In this paper we introduce the notion of identity based encryption with wildcards, or WIBE for short. This allows the encryption of messages to multiple parties with common fields in their identity strings, for example email groups in a corporate hierarchy. We propose a full security notion and give efficient implementations meeting this notion in the standard model and in the random oracle model
