摘要:
Securely storing data includes encrypting the data using a random key to provide obfuscated data, scrambling the obfuscated data to provide scrambled obfuscated data, generating a scramble schema indicating how to unscramble the scrambled obfuscated data, encrypting the scrambled obfuscated data to provide encrypted scrambled obfuscated data, splitting the scramble schema, and distributing separate portions of the scramble schema and separate portions of the encrypted scrambled obfuscated data to separate entities. The data may be private key data. Securely storing data may also include concatenating the random key on to the obfuscated data prior to scrambling the obfuscated data, wherein the random key is scrambled together with the obfuscated data. Scrambling the obfuscated data may use a Fisher Yates Shuffle mechanism. Securely storing data may also include generating and distributing a symmetric authentication key that is used to authenticate a first entity to a second entity.
