Abstract
A secure data parser is provided that may be integrated into any suitable system for securely storing and communicating data. The secure data parser parses data and then splits the data into multiple portions that are stored or communicated distinctly. Encryption of the original data, the portions of data, or both may be employed for additional security. The secure data parser may be used to protect data in motion by splitting original data into portions of data, that may be communicated using multiple communications paths.
Claims22
A method for securing a data set in a distributed storage network, the method comprising:
- encrypting, using a hardware processor, the data set using an encryption key;
- generating at least two portions of data from the encrypted data set, wherein each of the at least two portions of data respectively contains a substantially random shuffling of a respective subset of the encrypted data set;
- generating encryption key information that is capable of being used to generate the encryption key, wherein the encryption key information is distributed among the at least two portions of data;
- and
- storing each of the at least two portions of data to separate storage locations of the distributed storage network.
