摘要
提出了一种可验证的图像秘密共享方案。由于秘密份额由参与者自己选取,该方案可防止原始图像持有者和参与者的欺诈;不需要安全信道,降低了系统代价;影子图像小于原始图像,且参与者的秘密份额可以重用。在不可能存在安全信道的系统中该方案可以得到广泛应用。
This paper proposed a verifiable secret image sharing scheme. The new scheme could identify the cheaters no matter if she/he was the dealer or the participant because each participant chooses her/his own shadow by her/himself; the new system didn't need a security channel and the cost of the system could be lowered ; the size of the shadow image was smaller than the secret image ; the new scheme was also a multi-use scheme. The properties are useful in the system which exists a security channel impossibly.
