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."
