In the context of STAR Transport, Asynchronous means that a specific thread of execution sending a message does NOT wait for an application level reply before continuing on to other processing or completing execution.

For example, when a STAR message is sent asynchronously over HTTP, the thread of   execution waits only for an HTTP reply or HTTP error before continuing, it does not wait for a transport level Acknowledgment or a business level Acknowledgment before continuing; the environment executing the thread may expect a Transport level and or Business level reply to be received later as in inbound message in a completely separate and unrelated HTTP session.

Digital Certificate

A digital certificate is an electronic attachment issued by a certification authority containing credentials such as “name, a serial number, expiration dates, a copy of the certificate holder's public key (used for encrypting messages and digital signatures), and the digital signature of the certificate-issuing authority so that a recipient can verify that the certificate is real.” ( )

Digital Signatures

A digital signature (not to be confused with a digital certificate) is an electronic signature that can be used to authenticate the identity of the signer of a document, and to ensure that the original content of the message is unchanged. The ability to prove that an original signed message arrived infers that the sender cannot easily repudiate it later.
