The average transmission overhead for broadcast encryption
We consider broadcast encryption schemes wherein a center needs to broadcast a secret message to a privileged set of receivers. We prescribe a probability distribution P on the privileged set. In this setting, the transmission overhead can be viewed as a random variable over P and we define its expected value as the average transmission overhead (or ato). Given P, the Shannon’s entropy function...
متن کاملLow Overhead Broadcast Encryption from Multilinear Maps
We use multilinear maps to provide a solution to the long-standing problem of public-key broadcast encryption where all parameters in the system are small. In our constructions, ciphertext overhead, private key size, and public key size are all poly-logarithmic in the total number of users. The systems are fully collusion-resistant against any number of colluders. All our systems are based on a...
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...
