Abstract
The present invention relates to methods and systems for preventing race conditions in secure token conversations. The method includes generating a message from a client application to a server application, determining that a first secure conversation token (SCT) exists, and using the first SCT to encrypt the message. The method further includes sending the encrypted message to the server, receiving an indication that the first SCT has expired, and initiating an SCT renew request. The method includes storing the first SCT, receiving a second SCT in response to the SCT renew request, and storing the second SCT in addition to the first SCT. The method further includes retrieving an encrypted message, determining that the encrypted message has been encrypted using the first SCT, in response to the determination, using the first SCT to decrypt the message, and generating a response from the server to the client.
