I am a one person company (OPC) that does research in both cryptography and cryptanalysis with the aim to create new products and/ or services.

## 3D cryptography.

**We propose a new method to encrypt, transmit and decrypt data in three-dimensions between two smartphones. **This technique consists of three distinct algorithms here called encryption, transmission and decryption.

The first algorithm transforms any alphanumeric string into a multicolored three-dimensional figure. The second algorithm converts the given string into a sequence of binary bits. The third algorithm transforms the respective binary sequence into the original string. We assume that the transmitter first types the message and then sees a three-dimensional representation of it, while the receiver first sees a three-dimensional figure and then reads the original message.

Practical implementation of this system was done using the program *Mathematica* and the size of the code is small. **Since all three algorithms can be executed relatively fast, we present an outline for a client-server architecture and an application. **
