Is DESpro encryption really secure?
Yes, it is! The DESpro encryption of the dLAN® devices provides your network with reliable protection from unwanted access. There are two conceivable types of attack that are defeated by the DESpro encryption. A brute force attack could be launched in order to find the key for decrypting the data. In this type of attack, all possible letter and number combinations in the chip are tested. However, given the variety of the keys and a maximum transfer rate between the PC and chip of 100 Mbps (Ethernet interface), a brute force attack of this kind would, on average, take 4,500 years to succeed. Another type of attack would be to intercept encrypted raw data. The encrypted raw data could provide clues to the key, thus allowing access to the unencrypted raw data. In dLAN® technology, however, it is not possible to intercept the encrypted raw data from the electrical wiring, as the chip does not send encrypted data directly to the network interface. The signal is both encrypted and immediatel
