In this paper, we study the problem of single database private information retrieval, and present schemes with only logarithmic server-side communication complexity. Previously th...
The common perception of public key cryptography is that it is complex, slow and power hungry, and as such not at all suitable for use in ultra-low power environments like wireless...
Symmetric-key block ciphers encrypt data, providing data confidentiality over the public Internet. For inter-operability reasons, it is desirable to support a variety of symmetric...
Web services security specifications are typically expressed as a mixture of XML schemas, example messages, and narrative explanations. We propose a new specification language fo...
We describe a protocol design process, and illustrate its use by creating ATSPECT, an Authentication Test-based Secure Protocol for Electronic Commerce Transactions. The design pr...
