Encryption verification method and system based on chameleon hash

Abstract

The invention relates to the technical field of data encryption, in particular to an encryption verification method and system based on chameleon hash. According to the invention, only the initial encryption processing with small computing power is carried out on the data owning terminal, and the residual encryption work with large computing power is carried out on the block chain. The initial encryption of the data is executed on the data owning terminal, the data is endowed with certain security, and the pre-encrypted data with certain security is further encrypted on the open-source block chain, so that the security of the data can be fully ensured. In addition, according to the invention, the initial encryption processing with low requirement on the computing power is executed on the data owning terminal, and the re-encryption processing with high requirement on the computing power is executed on the block chain, so that the encryption speed can be improved by means of the computing power of the block chain. In conclusion, the security of the encrypted data and the encryption speed are ensured, so that the data encryption performance is improved. 本发明涉及数据加密技术领域，具体是涉及一种基于变色龙哈希的加密验证方法和系统。本发明只将算力较小的初加密处理放在数据拥有终端上进行，而将算力较大的剩余加密工作放在区块链上进行。在数据拥有终端上执行数据的初加密，赋予了数据一定的安全性，将具有一定安全性的预加密数据再在开源的区块链上进一步加密就能够充分保证数据的安全性。而且本发明将对算力要求低的初加密处理放在数据拥有终端上执行，而将对算力要求高的再加密处理放在区块链上执行，能够借助区块链的算力提升加密速度。综上所述，本发明既保证了加密数据的安全性又保证了加密速度，从而提升了数据加密性能。
