Abstract: A method is provided to share a content stored on a secured server. The content is associated to a first electronic device and encrypted using a public key of the first electronic device. The secured server stores a first re-encryption key from the first electronic device to a second electronic device. The method is implemented by the secured server and includes the steps of determining association of the content with the second electronic device, re-encrypting the content using the first re-encryption key, sending the content to the second electronic device for encryption using a second device public key and storing the encrypted content received from the second electronic device in association with the second electronic device.
