A Key-Policy Attribute-Based Temporary Keyword Search Scheme for Secure Cloud Storage
Abstract
Introduction
A Key-Policy Attribute-Based Temporary Keyword Search scheme for Secure Cloud Storage Cloud computing today plays an important role in our daily lives because it provides at a very low price efficient, reliable and scalable resources for data storage and computational activities. The cloud’s direct access to its users ‘ sensitive information, however, threatens their privacy. A trivial solution is to encrypt data before outsourcing it to the cloud to address this problem. Searching for encrypted data, however, is very hard. Public key encryption with keyword search (PEKS) is a primitive cryptographic that was first introduced by Boneh et al. to facilitate the search of encrypted data.

Conclusion
Securing cloud storage is a major issue in cloud computing. We addressed this issue and introduced the notion of temporary keyword search (KPABTKS) based on key-policy attributes. Each data user can generate a search token that is valid only for a limited time interval, according to this notion. For this new cryptographic primitive, we proposed the first concrete construction based on a bilinear map.
