Abstract:
1. A non-transitory computer readable medium comprising a digital archive for storing encrypted content, the digital archive comprising: a header section, including: a first number of real headers, wherein at least a portion of each of the first number of real headers is encrypted; and a second number of fake headers, wherein each of the second number of fake headers is filled with cryptographically random bytes, wherein the second number is substantially greater than the first number; and a body, including: the first number of real content, wherein at least a portion of each of the first number of real content is encrypted, wherein each of the real headers contains a start location of the corresponding real content in the body and the start location is a modulus of a size of the digital archive; and fake content 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 first number of real headers refers to a corresponding one of the first number of real content in the body and contains decryption information for the corresponding one of the first number of real contents, wherein each of the real headers contains a header salt for decrypting the real header.
