Abstract
Techniques for multiple message retrieval for secure electronic communication are described. The techniques, for instance, utilize a server and computing devices employing a private information retrieval scheme to allow a receiving device to locate multiple electronic communications on a server, request delivery of the multiple electronic communications without the server being aware of which electronic communication are requested, and receive the electronic communications without the server being aware of which electronic communications were sent. For example, the server may utilize an efficient electronic communication storage structure for storing and retrieving multiple electronic communications.
