Encryption / Ethcryptor-IP Encryptor-10/100/1000 Mbps

Security, a critical feature in today’s networks, enables secure transactions for any organization commercial or defense to communicate between 2 or more independent transacting parties. Network security also enables sharing data across different global locations. To address such issues in today’s IP world Dexcel has designed Network Encryptor-Decryptor (Ethcryptor).
EthCryptor provides a means to secure the network communication by encrypting the IP packet. It helps protect sensitive data against attack from the network. It is completely transparent to the network and domain.


EthCryptor supports two ports,plain and cipher.Data to be encrypted is fed to the plain port and encrypted data is available at the Cipher port. The encrypted data is now secured to be transmitted to any network and domain. This information of encrypted data can only be decrypted by Dexcel’s Ethcryptor at the other end which makes the whole cycle of communication with Encryption and Decryption safe and secure. Decryption of the data extraction is done in the same way as of encryption by feeding the data into the cipher port and output from the plain port.

EthCryptor also supports a special feature that would alert if there is any intrusion or ping to the plain or cipher port from any non configured sources (ip address).

The filtering algorithm implemented in the product makes sure that only TCP/UDP data gets encrypted/decrypted. Any other IP packets which are used for discovery of the network are simply sent from plain to cipher and vice-versa as pass through like a pipe. With this feature only the packets which contain data or configured IP information are encrypted and the rest are just passed as it is.

EthCryptor supports two encryption modes: Transport and Tunnel. Transport mode encrypts only the data portion (payload) of each Ethernet packet, but leaves the ethernet header untouched. The more secure Tunnel mode encrypts both the header and the payload.

Ethcryptor is designed to support multiple encryption standard algorithms like DES, 3-DES, AES. It is also designed to support custom algorithms which can be implemented either in the software using C/C++ language or in the hardware using VHDL/Verilog

Software and Hardware logic works together to bring Ethcryptor in action. Ethcryptor’s hardware can be designed in multiple variants like ASIC, FPGA or ASIC + FPGA units.

1. ASIC only In this version, encryption engine is designed in the software typically written in C language.

2. FPGA: In this version, encryption engine is designed in VHDL/Verilog targeted for a FPGA.These designs are
implemented using a soft processor. In this case the soft processor and the encryption engine both sit on the same FPGA.

3. ASIC + FPGA: In this version encryption engine sits on a separate FPGA while the processor is part of the ASIC.
