Data consistency and integrity for one-way connected systems

A method, comprising:

• sending a first plurality of payloads via a communication channel having one-way connectivity, wherein each payload of the first plurality of payloads is in a container structure that includes a time stamp that is associated with the payload, and wherein the communication channel is network-based;
• transmitting, via the communication channel, independently of the first plurality of payloads, a unit manifest corresponding to each payload of the first plurality of payloads, wherein the unit manifest includes information associated with the first plurality of payloads, including, for each payload of the first plurality of payloads, information associated with the payload including a hash of the payload;
• and
• at predetermined periodic times, sending an aggregate manifest associated with a predefined time period, such that the predefined time period has a predefined duration that is longer than a duration that is associated with the unit manifest, wherein the aggregate manifest includes aggregate manifest information, and wherein the aggregate manifest information includes information from each payload transmitted via the communication channel during the predefined time period.

A processor-readable storage medium, having stored thereon processor-executable code that, upon execution by at least one processor, enables actions, comprising:

• obtaining a first plurality of artifacts via a communication channel having one-way connectivity, wherein each artifact of the first plurality of artifacts is received in a format that includes a time stamp that is associated with the artifact, and wherein the communication channel is network-based;
• ascertaining whether a unit manifest corresponding to a transaction associated with at least one artifact of the first plurality of artifacts has been received via the communication channel transmitted independently of the first plurality of artifacts;
• in response to ascertaining that the unit manifest has been received, wherein the unit manifest includes information associated with a second plurality of artifacts, including, for each artifact of the second plurality of artifacts, information associated with the artifact including a hash of the artifact, ascertaining whether the information associated with the second plurality of artifacts matches the corresponding artifacts;
• responsive to ascertaining that the information associated with second plurality of artifacts matches the corresponding artifacts, processing the corresponding artifacts;
• ascertaining, based on the time stamps associated with the first plurality of artifacts, whether an out-of-order processing has occurred;
• ascertaining whether an aggregate manifest associated with a predefined time period has been received, such that the predefined time period has a predefined duration that is longer than a duration that is associated with the unit manifest;
• and
• in response to ascertaining that the aggregate manifest has been received, ascertaining whether aggregate manifest information from the aggregate manifest matches artifacts from the predefined time period.
