Abstract

See full text

Techniques are provided for processing data. Connections having different security properties are stored, wherein each of the connections allows applications at the client computer to access data sources at a server computer. A request is received from an application to access a data source, wherein the request has associated security properties. In response to the client computer requesting establishment of a connection on behalf of the application, it is determined whether there is a stored connection that used a same set of security properties as are associated with the request from the application and that connected to the data source that the application requests access to. In response to determining that there is a stored connection that used the same set of security properties and that connected to the data source, the connection and an associated client encryption seed, client encryption token, server encryption seed, and server encryption token are re-used. In response to determining that there is not a connection that used the same set of security properties and that connected to the data source, a new client connection key, client encryption seed, client encryption token, sever connection key, server encryption seed, and server encryption token are generated.
