  • Protecting Web usage of credit cards using One-Time Pad cookie encryption
    Proceedings - Annual Computer Security Applications Conference ACSAC, 2002
    Co-Authors: Donghua Xu, Chenghuai Lu, Andre Dos Santos
    Abstract:

    The blooming e-commerce is demanding better methods to protect online users' privacy, especially the credit card information that is widely used in online shopping. Holding all these data in a central database of the Web sites would attract hackers' attacks, impose unnecessary liability on the merchant Web sites, and raise the customers' privacy concerns. We introduce and discuss in detail the secure distributed storage of sensitive information using HTTP cookie encryption. We are able to employ One-Time Pads to encrypt the cookies, because encryption and decryption are both done by the server, which is an interesting characteristic overlooked by the existing systems. We implemented this protocol and showed that it is simple, fast and easy to program with.

  • Encrypting Wireless Communications On the Fly Using One-Time Pad and Key Generation
    IEEE Internet of Things Journal, 1
    Co-Authors: Guyue Li, Zheying Zhang, Junqing Zhang, Aiqun Hu
    Abstract:

    The one time Pad (OTP) secure transmission relies on the random keys to achieve perfect secrecy, while the unpredictable wireless channel is shown to be a good random source. There is very few work of the joint design of OTP and key generation from wireless channels. This paper provides a comprehensive and quantitative investigation on secure transmission achieved by OTP and wireless channel randomness. We propose two OTP secure transmission schemes, i.e., Identical Key-based Physical-layer Secure Transmission (IK-PST) and Un-identical Key-based Physical-layer Secure Transmission (UK-PST). We quantitatively analyze the performance of both schemes and prove that UK-PST outperforms IK-PST. We extend the pairwise schemes to a group of users in networks with star and chain topologies. We implement prototypes of both schemes and evaluate the proposed schemes through both simulations and experiments. The results verify that UK-PST has a higher effective secret transmission rate than that of IK-PST for scenarios with both pairwise and group users.
