A Review on Fine-Grained Approach for Unified Group Email Broadcasting Using Identity Based Encryption

  R. L. Bombale,  Prof. S.M.Rokade

Previous techniques of certificate verification such as, pretty good privacy protocol and identity-based encryption (IBE) are unsuitable for updating the ciphertexts and keys. Both techniques were used for emailing security purpose. But these techniques preserve the security of cloud email but their performance is less efficient due the linear size with the number of receivers. Also they required certificate verification of the receiver from security point of view. A proxy re-encryption technique based on Identity-based broadcast encryption i.e. CIBPRE scheme. Re-encryption key associated with the condition such that only matching ciphertext can be re-encrypted. It allows the original sender to enforce access control over his remote ciphertext in fine-grained manner. In this paper we are contributing ourselves for user group creation for sharing data with them at same time by which encryption & re-encryption time can be decreases as compared to previous system.

Keywords- Proxy re-encryption, cloud storage, identity-based encryption, broadcast encryption
