A Complete Asymmetric Public-Key Traitor Tracing Scheme
一种完整的非对称公钥叛逆者追踪方案

Based on oblivious polynomial evaluation, this paper presents a new asymmetric public-key traitor tracing scheme. Compared with the previous schemes, this proposed scheme can accurately determine a or all traitor(s) from an illegal decoder by full black-box tracing when the number of traitors participating conspiracy is not larger than the defined number; and revoke unlimited traitors by means of the way of updating secret key. Moreover, this proposed scheme greatly decreases the computational cost of tracing a traitor and has a higher transmission efficiency compared with those of available.
