The Internet Security Lab is in the School of Computer and Communication Engineering at University of Science and Technology Beijing. We often collaborate with members of the cryptography group in the near universities at ZhongGuanCun as well.

Research projects in the group focus on various aspects of network and computer security. In particular the lab focuses on applications of cryptography to real-world security problems. For more information follow the links below.


Group-Based Cryptography

Group-based cryptography is a new cryptographic technology that address the problems of secure resource sharing, communciation, authentication, and key management in a large group. Our research fouces on the basic cryptographic problems: Cryptographic repressentation of subsets, Predicate-based encryption, Verificable Random Function.

Following links are Demo of relative algorithm:

① Indentity-set-based Ecnryption (SBE) SBE_Demo

② Attribute-set-based Encryption (ASBE) ASBE_Demo

  ASBE XML version XML_ASBE_Demo

③ DesignatedVerifier-Set Signature(DVSS) DVSS_Demo

④ The practical application of ASBE: Application_Demo

 


Encrypted Email System  Demo

Content privacy of Email is making more and more attention in the recent years. Our objective is to built a real practical Email cryptosystem by using every people in Internet. Its most significiant feature is easy to use. Our research includes our own algorithms, some Demos and patent.

Cloud Platform and Security

Cloud Computing is a new computing model after Client/Server model and Browser/Server model. In our lab, we have built a small cloud enveriment, including CloudStack and OpenStack. Based on these two framework, our research fouces on secure data sharing and message exchange, blind audit in the Cloud.

 


Secure multi-party computation

Secure multi-party computation (SMC) is to solve a group of mutual distrust in between protection of privacy of collaborative computing problem, SMC to ensure that the input of independence, the correctness of the computation, without revealing the input value to participate in the calculation of the other members.

 


Secure Blockchain: Shellchain Demo

A blockchain is a distributed database that maintains a continuously growing list of ordered records called blocks. Each block contains a timestamp and a link to a previous block. By design, blockchains are inherently resistant to modification of the data — once recorded, the data in a block cannot be altered retroactively.

Students' Projects

WiFi Attack

We research the WEP and WPA which are widely used as Wired Equivalent Privacy Protocol. Our research fouces on the Protocol loopholes, in this way, we can access wireless router without authorization.

 


Android card recognition and cloud management system

Our products realize the paper card identification, the identification and generation of two-dimensional code cards, and the business card information stored in the contact. NFC tags for writing and reading. About the cloud management system as yet to be learning and development.
