SECURE MEMORY SHARING

A computer-implemented method includes, receiving, by a source node, a request from a destination node for data stored in a region of shared memory controlled by the source node. The data is encrypted in a local key of the source node. The method includes decrypting, by the source node, the locally encrypted data using the local key and encrypting, by the source node, the decrypted data using a first key for generating first encrypted data. The method also includes encrypting, by the source node, the first encrypted data using a second key for generating second encrypted data, and sending, by the source node, the second encrypted data to the destination node. A computer program product includes one or more computer readable storage media and program instructions collectively stored on the one or more computer readable storage media. The program instructions includes program instructions to perform the foregoing method.
