i got to speak to cryptography research inc, a company which i would expect, or at least hope much of the core value chain would have heard of. if not, then read on. i spoke with paul kocher, president & chief scientist, kit rodgers, business development & director of licensing and ken warren, smart card business manager .
cryptography is the ancient science of encoding messages so that only the sender and receiver can understand them. cryptography is now available to everyone thanks to the development of modern computers, which can perform more mathematical operations in a second than a human being could do in a lifetime. an ordinary pc can produce codes of such complexity that the most powerful supercomputer using the best available attack algorithms would not break them in a million years. cryptography is used to secure telephone, internet, and email communication and to protect software and other digital property .

sony' s victory in the dvd format wars was largely due to its embrace and toshiba' s rejection of a sophisticated anti - copying scheme that promises to be relockable should it be cracked at some point in the future .
toshiba earlier this week announced that it will stop making hd dvd players, surrendering the field in a five - year battle with sony' s blu - ray to become the disc format of the future .
support from studios has been widely cited as the reason for blu - ray' s victory, but few consumers know that the studios were likely won over by the presence of a digital lock on movies called bd +, a far more sophisticated and resilient digital rights management, or drm, system than that offered by hd dvd .
“the adoption of bd + as part of the blu - ray disc specification … was a key factor in our decision to publish on the format, ” twentieth century fox home entertainment executive mike dunn said in a 2007 press release. “this added layer of content protection gives blu - ray yet another distinct competitive advantage. ”
the triumph of drm for video will almost certainly lead to continued attempts to hack the system, and risks alienating users who want to buy content once and have it available on whatever brand of tv, laptop, mp3 player and smartphone they own. that fight lasted for years in the music world, though it' s now clear that drm for music is in its final throes .
both blu - ray and hd dvd formats use an anti - copying system called aacs, which has already been cracked; but blu - ray employs bd + as an extra layer of protection. bd + is optional – not all blu - ray discs use it – and has not yet been compromised, despite claims to the contrary .
when the player spins up the disc, the virtual machine software and the dvd player view each other with mutual suspicion, but initiate a complicated mating ritual involving checks of cryptographic keys .
once the disc decides the player is legitimate and hasn' t been compromised, it allows the movie it contains to be decrypted for playback .
but if the disc detects that the player has been modified to record the movie, or it is using stolen keys from a different player, the disc won' t play. unlike aacs, however, bd + has no ability to disable a player permanently, nor does its software linger after a disc is ejected .
i don' t want to pretend that security was the only thing that drove the content war ,
kocher said .
but from a content perspective, i think security is the biggest overhang over the future of the studios and i think they realize that and they are doing what they can to deal with that .
while file sharers who hang out at forums like doom9 might not appreciate kocher' s latest effort, kocher was also the co - author of the ssl 3. 0 specification, which allowed real security for online logins and online credit card purchasing .
kocher says he' s a technologist who had no desire to get caught up in a format war, and offered the technology to both camps. but toshiba decided that aacs was enough security .
instead of being on both formats, it became a differentiator and attracted content to blu - ray and gave blu - ray some momentum ,
kocher said .
the bd + system was cited by lionsgate and fox studios as the key reason they supported the format over hd dvd .
in october, fox released the first discs to use bd +, but some first - generation players couldn' t handle the bd + and required firmware updates. once the updates became available, users had to download a file, and burn a cd from an. iso file to update their dvd players – a high technical hurdle for many .
that minor debacle has already led to a class - action suit against samsung, though kocher dismissed the issue as something to be expected when buying first - generation hardware .
the bd + system protects movies if pirates should develop mod chips for blu - ray players or develop blu - ray player software that allows movies to be copied .
bd + can surreptitiously insert data about a player into a playback stream. if a movie is then pirated, studios can analyze the data and come up with a way to prevent that machine from doing the same to future releases .
andrew jaquith, a senior analyst at the yankee group, says the bd + scheme appeals to studios because it can be patched .
there is an element of renewability in bd + and that is the path to longevity ,
jaquith said .
there are always implementation flaws. it' s an arms race and to stay agile, you have to have the ability to pull up the gates when the ramparts have been breached .
but jaquith says security was more likely an
influencing factor
than a
leading factor
for studios, which he believes eventually chose blu - ray primarily for hardware and software reasons .
kocher' s company began brainstorming a better way to lock down dvds shortly after the discs hit the market in the late 1990s .
his company already had some relationships with the movie industry, having developed systems to let studios securely transfer movie files inside a company while they were being worked on, and in a july 2003 workshop in los angeles, the company demonstrated their technology to studios in a workshop meeting .
hardware makers pay a nominal fee for the specs and must include the technology in their players, while studios pay only when they include bd + code in their titles .
kocher fully expects that the hacker community to attack bd + and that its backup mechanisms will be needed .
if you run a bank, someone will try to rob it someday ,
kocher said .
just because no one has brought a gun in and pointed at your teller, doesn' t mean that they won' t in the future .
when asked if he hoped to see how well bd + holds up under the kinds of sustained attacks that compromised hd dvd last year, kocher hesitated .
you don' t hope the first layers of defense go and you have to go to the subsequent ones ,
kocher said .
but that said, there' s always a piece of you that wonders how it is going to play out and when you look forward 10 years from now – did we drastically underestimate the pirates ?
at the same time, you don' t want to encourage that ,
kocher said .
it' s what causes restrictive laws to get passed .

rambus, which develops and licenses memory technology, said the acquisition will expand its semiconductor licensing portfolio to include cri' s intellectual property (ip) for content protection, network security and anti - counterfeiting .
cri is run by noted cryptographer paul kocher, who has been credited with helping author the ssl (secure sockets layer) 3. 0 standard. cri' s licensees include samsung, toshiba, infineon, microsoft, and nxp. rambus said that over five billion semiconductor products are made annually under cri' s license .
rambus is primarily known as a memory technology company for pcs and servers. the company recently expanded its range of offerings to include leds (light - emitting diodes) and mobile devices .
cri' s security technologies could apply across a range of technologies in rambus' ip portfolio, rambus' ceo harold hughes said in a statement .
with many billions of connected devices conducting electronic transactions, storing important personal data, and delivering copyrighted content, the needs for security are paramount ,
hughes said .
rambus licenses ip to chip makers, who are increasingly interested in adding security features on hardware. intel in february completed the acquisition of security company mcafee for $ 7. 68 billion. intel at the time said that mcafee would help boost its software and on - chip security offerings .

at the cartes smart card exhibition early this month, i got a chance to meet up with a number of companies offering new solutions to the market. there was a lot of talk surrounding contactless technology and the potential uptake in the short to medium term .
while the smart card market is global with booming growth in some geographic regions the majority of the industry have their headquarters and design centres based in europe. cri are looking to increase their presence in the european market. by doing this, i believe cri are showing their commitment to the smart card industry which allows them to provide the support needed to improve security. the introduction of ken warren has bolstered cri’s effort and will allow cri to leverage their effort from ken’s vast experience in the industry. he will ensure european customers can successfully implement cri' s patented countermeasures, and he will actively represent cri in all european smart card industry activities .
i take this opportunity to provide feedback of some of the things we discussed .
kit: first, i definitely do not want to convey that smart cards are insecure. in fact, smart cards are one of the most secure technologies available. as you know, smart cards are tamper - resistant, self - contained modules which can offer excellent protection at a reasonable cost. however, no device can guarantee absolute security and smart cards are no exception. there is also significant variation among smart cards; some low - end cards offer very limited security, while the best cards are among the most secure devices available anywhere. dpa attacks are a significant concern for smart cards because the attacks are unfortunately very powerful and easy to replicate. the good news is that smart cards can be made very resistant if manufacturers implement proper countermeasures .
kit: cri discovered dpa in the mid 90’s. at the time we worked closely with the industry to educate leading issuers, smart card manufacturers and silicon suppliers about dpa on both a technical and business level. today cri remains a leader in helping organizations worldwide develop products that are secure against dpa by :
kit: silicon providers and smart card manufacturers must work together in both hardware and software to ensure their devices are secure against dpa. vulnerabilities can exist at both the hardware and software level. particular attention needs to be paid to the interface between hardware and software components .
kit: indeed, card issuers (and individual users) are the ones that ultimately suffer when fraud or other attacks occur. issuers definitely need to be focused on security issues, including dpa, and should demand that their suppliers provide products with effective countermeasures that have been properly tested. in terms of licensing our technology, issuers should check with their smart card suppliers to see if their products are properly licensed. some issuers have chosen to license with us directly, while others are requiring that their smart card suppliers implement and license the necessary dpa countermeasures as part of their products. ultimately, our objective is to be sure each device using our technology has been licensed, but it does not matter if the silicon supplier, card manufacturer, or issuer pays the royalty .
kit: we do not believe there is a way to make dpa - resistant smart cards without using our technology. one of the advantages of discovering dpa is that we were able to focus on developing countermeasures before anyone else. thus, we spent considerable effort ensuring our patents broadly cover the fundamental approaches for countering dpa attacks. while technologists in the security and smart card communities have been actively researching dpa over the last few years, their developments build upon our foundational patent portfolio .
kit: dpa attacks do not require any expensive hardware; a pc and under $ 1, 000 worth of equipment is sufficient .
kit: security risks are always greatest in situations where it’s worth somebody’s effort to mount attacks. smart cards used for banking, pay television, and mass transit have always been major targets for fraud and piracy. on the government side, defense and identity applications also face particularly serious threats. gsm sims are also an area of increasing focus, particularly as applications become more complex and integrated with various forms of commerce. in general, any application where smart card is being used for security reasons is a potential target .
kit: issuers and users can feel safe if their smart cards include properly implemented and licensed countermeasures. we are not sharing detailed pricing information at this time, though as a general philosophy we want our business to succeed along with the proliferation of smart cards .
me: can you tell me a little more about cri - i. e. what are your main markets ?
kit: cri is a combination technology licensing and security services firm. we’re nearly 10 years old and are headquartered in san francisco. our business seeks to anticipate fraud and piracy trends and then develop technologies that help solve those problems. for instance, our clients are happy to pay us a few cents for a technology if they know it is likely to save them a few dollars in fraud or piracy costs. we’ve been quite successful implementing this model to date. in addition to our dpa countermeasures, our licensing efforts also include a custom security asic technology called the cryptofirewall (tm) for pay television systems and security architecture for securing high - definition video on next - generation optical media formats .
kit: the smart card industry is a very important market for us. we’re also having great success with anti - piracy technologies. while it’s hard to predict which will grow faster, we’re very enthusiastic about the smart card industry over the long term, and we see our technology licensing program growing with the industry .
kit: for now, we’re focused on negotiating licenses with the vendors that are the most proactive about obtaining security technologies for their customers. we are also continuing to work closely with testing labs and other security experts to help ensure smart cards are secure. we also recently started our european operation, which we plan to expand to increase the visibility and importance of our licensing program among card issuers and users. a final area of focus is our dpa logo program, which will be increasing in visibility over the months ahead .
