New solutions in encryption methods

Our company develop modern, trustworthy, patented cryptosystems designed to solve cyber security challenges of the 21st century.

Encryption

Encryption is a digital form of cryptography, which uses mathematical algorithms to scramble messages, leaving only individuals who possess the sender’s cipher and key able to decode the message.

There are two main methods of encryption: symmetric encryption, which involves securing data with a single private key, and public key encryption, which uses a combination of public and private keys.

Symmetric-key encryption can use either stream ciphers or block ciphers.

Stream ciphers encrypt the digits (typically bits or bytes), or letters (in substitution ciphers) of a message one at a time.

Block ciphers take a number of bytes and encrypt them as a single unit, padding the plaintext so that it is a multiple of the block size. The Advanced Encryption Standard (AES) algorithm, approved by NIST in December 2001, uses 128-bit blocks.

A stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream (keystream). In a stream cipher, each plaintext digit is encrypted one at a time with the corresponding digit of the keystream, to give a digit of the ciphertext stream.

In cryptography, a block cipher is a deterministic algorithm operating on fixed-length groups of bits, called blocks. It uses an unvarying transformation, that is, it uses a symmetric key. They are specified elementary components in the design of many cryptographic protocols and are widely used to implement the encryption of large amounts of data, including data exchange protocols.

Stream ciphers vs Block ciphers

Processing or encoding of plan text is done bit by bit. The block size here is half bite or one bite	Processing or encoding of the plain text is done as a fixed length block one by one. A block for example could be 128, 192 or 256 bits in size
A different pseudo-random sequence is used to encrypt	The same key is used to encrypt each of the blocks
Block are processed one by one as in a chain	A Pad is added to extend the length of the short blocks
High speed and low hardware complexity	Uses Symmetric Encryption and it is NOT used in asymmetric encryption
Key is often combined with an initialization vector	Confusion factor: the key to the ciphertext relationship could be really very complicated
Statistically random ciphertext if properly designed	Most block ciphers are based on Feistel cipher or substitution-permutation network in structure
Depends on a large key and large linear complexity	Looks more like an extremely large substitution
Usually very simple and much faster	Usually more complex and slower operation
Examples of stream cipher are: FISH, RC4, ISAAC, SEAL, SNOW, Vernam cipher, etc	Examples of block cipher are: Lucifer / DES, IDEA, RC5, Blowfish, AES, etc

OUR SOLUTION

Our stream cipher solution

The subject of the invention is a symmetric key stream cipher cryptographic method for encrypting plaintexts and decrypting ciphertexts during which process a text to be encrypted or an encrypted text is scanned with an input/output data buffer, a pseudo random number is created with a pseudo random number generator with a seed, a key automaton is used for encryption and/or decryption.

It is characterized in that the procedure involves the method whereby using the characters of the text scanned by the input/output data buffer and the pseudo random number generated by the pseudo random number generator, an element of the key automaton’s transition matrix is directly reached from the input/output data buffer; the procedure is then repeated. A symmetric key stream cipher cryptographic device is also the subject of the invention.
