Developers face a huge challenge in finding a transparent security system for use in cloud computing, says storage supplier Origin Storage.
Security experts have predicted that it will take up to 10 years for cloud computing to achieve the security assurances that will enable it to become the norm in business.
Vulnerabilities in password reset functions for online services from Amazon and Microsoft have cast fresh doubt on the security of cloud computing.
Researchers demonstrated the flaws in Amazon's Elastic Compute Cloud and the online version of MS Office at last week's Black Hat security conference.
"As long as user-friendliness comes ahead of security, password resets and other security mechanisms will be the weakest links," said Any Cordial, managing director at Origin.
"Even once a solution is found, it will take time to get that technology accepted and widely used."
In the meantime, businesses can take advantage of mature encryption technologies to secure data locally to military standards on the fly, he said.
