Abstract:
A method of controlling access to a message queue of a receiver in a message queuing system with asynchronous message delivery, comprising the steps of:registering with a trusted server of the message queuing system a public key of a user of the message queuing system associated with a security identification (SID) of the user for identifying the user, the trusted server being a separate entity from the receiver; forming a digital signature for a message generated by an application run by the user using a private key associated with the public key of the user; transmitting to the receiver a message packet including the message, the public key of the user, and the digital signature; verifying, by the receiver, the signature transmitted with the message using the received public key; querying, by the receiver, the trusted server to obtain the SID associated with the public key transmitted with the message; and determining whether to allow the message to be placed in a message queue of the receiver based on the obtained SID.
