Abstract
A digital archive for storing encrypted content includes a header section and a body. The header section includes real headers, wherein at least a portion of each real headers is encrypted, and fake headers, wherein each of the fake headers is filled with cryptographically random bytes, wherein the fake headers are substantially more than the real headers. The body includes real contents, wherein at least a portion of each real content is encrypted, and fake contents in the rest of the body, wherein the fake content contains additional cryptographically random bytes, wherein the amount of the fake content is substantially greater than the amount of the real contents, wherein each of the real headers refers to a corresponding real content in the body and contains decryption information for the corresponding real content.
