Researcher: Prof Mark Ryan
Research Institution: University of Birmingham
Overview:
Prof Mark Ryan from the University of Birmingham is seeking investors, industry partners, developers and potential users to support the development of in browser cryptography technology.
Product:
• Confidentiality focused system that supports applications, evaluations, and decisions
• Cryptographically protects the applications, evaluations, and decisions from the cloud provider
• Provides differentiated access control allowing applications to be submitted and evaluated by panel members
Market:
• Users of online systems that involve and application process and a separate evaluation process, for example, online recruitment or tender management systems
• Users of systems that require a high level of privacy
Benefits:
• Uses private and symmetric keys which are stored in a KeyPurse
• KeyPurse is protected with a secure password derived key which allows the KeyPurse to be stored on the server and facilitates the use of ConfiChair from anywhere
• Uses a method of data re-encryption to enable the administrative role user, such as the conference chair or platform manager, to provide differentiated access control
• Re-encryption process is performed offline without the server seeing any decrypted text
• Uses Stanford JavaScript Crypto Library (SJCL) and HTML5 to enable cryptographic functionality in modern browsers
• Tests have shown that the in-browser key-translation can be performed in less than 5 minutes for 1000 papers
• Works under the malicious-but-cautious threat model which assumes that the cloud will try to access (and process) the information it receives but only if it is impossible to detect
Partners:
Investors, industry partners, developers and potential users are sought to support the development of Confi-Chair.
