基于有限域的音频秘密分享方案研究

Secret Sharing Scheme From Audio Perspective Over Finite Fields

提出一种基于有限域的音频秘密分享方案,抛弃传统秘密分享中使用拉格朗日插值多项式的方法,极大提高音频数据的分享效率.测试结果表明该方案能完全实现(k,n)门限的设置,各个份额数据具有清晰的听觉意义和完备性,并能对秘密音频数据进行完全精确的恢复.

A new secret sharing scheme of audio based on coding which greatly improved the efficiency of sharing is proposed.Different from traditional secret sharing schemes,the scheme discards the method of Lagrange interpolation polynomial.The simulation results show that the new scheme realizes（k,n） threshold settings absolutely and can recover the audio secret data accurately,and all the secret sharing data have clear audition significance and perfection.
