Abstract: The cryptographic system and method for securing data from unauthorized access includes, in one embodiment, an iterative probabilistic cipher for converting plaintext into ciphertext comprising at least two components, a core and a flag. A corresponding key and the core and flag may be output in one or more data channels. For each round of encryption additional keys, cores and flags can be generated. Unless all keys, cores and flags are known, no recovery of the plaintext can be possible.
