Identity-Based Broadcast Encryption Scheme Sample Clauses

Identity-Based Broadcast Encryption Scheme. This section gives an overview of a research in an identity-based broadcast encryption scheme as proposed by ▇▇, ▇▇▇▇, Ge, and ▇▇▇▇ (2005). In this scheme, an identity-based broadcast encryption is used to distribute a key over a network, so that each member can compute a specified key. Then a conventional private key cryptosystem such as data encryption standard (DES) can be used to encrypt subsequent messages. Their scheme consists of a center and a set of users U = {IDi | i = {1,…,n}), where IDi is a unique identifier of user i. Each user has a public/private key pair (Qi,Si). The broadcast encryption is as the following.
