Over-the-air encryption

Over-the-air encryption is an optional mechanism of MINT core protocol. Over-the-air encryption mechanism is an extremely reliable way to protect all data transmitted by the radio from hacking and sniffing.

Below is a description of InfiNet Wireless proprietary over-the-air encryption mechanisms.

In the base of InfiNet Wireless Encryption Algorithm (hereionafter, “algorithm”) lies an open-source version of RC4 known as “ArcFour”.

Advantages of InfNet Wireless over-the-air encryption algorithm:

• WEP algorithm idea is used, but, compared to WEP, 16 bytes (128 bits) keys are used
• Compared to WEP algorithm where only four fixed transport keys are used, InfiNet Wireless algorithm uses randomly generated and regularly renewed transport keys
• For every data packet a new initialization vector is used
• ArcFour algorithm was also modified to ensure abruptness of the pseudo-random sequence
• Also, being simple by nature, the algorithm does not occupy too much of the unit’s processing power.
