Abstract

Systems and methods for creating fingerprints for encryption devices are described herein. In various embodiments, the system includes an encryption device operatively connected to a device management system. According to particular embodiments, the device management system: 1) receives a first payload from the encryption device, the first payload including data in a particular format; 2) creates a fingerprint for the encryption device, the fingerprint including a section format for each of one or more distinct sections of the particular format; 3) storing a record of the fingerprint for the encryption device and the unique identifier at the at least one database; and 4) comparing a format of each subsequent payload received from the encryption device to the fingerprint for the device to determine whether the device has been compromised.

parsing the particular format of the first payload into the one or more distinct sections of the particular format;

determining the section format of each of the one or more distinct sections;

creating a record of the section format of each of the one or more distinct sections in the particular order; and

comparing a format of each subsequent payload received from the device to the fingerprint for the device to determine whether the device has been compromised.

2. The computer system of claim 1 , wherein the at least one processor is further configured for, upon determining that the device has been compromised, changing a state of the device to indicate the device is compromised.

3. The computer system of claim 2 , wherein the at least one processor is further configured for only decrypting payloads of devices with states indicating they have not been compromised.

4. The computer system of claim 1 , wherein comparing the format of each subsequent payload received from the device to the fingerprint for the device to determine whether the device has been compromised comprises:

receiving a second payload from the device, the second payload comprising second data in a second particular format and a second device indicator, the second device indicator comprising a second unique identifier used for identifying the device;

retrieving the fingerprint from the at least one database based on the second device indicator; and

comparing the second particular format to the fingerprint to determine whether the device has been compromised.

5. The computer system of claim 4 , wherein comparing the second particular format to the fingerprint to determine whether the device has been compromised comprises comparing the second format of each of one or more distinct sections of the second particular format to the section format for each of one or more distinct sections of the fingerprint.

6. The computer system of claim 5 , wherein the at least one processor is further configured for, upon determining that the device has been compromised, transmitting a message to a user indicating that the device has been compromised.

7. The computer system of claim 6 , wherein the at least one processor is further configured for, upon determining that the device has been compromised, disregarding the second payload without decrypting any data.

8. A computer system for creating a fingerprint for a device, the computer system comprising the device operatively connected to a device management system, the device management system comprising at least one processor operatively coupled to at least one database, the at least one processor configured for:

receiving payloads from a particular device, each payload comprising encrypted and unencrypted data in a format;

the first payload from a particular device comprising a device indicator comprising a unique identifier used for identifying the device and an indication of a version of firmware running on the device;

creating the fingerprint for the device, the fingerprint comprising a section format for each of one or more distinct sections of the particular format in a particular order and the indication of the version of the firmware running on the device, creating the fingerprint for the device comprising:

parsing the particular format of the first payload into the one or more distinct sections of the particular format;

determining the section format of each of the one or more distinct sections; and

creating a record of the section format of each of the one or more distinct sections in the particular order;

comparing the format of each payload from the particular device to the fingerprint associated with the particular device; and

upon determining that the format of a particular payload of the payloads received from the particular device does not match the fingerprint associated with the particular device, declining to decrypt the encrypted data of the particular payload and transmitting a notification of declining to decrypt the encrypted data to a user computing system associated with a user.

9. The computer system of claim 8 , wherein the at least one processor is further configured for, upon determining that the format of the particular payload of the payloads received from the particular device does not match the fingerprint associated with the particular device, changing a status associated with the particular device from active to tampered.

10. The computer system of claim 8 , wherein each payload from the particular device includes one or more segments of data in a particular order.

11. The computer system of claim 10 , wherein each of the one or more segments of data included in the payload from the particular device is in a particular format.

12. The computer system of claim 11 , wherein the particular format for a particular segment of the one or more segments is a character format.

13. The computer system of claim 12 , wherein the particular format for a second particular segment of the one or more segments is a hexadecimal format.

14. The computer system of claim 8 , wherein the at least one processor is further configured for:

receiving payloads from a second particular device, each payload comprising encrypted and unencrypted data in a second format;

comparing the second format of each payload from the second particular device to a second fingerprint associated with the second particular device; and

upon determining that the format of a second particular payload of the payloads received from the second particular device does not match the second fingerprint associated with the second particular device, declining to decrypt the encrypted data of the second particular payload and transmitting a notification of declining to decrypt the encrypted data to a second computing system associated with a second user.

15. The computer system of claim 14 , wherein the fingerprint and the second fingerprint are not the same fingerprint.

16. A computer-implemented method for creating a fingerprint for a device, the method comprising:

providing a device capable of encrypting data;

providing a computer system operatively coupled to the device, the computer system comprising:

a decrypting means for decrypting data received from the device;

a fingerprint creation means for creating a fingerprint associated with the device;

at least one database; and

at least one processor operatively coupled to the decrypting means, the fingerprint creation means, and the at least one database;

receiving, by the at least one processor, a first payload from the device, the first payload comprising data in a particular format, a device indicator comprising a unique identifier used for identifying the device, an indication of the version of the firmware running on the device, and encrypted data;

creating, by the fingerprint creation means, a fingerprint for the device, the fingerprint comprising a section format for each of one or more distinct sections of the particular format in a particular order and the indication of the version of the firmware running on the device;
