Abstract

Outsourcing keys (including passwords and data encryption keys) to professional password managers (honest-butcurious service providers) is attracting more and more attention from the researchers and users in the era of cloud computing. However, existing solutions in traditional data outsourcing scenario are unable to simultaneously meet the following three security requirements for keys outsourcing: 1) Confidentiality and privacy of keys; 2) Search privacy on identity attributes tied to keys; 3) Owner controllable authorization over his/her shared keys. In this paper, we propose CloudKeyBank, the first unified key management framework that addresses all the three goals above. To implement CloudKeyBank efficiently, we propose a new cryptographic primitive named Searchable Conditional Proxy Re-Encryption (SC-PRE) which combines the techniques of Hidden Vector Encryption (HVE) and Proxy Re-Encryption (PRE) seamlessly.
