Abstract(in English) We are considering and proposing a shared attribute certification scheme with the aim of achieving user's privacy protection, in which authorities distribute and manage the user's privacy information by secret sharing scheme. In previous studies, we defined the notions of, as functions of the scheme, preventing illegal use of service and protecting the user's privacy . And we showed that can construct the scheme which has the two functions by combining some generic security techniques such as encryption schemes and digital signature schemes. In this paper, we propose the scheme which is more convenient and secure for user than the previous one.
