ESS polls CSS (ESS calls /spi/v1/objects, only applied to the object with data):
After ESS polls all data, verify the data. If data is not successfully verified, change destination status to error with messages
ESS creates object and sends to CSS:
When "create/update an object" ESS API is called, it should do:
generate a pair of private/public key
use the private key to sign the data, so that a data signature is generated
set public key and signature in metadata
call CSS SPI PUT /spi/v1/objects to save metadata in CSS DB
call CSS SPI PUT /spi/v1/objects/..../data to upload data. Then CSS backend function handlePutData() needs to get the metadata from CSS DB and verify the data
