• 論文の詳細を見る

• The function of a message authentication code(MAC)is to verify the validity of a whole message. The disadvantage of usual MACs is that a receiver can not check its validity until the receipt of a message is finished. Hence, usual MACs are not suitable for verifying a large amount of data such as video and audio(called stream). In this letter, we propose a MAC such that the validity of a stream can be consecutively verified without waiting for the end of the reception. In addition, we show its implementations : one is based on practical hash functions, and the other is based on universal hash functions.
