Owl Secure Acknowledgement Engine (OSAE)

The Owl Secure Acknowledgement Engine OSAE is an appliance with attendant software used with Owl secure one-way transfer platforms. Based on the Owl US Patent #7,675,867, OSAE provides the user-sender with explicit confirmation that information transferred across an Owl one-way system has, in fact, been received at the user destination. The acknowledgement and the path it takes are completely independent of and discrete from the unidirectional data transfer path. Absolute assurance of one-way transfer is maintained.

Acknowledgement flow using OSAE
A broad range of acknowledgement schemes is available.
An example -- for process-oriented data transfers, user source registers possible return codes with OSAE software. This application calculates and stores mathematical values for each of the return codes. With successful transfer, the user destination creates an acknowledgement packet, returning this value to the Owl transfer platform as UDP datagrams. OSAE hashes these packets. This value is sent to the OSAE appliance for re-hashing of the mathematical value. OSAE reads the hash packet, performs another hash operation, and sends the new hash packet to OSAE software. It evaluates the received hash value and compares it to the registered return codes, responding to the user-sender with the appropriate return code match.

File transfer-oriented acknowledgements may be configured differently. In lieu of acknowledgements compared to return codes, the user destination may generate an ACK packet that will contain specific information returned to the user-sender, such as timestamps, retransmit requests, etc.
