Secure and Efficient Construction of Broadcast Encryption with Dealership
Broadcast encryption with dealership (BED) has been proposed to achieve more innovative and scalable business models for broadcast services. It has an extensive application future. However, designing secure BED is a challenging task. The only known BED construction so far is by Gritti et al. We aim to raise the profile of BED primitives which has not received much attention despite of its impor...
متن کاملBroadcast Encryption
We introduce new theoretical measures for the qualitative and quantitative assessment of encryption schemes designed for broadcast transmissions. The goal is to allow a central broadcast site to broadcast secure transmissions to an arbitrary set of recipients while minimizing key management related transmissions. We present several schemes that allow a center to broadcast a secret to any subset...
متن کاملBroadcast Encryption
Our system consists of a center and a set, U of n users. The center provides keys to the users when they join the system. Later on, the center wants to broadcast an encrypted message (such as the password to view “Matrix”) which can be deciphered only by a dynamically changing privileged subset of users, T , i.e., the non-privileged users should not be able to learn the message. To achieve this...
متن کاملBroadcast Encryption
Broadcast encryption is an interesting application of cryptography which allows one to broadcast a secret to a changing group of intended recipients in such a way that no one outside this group can view the secret. Interest in using broadcast encryption techniques has grown considerably in recent years and such techniques have been integrated in many applications and technologies such as virtua...
متن کاملLong-Lived Broadcast Encryption
In a broadcast encryption scheme, digital content is encrypted to ensure that only privileged users can recover the content from the encrypted broadcast. Key material is usually held in a “tamperresistant,” replaceable, smartcard. A coalition of users may attack such a system by breaking their smartcards open, extracting the keys, and building “pirate decoders” based on the decryption keys they...
