Abstract
To extend a sign on session among applications, an inter-application workflow request can be initiated from a first to a second application. The workflow request can identify one or more memory locations in a shared memory for secure data transfer between the applications. The first application can then monitor the memory locations for the presence of a public key stored in shared memory by the second application in response to the workflow request. Once the public key is present in the shared memory, the first application can retrieve and use it to encrypt an access interval key. The encrypted access interval key can then be stored in the shared memory for retrieval by the second application. The access interval key is associated with a sign on session of the first application, and the second application can retrieve and decrypt it to extend the sign on session to the second application.
