In this paper we propose two public key BE schemes that have efficient complexity measures. The first scheme, called the PBE-PI scheme, has O(r) header size, O(1) public keys and O(log N) private keys per user, where r is the number of revoked users. This is the first public key BE scheme that has both public and private keys under O(log N) while the header(More)
