Managing payload decryption via fingerprints

A point to point encryption management computing system comprising at least one hardware processor operatively coupled to memory, the at least one hardware processor configured to:

• receive an initial payload from one or more devices, each initial payload comprising encrypted and unencrypted data in a format;
• parse each initial payload to extract a unique identifier;
• retrieve a unique identifier table from memory;
• compare each of the unique identifiers to the unique identifier table to determine whether each of the unique identifiers are included in the unique identifier table;
• upon determining that each of the unique identifiers are included in the unique identifier table, create a fingerprint associated with each unique identifier, wherein each fingerprint is created by:
• parsing the format of each initial payload into one or more distinct sections;
• determining a 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;
• and
• compare the format of each subsequent payload from the one or more devices to the fingerprint associated with the unique identifier for the one or more devices;
• and
• upon determining that the format of a particular payload of the subsequent payloads received from a particular device does not match the fingerprint associated with the unique identifier for the particular device, decline to decrypt any encrypted data of the particular payload and transmit a notification of declining to decrypt the encrypted data to a user computing system.

A computer-implemented method for managing payload decryption via a computing system operatively coupled to an encryption device, the method comprising:

• receiving, by at least one processor, a first payload from the encryption device, the first payload comprising data in a particular format, a unique identifier used for identifying the encryption device, and encrypted data;
• extracting the unique identifier from the first payload;
• comparing the unique identifier to a unique identifier table retrieved from memory to determine whether the unique identifier is included in the unique identifier table;
• upon determining that the unique identifier is included in the unique identifier table, creating, by a fingerprint creation means, a fingerprint for the encryption device, by:
• parsing the particular format into 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;
• storing a record of the fingerprint and the unique identifier in memory and changing a state of the encryption device to active by the at least one processor;
• comparing, by the at least one processor, a second particular format of a subsequent payload received from the encryption device to the fingerprint for the encryption device to determine whether the encryption device has been compromised;
• and
• upon determining that the encryption device has not been compromised, decrypting encrypted data of the subsequent payload.
