Research in Motion, embroiled in a security row with the Indian government, has told customers it is committed to ensuring their emails are safe from snoopers, an AFP report said.
The statement received by AFP followed Indian media reports that RIM might allow the Indian government access to messages sent using a BlackBerry.
India, battling a host of insurgencies from Kashmir to the far-flung northeast, has raised fears the cellular device could be used by terrorists to communicate, the AFP report said.
RIM said it wished to assure customers it was committed to 'serving security-conscious businesses in the Indian market with highly secure' products and rejected what it said was incorrect speculation.
The Indian media reports said India's government wanted 'the master key' to allow them access to emails sent between BlackBerry devices.
But RIM said no 'master key' existed.
RIM does not possess a 'master key' to gain 'unauthorised access' to data and there is no 'back door' in the system that would allow RIM or any third party to gain access, the company statement said.
BlackBerry's security system is based on 'a key system whereby the customer creates their own key and only the customer ever possesses a copy of their encryption key,' RIM said.
