Block Encryption in Cloud Computing Using Key Trees

Volokita A.N., Kohanevich I.V.

Providing secure is an important component of cloud computing. Furthermore, the lack of sufficient data security is a main constraint to move to the “cloud”. The article is devoted to data encryption in cloud computing. The author considers a distributed file system in which files are divided into separate blocks. Then he describes a method of encryption of these blocks based on a binary tree of keys. Moreover the author explains a way of constructing of this tree. The paper considers the prospects for further development of the proposed method.
