This paper points out the security demands of an Ambient Assisted Living (AAL) application and demonstrates the usage of proxy re-encryption in order to fulfil its security requirements for storage and distribution of sensitive data. Because AAL systems often exhibit the same security needs as the application developed in the presented project, the described implementation can serve as a point of reference for similar projects.enText/Conference Paper1617-5468
