Security Special: Digital Signatures
It’s early days for digital signatures in India
Though Indian enterprises are gradually adopting digital
signatures and cryptography, things are still in the pilot stage, says Abhinav
Singh

by Indian enterprises has been pretty pathetic and highly disappointing
due to the lack of awareness about the concept, says Pavan Duggal |
The market for digital signatures and cryptography got
a shot in the arm from the Government of India’s IT Act, 2000, when the authorities
came out with a detailed policy on digital signatures, gave legal status to
digital signatures and recognised e-commerce transactions. Section 3 of the
IT Act states that any subscriber may authenticate an electronic record by affixing
his digital signature to it. However, three years after this watershed event,
adoption of digital signatures in India, especially by government departments,
is slow. The silver lining is that usage is picking up in organisations such
as the Director General of Foreign trade (DGFT). Educational institutions like
the DOEACC (Department of Education for Accredited Computer Courses) and IGNOU
(Indira Gandhi National Open University) are using digital signatures to help
students register online.
E-commerce—the white knight that wasn’t
Shopping and auction sites such as Sifymall,
Baazee, Rediff and Fabmall are employing digital certificates to prove to visitors
that they are who they claim to be. With organisations like the Indian Railways
and various airlines offering online ticketing and booking facilities, valid
digital certificates and signatures are essential for maintaining authenticity
and credibility.
Net banking—secured by cryptography
IDRBT (Institute for Development and Research
in Banking Technology), the technology arm of the Reserve Bank of India, is
pushing the concept of digital signatures with nationalised banks. Online banking
transactions are driving the usage of digital signatures and certificates are
gaining ground in the banking sector. Many Indian banks—ICICI Bank, Citibank
and HDFC Bank are notable mentions here—as well as the National Stock Exchange
and many share depositories are also using digital certificates on their websites.
This is powering the market for server certificates that let visitors to a site
authenticate the site’s identity so that they feel secure while communicating
with their bank or depository online. Server certificates let financial institutions
and their customers exchange confidential information in a secure manner. Digital
signatures in the server certificate are used to generate the hash for encrypting
and decrypting SSL traffic to and from the e-commerce server. This kind of certificate
is useful for B2B sites such as supplier portals that let a company’s Tier 2
and 3 suppliers access information regarding product availability, shipping
dates and manage inventory.
Growing Net usage is helping
Despite pathetic infrastructure, Internet
usage in India is on the rise, leading to a growth in the number of personal
certificates being used by individuals. The killer app here is to sign e-mail
with a personal digital certificate. That said, server certificates are more
popular.
Surendra Singh, who heads RSA Security’s
South-Asian operations says, "Server certificates are more popular than
personal certificates as people still fear that legal disputes may arise as
a consequence of using personal certificates."
Trimming the paper trail
The need to reduce the quantum of paperwork
in an organisation is another driver. Companies prefer to conduct legal and
business transactions online and are adopting certificates that authenticate
such transactions. Suresh Raman, head of Marketing at Microland, says, "Digital
signatures and certificates are a step in the direction of minimising paperwork."
Popular software such as Outlook Express, Outlook and Netscape Mail come equipped
to handle digital certificates.
Urmez Daver, marketing services manager
for Safe-Scrypt says, "Very rarely do we see a product which is not capable
of handling digital certificates and signatures. We just have to plug in certificates
into the existing products."

Dipping a toe in cryptographic water
Indian enterprises are evaluating digital
signatures and certificates. Although a large number of enterprises use them
for signing e-mail, they are still running pilot projects to assess the usability
of digital signatures. The banking, financial services and insurance sector
cannot do without digital certificates for its online presence, but Indian enterprises
seem to feel that they can do fine without them for the greater part. Pavan
Duggal, advocate at the Supreme Court of India and founder president of Cyber
Law India says, "The adoption rate for digital signatures in India by Indian
enterprises has been pretty pathetic and highly disappointing due to the lack
of awareness about the concept. The dotcom bust and the consequent condition
of the economy has also contributed to this scenario."
Glacial growth
Talk to vendors and it’s apparent that
the adoption of digital signatures and certification isn’t going to skyrocket
very soon. Companies selling these solutions are hoping that the market will
take off in the next couple of years. There are concerns regarding uniform control
and policy over certifying authorities. The Controller of Certification Authorities
(CCA) of the Ministry of Communication & Information Technology has given
ICICI Infotech the contract for the supply and installation of the National
Root Certification Authority, with an aim to bring uniformity amongst different
certifying authorities in India. Duggal adds, "Once banks and other government
enterprises start using digital signatures in a big way, it will be a turning
point in the usage and adoption of digital signatures and certificates in India.
People will then get convinced about the merits of digital signatures and about
their need and utility in day-to-day life."
Adoption rates may be slow but the next
couple of years are expected to see a rise in the usage of cryptography. Raman
of Microland says, "There were few takers for credit cards five years ago
but now their usage has taken off in a big way." He expects the same to
happen with digital signatures and cryptography as well.
Taxation of e-commerce transactions is
hampering widespread usage of digital signatures and certificates. K Vaitheeswaran,
vice-president at Fabmall says, "Unlike in the US where all e-commerce
transactions are tax-free, we have to pay tax on every transaction in India.
Tax varies from product to product. This is a major issue that discourages vendors
from venturing into e-commerce in India. That, in turn, leads to lower growth
of digital signatures and certificates."
Any way you look at it, digital certification
is in a primitive stage in India. Acceptance will come only if Internet commerce
takes off big time or if companies start seeing the benefits of using digitally
signed documents to reduce the paper trail.

Digital certificates play a pivotal role in ensuring authentication and
non-repudiation, while authorisation, integrity and confidentiality gets
taken care by other elements of PKI (Public Key Infrastructure).There
are various PKCS (Public Key Cryptography Standards) that form the basis
of this technology. The strength of encryption is measured in bitsthats
basically a reference to how big the key is. The bigger the key, the stronger
the encryption. 128-bit encryption is prevalent today.
Digital signatures use what is known as public key cryptography,
which employs an algorithm using two different but mathematically related
keys. One key is used to create a digital signature or transform
data into a seemingly incoherent form. The other key is used to verify
a digital signature or return a message to its original form. Another
fundamental process, thats known as a hash function,
is used in creating and verifying a digital signature. A hash function
is an algorithm which creates a digital representation or fingerprint
in the form of a hash value or hash result of
a standard length, which is usually much smaller than the message but
nevertheless unique to it. Any change to the message invariably produces
a different hash result when the same hash function is used. Hash functions
are what let the software used to create digital signatures assure you
that there has been no modification of the message since it was digitally
signed.
