If such a collusion happens, at least one member of the latter collusion will be detected. Several solutions have already been proposed in the literature, but the most important problem to solve remains having a very good ciphertext/plaintext rate. At Eurocrypt ’02, Kiayias and Yung proposed the first scheme with such a constant rate, but still not optimal. In this paper, granted bilinear maps, we manage to improve it, and get an “al
