Anonymous broadcast encryption with an untrusted gateway
We propose a verifiable and anonymous broadcast encryption scheme, where an 'untrusted' gateway can verify incoming communication flows to ensure only the intended anonymous receivers in the target domain can receive them. This scenario is interesting while the privacy of receivers should be considered. The difficulty in this setting is how to achieve both confidentiality of the message and ano...
متن کاملOutsider-Anonymous Broadcast Encryption with Sublinear Ciphertexts
In the standard setting of broadcast encryption, information about the receivers is transmitted as part of the ciphertext. In several broadcast scenarios, however, the identities of the users authorized to access the content are often as sensitive as the content itself. In this paper, we propose the first broadcast encryption scheme with sublinear ciphertexts to attain meaningful guarantees of ...
متن کاملAnonymous Identity-Based Broadcast Encryption with Revocation for File Sharing
Traditionally, a ciphertext from an identity-based broadcast encryption can be distributed to a group of receivers whose identities are included in the ciphertext. Once the ciphertext has been created, it is not possible to remove any intended receivers from it without conducting decryption. In this paper, we consider an interesting question: how to remove target designated receivers from a cip...
متن کاملEnhanced Outsider-anonymous Broadcast Encryption with Subset Difference Revocation
This paper puts forward an efficient broadcast encryption in public key setting employing ternary tree subset difference method for revocation. It provides outsider anonymity disabling the revoked users from getting any information of message and concealing the set of subscribed users from the revoked users. Our approach utilizes composite order bilinear group setting and exhibits significant i...
متن کاملAdaptively Anonymous Public-Key Broadcast Encryption Scheme without Random Oracle
Anonymous is one of the most important security properties for kinds of Internet applications. In this paper, we consider the privacy-preserving problem in the context of public key broadcast encryption. We provide a new security definition for anonymous public key broadcast encryption, and construct a new scheme. To achieve anonymous, we blind the ciphertexts using the random factors. Moreover...
