秘密共享是指在一组参与者之间分发秘密的方法。这也被称为秘密分裂。在这种情况下，每个参与者都被分配了一份秘密。个人共享不包含任何信息。只有当足够数量的股份或所有股份组合在一起时，才能重建秘密。秘密共享方案是密码学中的重要工具，被用作许多安全协议的构建块，例如用于多方计算的通用协议、拜占庭协议、门限密码学、访问控制、基于属性的加密和广义不经意传输。可视秘密共享，又称可视密码术，提供了一种非常强大的技术，可以将可视秘密分发到两个或更多个共享中。当共享被组合在一起时，原始的视觉秘密就可以被发现。作为第一部分，本文首先研究了多种秘密共享方案。其次，提出了两种基于格雷码和异或运算的秘密共享方案。格雷码被用来构造份额，异或运算被用来重构秘密。该方法既可作为密码算法使用，也可用于秘密共享和视觉秘密共享。
Secret sharing refers to method for distributing a secret among a group of participants. It is also known as secret splitting. In this, each of the participants is allocated a share of the secret. The individual share doesn't carry any information. The secret can be reconstructed only when a sufficient number or all of shares are combined together. Secret-sharing schemes are important tools in cryptography and they are used as building blocks in many secure protocols, e.g., general protocol for multiparty computation, Byzantine agreement, threshold cryptography, access control, attribute-based encryption, and generalized oblivious transfer. Visual secret sharing, aka Visual Cryptography, provides a very powerful technique by which visual secret can be distributed into two or more shares. When the shares are combined together, the original visual secret can be discovered. In this paper, as first part, many types of secret sharing schemes are examined. Secondly we proposed two variant of a secret sharing scheme using Gray code and XOR operation. The Gray code is used to construct the shares and the XOR operation is used to reconstruct the secret. The proposed method can be used as a cryptographic algorithm and also for secret sharing as well as visual secret sharing.
