the wlan security scheme of the third party authentication based on symmetric cryptosystem 基于對稱密碼體制的第三方認證的無線局域網(wǎng)安全方案研究
by combination use of the symmetric cryptosystem and threshold cryptosystem, this paper proposes a practical scheme of secure distributed storage, which aims to guarantee that the process of storing the information is correct even when some of the servers fail, while considering the privacy requirement of the system, and don't storing the encryption / decryption key in a single device, either held by the user or by the servers 摘要結(jié)合對稱加密技術(shù)和門限加密技術(shù),提出了一種適用于分布式數(shù)據(jù)存儲需要的有效的系統(tǒng)機密性保護方案,其中對稱加密技術(shù)用于對所存儲的文件進行加密,分布式門限加密技術(shù)則對對稱加密方案中所用的密鑰進行保護,可在不帶來密鑰存儲問題情況下滿足惡意環(huán)境中分布式數(shù)據(jù)存儲系統(tǒng)的機密性要求。
