New Delhi, (Agencies): Hardening its stance against Blackberry for not providing a solution to intercept Enterprise mail services, the government on Sunday said telecom operators will have to stop any such services that cannot be monitored as per the satisfaction of law enforcement agencies.

BlackBerry-maker Research in Motion (RIM) has been saying that it cannot provide access to the popular BlackBerry Enterprise Service (BES) as it does not possess any key and the security architecture is the same around the world.

He noted this was in line with a condition in the licence agreement between the government and service providers that states, "Whoever uses your network, we must be able to intercept that in a form to the satisfaction of the Law Enforcement Agency."

Asked whether the government has extended the deadline of January 31 for RIM to provide a solution to the satisfaction of LEAs, Pillai said, "We have not extended the date, but it has not been terminated also."

Eight operators including Bharti, Vodafone, Idea, RCom, Tatas and also two state owned firms -- BSNL and MTNL – are offering BlackBerry services across the country and it has emerged a popular service among corporates for its enterprise mail service.

RIM vice-president (Industry, Government and University Relations) Robert E Crow, who was in India recently, had said, "There is no possibility of us providing any kind of a solution. There is no solution, there are no keys to be handed... It's not possible to do so because the keys of the service are in possession of the corporate enterprises."

However, the argument is not bought by the security establishment.

The Home Secretary said, "Even messenger services – they all said we can't do it... We can't do it... Only when we said, okay, we are gonna close it down, they came and said here is the solution. I have a feeling... under pressure they'll do it."

There are over one million BlackBerry subscribers in India and the number is growing fast. Indian security agencies have been demanding access to all BlackBerry services as part of efforts to fight militancy and security threats over the Internet and through telephone communications.
