| Abstract(in English) | Identity-based matchmaking encryption (IB-ME) is an advanced encryption system that enables a sender and a receiver to specify each of identity. However, identity-based matchmaking encryption (IB-ME) requires an authority called a key generation center (KGC) to generate keys for all users, which is computationally expensive. In this paper, we propose hierarchical identity-based matchmaking encryption (HIB-ME) that can reduce the burden of the (single) KGC, such as key generation for all users. Specifically, we define the notion and its required security of HIB-ME and give its generic construction. Furthermore, we show how to upgrade a chosen plaintext secure HIB-ME scheme into a chosen ciphertext secure one. |
