Wireline Performance Encryption Speeds for Ethernet Networks

Wireline Performance is Maintained Through the Use of RedCreek's CryptoCore™ Technology.

The RedCreek Ravlin 10 is a cost-effective network security solution that performs encryption and decryption with a throughput of the theoretical maximum of Ethernet (or "wire" speed). Network administrators use it to establish private communications within secure intranets (between corporate divisions, workgroups, branch offices, and individuals) or within secure extranets (between customers, suppliers, and strategic partners.) Its low cost allows organizations to establish security over private or public IP networks quickly and easily.

The Ravlin 10 provides data privacy using industry-standard 40-bit/56-bit DES and 168-bit Triple DES encryption. Authentication and access control are provided using DSS (Digital Signature Standard), Diffe-Hellman key exchange, X.509 v.3 digital certificates, and ISAKMP/Oakley key management. These security standards are part of the Internet Engineering Task Force (IETF) IP Security Standard (IPSec). The Ravlin 10 maintains the theoretical maximum of Ethernet (or "wire" speed) through the use of RedCreek CryptoCore™ technology.

The Ravlin 10 supports RavlinSoft Clients running on Windows® 95, Windows NT® 4.0, and Windows for Workgroups 3.11 systems, allowing remote communications over public and private networks. Organizations can also purchase enhanced firmware to allow strong RADIUS user authentication for standard remote software. Ravlin RADIUS Authentication provides interoperability with user authentication hardware tokens that have standard RADIUS interfaces. The Ravlin 10 firmware has all mandatory components of the Internet Engineering Task Force (IETF) IP Security Standard (IPSec) for enhanced network security.

IP Security Standard (IPSec)
IPSec is the most secure and comprehensive standard available today for encryption, authentication, key management, and anti-replay services.

IPSec protocol interoperability lets Ravlin products exchange keys and encrypted communications with all other IPSec-compliant products, so customers can use different IPSec vendors for multiple scenarios. RedCreek can provide a list of IPSec interoperability partners upon request.

The Ravlin 10 firmware supports the strongest suite of IPSec network security enforcement features available today. Using RavlinNodeManager, the Ravlin 10 firmware gives the network administrator or security manager a choice of several secure VPN operational modes.

ESP (Encapsulated Security Protocol) Tunnel Mode
ESP Tunnel mode provides the highest level of security between gateways. The original IP datagram is encapsulated in a new IP packet using a new IP address as the source/destination of the packet. ESP Tunnel mode uses 40-bit/56-bit DES or 168-bit Triple DES encryption.

ESP (Encapsulated Security Protocol) Transport Mode
In ESP Transport mode, only the payload of the original IP datagram is encrypted. Like ESP Tunnel mode, ESP Transport mode uses 40-bit/56-bit DES or 168-bit Triple DES. Ravlin 10 units also support Authentication Header (AH) Transport mode and Authentication Header (AH) Tunnel mode, which use strong authentication and anti-replay to secure IP datagrams without encrypting the data payload. ESP Transport mode uses hashing methods to ensure that the data stream is not modified.

Encrypt-in-Place (EIP) Mode
In EIP mode, only the payloads of IP datagrams are encrypted. Like ESP mode, EIP mode can use 40-bit/56-bit DES or 168-bit Triple DES. EIP mode is a RedCreek proprietary secure VPN technology. Although EIP mode is not part of the IPSec standard, it combines high speed with all levels of encryption.

Anti-Replay Service and Use of Unique X .509 v .3 Certificates
Ravlin 10 uses IPSec anti-replay services to ensure that rogue packets cannot be inserted into a Ravlin-protected data stream. With anti-replay service, each IP datagram passing within the secure association is tagged with a sequence number. On the receiving end, the datagram is blocked if its sequence number does not fall within a pre-specified range of sequence numbers.
