Abstract: An extended coloured k out of n secret sharing scheme for general access structures is proposed, and a new method to construct coloured k out of k secret sharing schemes is given, with a class of coloured k out of n secret sharing schemes constructed by block design. It is shown that there exists a coloured k out of n secret sharing scheme for any parameter k and n such than kn.

Key words: block design, secret share, colour visual secret sharing schemes
