System and method for field-level encryption using multiple groups of data encryption keys

A system comprising:

• one or more processors;
• and
• one or more memories storing processor-executable instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• receiving multi-device keys for encrypting a message, wherein the multi-device keys include (1) a first data encryption key (DEK) from among a first group of DEKs that permits a first consuming device to access a first field of the message and (2) a second DEK from among a second group of DEKs that permits a second consuming device to access a second field of the message;
• encrypting the message by encrypting (1) the first field using the first DEK and (2) the second field using the second DEK;
• and
• transmitting the encrypted message to a stream processing platform to permit (1) the first consuming device to decrypt the first field and (2) the second consuming device to decrypt the second field.

One or more non-transitory computer-readable media storing processor-executable instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• receiving multi-device keys for encrypting a message, wherein the multi-device keys include (1) a first data encryption key (DEK) from among a first group of DEKs that permits a first consuming device to access a first field of the message and (2) a second DEK from among a second group of DEKs that permits a second consuming device to access a second field of the message;
• encrypting the message by encrypting (1) the first field using the first DEK and (2) the second field using the second DEK;
• and
• transmitting the encrypted message to a stream processing platform to permit (1) the first consuming device to decrypt the first field and (2) the second consuming device to decrypt the second field.
