Abstract
One embodiment provides a system that facilitates integrated security and high availability. During operation, the system obtains a number of data elements from a data stream based on a number of coded fragments that a code word includes. The system determines one or more bit-level operations for the data elements in such a way that at least one of the one or more bit-level operations becomes eliminated from a process of erasure encoding. The system then obfuscates the data elements based on one or more bit-level operations. Subsequently, the system generates a code word of the erasure encoding from the obfuscated data elements based on the generator matrix. The code word comprises a plurality of coded fragments.
