Definitions
- the invention relates to the field of network security protocol conversion.
- the invention relates to the conversion between the Wireless Transport Layer Security and Secure Sockets Layer protocols.
- the Wireless Application Protocol defines a set of protocols for wireless applications.
- the Wireless Transport Layer Security (WTLS) is the security layer of the WAP and provides privacy, data integrity, and authentication for WAP services.
- WTLS is based on the Transport Layer Security (TLS), a security layer widely used in the Internet, with modifications to accommodate bandwidth, datagram connection, processing power, memory capacity, and cryptography limitations typical in wireless communications.
- TLS Transport Layer Security
- SSL Secure Sockets Layer
- the common method of converting between SSL data and WTLS data uses software executing inside a WAP gateway. Wireless messages travel through the air to a carrier's receiver, where they are received and passed to the gateway. If the message is WTLS encrypted, the encrypted message is decrypted, then encrypted using SSL. If the message is SSL encrypted, the encrypted message is decrypted, then encrypted using WTLS. Then, the encrypted message is transmitted out of the gateway.
- the data is decrypted and stored in the memory of the WAP gateway temporarily, allowing a period of time when the message is unencrypted and unprotected in the WAP gateway. This creates a security vulnerability. Furthermore, since the conversion is done using software, a considerable amount of CPU resources are consumed and a latency in the response to a client request may be experienced.
- Figure 1 illustrates an embodiment of a system implementing the invention.
- Figure 2 illustrates an example of a security procedure implemented with an embodiment of the method of the invention.
- Figure 3 illustrates an embodiment of a board according to the invention.
- Figure 4 illustrates an embodiment of the method of the invention.
- System 100 includes a service provider 102, a client 104, and a content provider 106.
- the client has a device 110.
- the device 110 is a wireless device, which typically uses Wireless Application Protocol (WAP), a set of protocols for wireless applications.
- WAP Wireless Application Protocol
- the content provider 106 has a server 112 to store content.
- the service provider 102 provides a gateway 108.
- the gateway 108 connects the client 104 to the content provider 106.
- the gateway 108 encrypts and decrypts data as necessary to provide compatibility between the different protocols used by the client and the content provider.
- the client device 110 typically encrypts data according Wireless Transport Layer Security Protocol (WTLS), a security layer for WAP that provides privacy, data integrity, and authentication for WAP services.
- WTLS Wireless Transport Layer Security Protocol
- SSL Secure Sockets Layer Protocol
- the gateway 108 contains a security acceleration board 114 for decrypting and encrypting data.
- the board 114 is a plug and play device that fits into a Peripheral Component Interconnect (PCI) slot or a single or dual in-line memory module (SIMM or DIMM) slot.
- the client uses the device 110 to send a request 116, which is encrypted according to an encryption scheme.
- a client may use a cellular phone to send a request for an Internet web page.
- the request 116 is received in the gateway 108.
- the board 114 decrypts the request 116 and encrypts the request according to another encryption scheme.
- the request is encrypted according to WTLS.
- the board 114 may decrypt the request and encrypt the request according SSL.
- the request 118 is sent to a content provider 106.
- the content provider accesses the requested content and sends a response 120, which is encrypted according to an encryption scheme.
- the response is encrypted according to SSL.
- the response 120 is received in the gateway 108.
- the board 114 decrypts the response and encrypts the response according to another encryption scheme.
- the board decrypts the response and encrypts the response according to WTLS.
- the response 122 is sent to the client device 110.
- FIG 2 an example of a security procedure implemented with an embodiment of the method of the invention is illustrated.
- the client provides the gateway with an indication of security parameters, including security protocol and cryptographic parameters.
- the gateway receives data encrypted according to a first encryption scheme.
- the data and security parameters are transmitted to the board.
- the board decrypts the data and prevents access to the data from outside the board.
- the gateway initiates a security protocol handshake with a server, and they both agree upon the required security parameters.
- the board receives security parameters from the gateway.
- the board encrypts the data according to a second encryption scheme and transmits the data to the gateway.
- the gateway transmits the encrypted data to the server.
- a similar security procedure is used when data from the server is received by the gateway and transmitted to the client.
- FIG. 3 illustrates one embodiment of the security acceleration board 114 of the invention.
- the board includes a controller 300 and a hardware device 302.
- the controller receives data and security parameters from a bus 306.
- the controller is a Field Programmable Gate Array (FPGA).
- the data is encrypted according to an encryption scheme.
- the controller 300 determines what conversion is needed and then transmits the data to the hardware device 302.
- the hardware device 302 is a programmable hardware device.
- the hardware device 302 may be a FPGA.
- the hardware device 302 is a non-programmable hardware device.
- the hardware device 302 may be an Application Specific Integrated Circuit (ASIC).
- ASIC Application Specific Integrated Circuit
- the data is stored in a memory 308 during the conversion process.
- the controller 300 controls the access of memory 308.
- the controller 300 prevents access to the memory from outside the board 114. This prevents the gateway 108 and sources outside the gateway from accessing the memory.
- board 114 includes a second hardware device 304.
- the hardware device 302 does the decryption and encryption of data according to one encryption scheme while the second hardware device 304 does the decryption and encryption of data according to another encryption scheme.
- the board 114 is used to convert data from WTLS to SSL and from SSL to WTLS.
- the hardware device 302 may be configured for SSL encryption and decryption while the second hardware device 304 may be configured for WTLS encryption and decryption.
- the controller 300 will transmit the data to hardware device 302 to decrypt the data. Then, hardware device 302 will transmit the data to the second hardware device 304 to encrypt the data according to WTLS. The data is then transmitted to the controller for forwarding out of the gateway. Conversely, if the data received at the controller is WTLS encrypted, the controller will transmit the data to the second hardware device 304 to decrypt the data. Then, the second hardware device 304 will transmit the data to the hardware device 302 to encrypt the data according to SSL.
- the second hardware device 302 is a programmable hardware device, for example, a FPGA. In another embodiment of the invention, the second hardware device 302 is a non-programmable hardware device, for example, an ASIC.
- Figure 4 illustrates one embodiment of the method of the invention.
- data is received at a first hardware device encrypted according to a first encryption scheme.
- the data is received from a controller.
- data and security parameters are received at the first hardware device.
- the data is decrypted at the first hardware device.
- the data is then transmitted to a second hardware device.
- the data is encrypted according to a second encryption scheme.
- the data is encrypted according to a second encryption scheme at the first hardware device.
- the data is encrypted according to a second encryption scheme at the second hardware device.
- the decrypted data is stored and retrieved during the conversion from the first encryption scheme to the second encryption scheme.
- the data may be stored in a memory.
- access to the stored decrypted data from outside the board 114 is prevented. This prevents access to the stored decrypted data from the gateway 108 and any source outside the gateway.
- access to the stored decrypted data is prevented by the controller 300.
- the data encrypted according to the second encryption scheme is transmitted to the controller to forward out of a gateway.
