| Research Abstract |
We made security analyses of two efficient cryptographic primitives : stream ciphers to keep confidentiality and hash functions to keep integrity. We also designed authenticated data structures with confidentiality, which can be constructed using these cryptographic primitives, and confirmed their efficiency and security. The results are useful to make secure and reliable responses efficiently to queries on a large amount of information. An example of applications is outsourcing of database services using clouds.
