At a keynote speech on the first day of the Networks Show in Birmingham, Dr Steve Marsh, director of security policy, at the Office of the e-Envoy, said: "Two-thirds of people don't trust the security which is being offered by Government and business, and we must do more to more to win confidence."
Marsh admitted that the use of digital certificates was still limited in business. He said schemes to spread strong authentication among the general public had to be found, but the industry had so far been unable to develop cheap and easy to install systems.
The UK Online campaign, to be launched in the autumn, was an opportunity for business and the public sector to reverse the trend of slow take-up of secure e-commerce said Marsh. The Government is looking for business partners to sign-up for the campaign.
Marsh said 42% of the 520 Government identified e-services were now available online. He said this figure would reach 73% by the end of this year.
He did not directly answer the criticism from the government's spending watchdog, the National Audit Office, that too few services were genuinely interactive.
Marsh did, however, say between 15% and 20% of e-governmtn services would require strong authentication.
