Increasing security of objects in cloud environments by using a two-part encryption scheme

Abstract:

Provided are techniques for increasing security of objects in cloud environments by using a two-part encryption scheme. Objects to be stored in a cloud node are received. A number of keys to be used is determined. That number of keys are obtained. A sequence for the keys is obtained. The keys are concatenated using the sequence to form a concatenated key. The concatenated key is hashed to form an encryption key. Each of the objects is encrypted using the encryption key to form encrypted objects.
