Abstract
The present invention relates to an attribute-based encryption technology of safety outsource. The attribute-based encryption technology comprises the steps of (1) system establishment, (2) outsource key generation initiation, (3) external key generation, (4) internal key generation, (5) conversion key blinding, (6) encryption, (7) partly decryption, and (8) complete decryption. The attribute-based encryption technology has the advantages of simple implement process and high transmission rate, the attribute-based encryption technology can be used for realizing the resource access control of fine grains under a cloud calculation environment, and a lot of overhead is saved for an attribute authority and a user.
Description
Technical field
The present invention relates to a kind of encryption technology, particularly relate to a kind of encryption technology based on attribute of safe outsourcing.
Background technology
In the last few years, along with the development of network, the rises of appearing vividly such as social networks, ecommerce, digital city and Online Video.These emerging technology need the support of large storage and high-performance server, but need a large amount of manpowers and expensive material resources to the maintenance of this server.Future addresses this problem, and the computer network giants such as GOOGLE, Amazon in 2006, put forward the conception of cloud computing.Cloud computing, as a great innovation of information industry, has more and more received approval and the extensive concern of society and academic all circles.But the problem of thing followed information security hidden danger and the requirement of the high operating load ability of server also be can not be ignored.
Summary of the invention
The object of the present invention is to provide that a kind of implementation process is simple, efficiency of transmission is high, can be used for realizing cloud computing environment under fine-grained resources accessing control, save the encryption technology based on attribute of the safe outsourcing of a large amount of expense for attribute authority (aa) mechanism and user.
Technical scheme of the present invention is: comprise the steps:
1) system establishment step;
2) outsourcing secret generating initialization step;
3) external key generation step;
4) internal key generation step;
5) transition key blinds step;
6) encrypting step;
7) part decryption step;
8) complete decryption step.
The invention process process is simple, efficiency of transmission is high, can be used for realizing cloud computing environment under fine-grained resources accessing control, for attribute authority (aa) mechanism and user save a large amount of expense.
