摘要：

提出了一种与传统的秘密共享方法不同的新型的秘密共享方法，该方法是基于二进制秘密序列的位运算的秘密共享方法。秘密包括但不限于密码、消息等，秘密序列包括但不限于密码序列、消息序列等，将采用非M序列法则法形成的非M序列作为其秘密共享的子秘密序列M’的构成元素。提出了基于二进制序列的秘密共享的子秘密生成方法及对应的秘密恢复方法，该方法具有可行性与实效性。

Abstract:

A novel secret sharing method was proposed based on binary sequence,which was quite different from the traditional secret sharing method.This secret sharing method was based on binary secret sequence using bit operations.The secret here included but not limited to key,message,etc,meanwhile the secret sequence included but not limited to key sequence,message sequence and so on.And two new concepts which were called non-M sequence and non-M sequence rule method were defined.By using the non-M sequence rule method,the elements of sub-secret sequence M' of secret sharing were computed.The method for generating sub-secrets and the method for recovering secret was proposed based on binary sequence.The method was practical and effective.

Key words: secret sharing, binary sequence, non-M sequence, threshold scheme, secret recovery, information security
