According to Kerckhoff's Principle, a cryptosystem that works is one about which everything except for the key can be known, without jeopardizing its security. In other words, Security through obscurity isn't. If you want us to evaluate a new cipher, describe in detail how it works. Provide us with samples - plaintext+key+ciphertext, so we can test our understanding of how the system works. Then provide us with a dozen or so samples of plaintext+ciphertext, encrypted with the same key, so we can see if we can recover said key. If you don't trust your system sufficiently to offer it up to a known-plaintext challenge, you clearly don't trust it very much. |
