Polymorphic one time pad matrix
The present invention provides a simple and efficient cipher and key generation and selection capability from a predetermined, randomly changing, fixed size matrix (N) of ciphers and keys resulting in a very high-order approximation (N r,c→∞ ) of a true One Time Pad for encryption solutions such as the CipherLoc Polymorphic Key Progression Algorithmic Cipher Engine. The ciphers are randomly selected from a pool of user supplied ciphers, FIPS 140-2 or other certified ciphers and the keys are produced from various methods for generating a key that includes reading a data stream from a network or a Cryptographic Pseudo Random Number Generator (CPRNG)/Pseudo Random Number Generator (PRNG) or a Predetermined Cryptographic Key Generator (PCKG) or any combination of all. Ciphers and generated keys are randomly paired and stored in a volatile matrix for use by an encryption solution. When used with the CipherLoc Polymorphic Key Progression Algorithmic (PKPA) Cipher Engine, the OTP Matrix is a method of accomplishing the generation of the key and the selection and association of a suitable cipher with that key, for each sub-message, such that not only key space and equivalent keys (isomorphs) become important, but, the number of keys are also important, thus increasing the effective size of the key space in each sub-message.
1. A method of encryption simulating a one time pad comprising the steps of:
a. independently applying and changing encryption algorithms by reconfigurable matrix blocks;
b. selecting pre-synchronized and configured encryption blocks for either a single character or block composite symbol; and
c. multiplexing the encryption stream from the matrix of configured encryption blocks to select the encryption output and combining the output by temporal concatenation;
d. wherein each of said matrix blocks in the matrix is independent of the other and each block has an independent Time To Live (TTL) which is maintained in a table corresponding to each block in the matrix such that when the TTL expires;
(I) a cell in the block is marked as expired;
(ii) the cell is reset with a new, randomly selected cipher @, key (k) and TTL;
(iii) start TTL clock where one is subtracted from the TTL of each cipher in the table for every transmitted block; and
(iv) the “expired” marker is removed from the cell.
2. The method according to claim 1 wherein said reconfigurable matrix blocks comprise at least one field programmable gate array chip.
3. The method according to claim 1 wherein each symbol, or block, uses a random row/column to select what block the encryption process will use.
4. The method according to claim 3 wherein if a block is being replaced or is marked as expired when selection occurs, the block is marked and if marked, the next block is selected as with a hash collision.
5. The method according to claim 4 wherein said reconfigurable matrix blocks are created using memory architecture.
