  text: "Version Control Systems (VCS) are a valuable tool for software development\r\nand
    document management. Both client/server and distributed (Peer-to-Peer)\r\nmodels
    exist, with the latter (e.g., Git and Mercurial) becoming\r\nincreasingly popular.
    Their distributed nature introduces complications,\r\nespecially concerning security:
    it is hard to control the dissemination of\r\ncontents stored in distributed VCS
    as they rely on replication of complete\r\nrepositories to any involved user.\r\n\r\nWe
    overcome this issue by designing and implementing a concept for\r\ncryptography-enforced
    access control which is transparent to the user. Use\r\nof field-tested schemes
    (end-to-end encryption, digital signatures) allows\r\nfor strong security, while
    adoption of convergent encryption and\r\ncontent-defined chunking retains storage
    efficiency. The concept is\r\nseamlessly integrated into Mercurial---respecting
    its distributed storage\r\nconcept---to ensure practical usability and compatibility
    to existing\r\ndeployments."
