- Hardcore Security -- Chip-level implementation bolsters
- encryption technology for electronic commerce
-
- By David Joachim
-
- If data encryption tasks are bogging down your systems, it may be time to
- consider some new options.
-
- Intel and a slew of other hardware manufacturers are behind a wave of
- new devices designed to make encryption faster and more secure. These
- products are the latest evidence that encryption, essential for secure
- electronic commerce and communications via the Internet, is migrating
- from software-based technology to hardware-and the pace is picking up.
-
- In the long run, encryption technology will be embedded directly into the
- core of PCs, servers, switches and other devices, including high-volume
- chips such as the Pentium. But that won't happen for years, experts say.
-
- In the interim, leading hardware vendors are providing a host of new
- products designed to add hardware muscle to Web servers and other
- systems that can get bogged down by RSA data encryption, the Data
- Encryption Standard and other compute-intensive cryptographic
- algorithms.
-
- Some systems can experience as much as a hundredfold performance
- drop once encryption is turned on, analysts said.
-
- "RSA should stand for Really Slow Algorithm," said Peter Craig, vice
- chairman of Rainbow Technologies, a network security developer in
- Irvine, Calif. "As you turn this stuff on, you discover that your server
- transaction capacity goes from several hundred transactions a second to
- three or four per second."
-
- Intel is preparing a coprocessor designed to handle encryption in various
- hardware devices, and several OEMs and sources close to the company
- had expected an announcement at the RSA Data Security Conference in
- San Francisco next week (CommWeek, Jan. 13). Several OEMs also
- confirmed plans for systems based on an Intel crypto-chip.
-
- But Intel said last week there would be no announcement at the show,
- though officials confirmed that they are working on such a product.
-
- Other vendors, however, are not waiting for Intel to set the pace and plan
- their own product introductions at the RSA conference.
-
- Atalla, a San Jose, Calif., subsidiary of Tandem Computers Inc., will
- debut a PCI card for handling data encryption on Web servers. Atalla's
- card actually is a miniature version of its WebSafe unit, a closed system it
- calls a "co-server" for off-loading Web transactions. Starting at $12,500,
- WebSafe is designed to erase encrypted data when a breach is
- attempted. Pricing for the unnamed PCI card has not been set.
-
- Atalla, a developer of secure banking systems, also will join partner VLSI
- Technology Inc., San Jose, to introduce a cryptography chip called
- NetArmor for use in motherboards, set-top boxes and other server-side
- devices. It starts at a unit price of $50 in volumes of 10,000 or more.
-
- VLSI is set to debut a crypto-chip called GhostRider, developed with
- Lucent Technologies Inc., Murray Hill, N.J., for use in PCTV consumer
- devices.
-
- A number of other vendors also will showcase new hardware solutions at
- the show, including Rainbow Technologies and Spyrus Inc., San Jose,
- Calif.
-
- Adding Muscle
-
- The new product category is aimed at several concerns. On the server
- side, the offerings closely resemble math coprocessors for off-loading
- heavy computations, though most also include special "firmware," or
- unerasable software, as well as secure storage for private keys that
- identify a group or company doing business on the Internet.
-
- On the client, however, secure E-mail and other mobile applications are
- driving the development of new smart cards and PC Cards, so-called
- tokens that not only store private keys for authentication but any type of
- data an end user wants to store securely and take with him, such as credit
- card numbers and virtual keys to the corporate network.
-
- Kevin McCurley, a cryptology expert at the U.S. Department of Energy's
- Sandia National Laboratories, Albuquerque, N.M., said storing such data
- on hardware is far more secure. "It's very difficult to protect private keys
- in software, which is why we have seen so many breaches," he said.
-
- Spyrus will introduce at the show PC Card devices adapted from
- products previously only sold to the government, said Charles Walton, the
- company's director for electronic commerce. They are the Hydra Privacy
- Card on the client, with 64 megabytes of storage; and the MultiCard
- Accelerator, an array of two to 14 PC Cards for servers. Pricing starts at
- $500 for cards with no memory.
-
- Hewlett-Packard and IBM also market PC Cards and PCI cards for use
- on their systems.
-
- To appreciate the advantages of hardware, consider these "hard tokens"
- to be miniature computers dedicated solely to one function. "On a hard
- token, your keys and other information are not visible to anything else but
- the card it's running on," said David Bernstein, editor of Infosecurity
- News, a newsletter based in Framingham, Mass.
-
- "If the keys are in software, and your computer is the token, that data is
- visible to other processes of that machine and callable by your computer,
- so it can be hacked," Bernstein said.
-
- The downside of hardware is that once private keys and other variables
- are set, they cannot be changed, Bernstein noted.
-
- Last year there were only a handful of hardware options for encryption;
- this year there are dozens, and all the top silicon vendors have staked a
- claim. Motorola, Mitsubishi, National Semiconductor, NTT, Siemens and
- VLSI, among others, have recently shipped processors optimized for
- encryption.
-
- Experts agree that encryption support will one day be built into all
- processors. "It needs to become something everyone needs and everyone
- is willing to pay for," said Jim Bidzos, RSA Data Security president.
- "That's about five to 10 years off."
