, comprising:

receiving, from an information handling system, a request for salt data;

in response to the receiving the request for the salt data from the information handling system, generating the salt data;

providing the salt data to the information handling system;

receiving encrypted data from the information handling system;

decrypting the encrypted data to determine decrypted data;

determining that the decrypted data includes the salt data;

in response to the determining that the decrypted data includes the salt data, determining, from the decrypted data, a hash value of at least a portion of an application of the information handling system;

determining that a data structure includes the hash value; and

in response to the determining that the data structure includes the hash value;

receiving information from the application; and

performing an action based at least on the information from the application.

9. The method of claim 8,

wherein the data structure stores a plurality of hash values that includes the hash value;

and

wherein the determining that the data structure includes the hash value includes comparing the hash value with one or more of the plurality of hash values until the hash value is matched to one of the plurality of hash values.

10. The method of claim 8, further comprising:

executing the instructions.

11. The method of claim 8, wherein the salt data includes at least one of a random number and a pseudo-random number.

12. The method of claim 8, wherein the decrypting the encrypted data to determine the decrypted data includes utilizing a public encryption key that is associated with a private encryption key that was utilized to produce the encrypted data.

13. The method of claim 12, further comprising:

encrypting a session key with the public encryption key to produce an encrypted session key; and

providing the encrypted session key to the application.

14. The method of claim 13, further comprising:

communicating, utilizing the session key, information with the application.

15. A device, comprising:

at least one processor; and

a memory medium, coupled to the at least one processor, that stores first instructions executable by the at least one processor, which when executed by the at least one processor, cause the device to;

receive, from an information handling system, a request for salt data;

in response to receiving the request for the salt data from the information handling system, generate the salt data;

provide the salt data to the information handling system;

receive encrypted data from the information handling system;

decrypt the encrypted data to determine decrypted data;

determine that the decrypted data includes the salt data;

in response to determining that the data structure includes the hash value;

receive information from the application; and

perform an action based at least on the information from the application.

16. The device of claim 15, wherein the device includes a docking station.

17. The device of claim 15,

wherein the data structure stores a plurality of hash values that includes the hash value;
