基于Hash函数的秘密共享方案设计

Hash function based secret sharing scheme designs

Chi Sing Chum, Xiaowen Zhang

摘要:

秘密共享方案通过将秘密分配给多个参与者来保护秘密。利用散列函数和羊群散列技术,我们首先建立了一个完美的理想的(t+1,n)门限方案,然后将其推广到任何一般访问结构的方案。如有必要,可将这些计划进一步设置为主动或可核查。由于哈希函数的快速计算,秘密的建立和恢复是有效的。该方案是灵活的,因为使用现有的哈希函数。

英文摘要:

Secret sharing schemes create an effective method to safeguard a secret by dividing it among several participants. By using hash functions and the herding hashes technique, we first set up a (t+1, n) threshold scheme which is perfect and ideal, and then extend it to schemes for any general access structure. The schemes can be further set up as proactive or verifiable if necessary. The setup and recovery of the secret is efficient due to the fast calculation of the hash function. The proposed scheme is flexible because of the use of existing hash functions.
