The moment overseas convention on utilized Cryptography and community safety (ACNS 2004) used to be subsidized and arranged via ICISA (the foreign Communications and data defense Association). It was once held in Yellow Mountain, China, June 8–11, 2004. The convention lawsuits, representing papers from the tutorial song, are released during this quantity of the Lecture Notes in machine technology (LNCS) of Springer-Verlag. the world of analysis that ACNS covers has been gaining significance in recent times as a result of improvement of the web, which, in flip, implies worldwide publicity of computing assets. Many ?elds of study have been coated via this system of this song, provided during this lawsuits quantity. We think that the papers herein certainly re?ect the cutting-edge in defense and cryptography study, all over the world. this system committee of the convention obtained a complete of 297 submissions from around the globe, of which 36 submissions have been chosen for presentation throughout the educational song. as well as this music, the convention additionally hosted a technical/industrial tune of shows that have been rigorously chosen in addition. All submissions have been reviewed by way of specialists within the proper areas.

Get Securing Converged IP Networks: New Requirements for ICT PDF

Info and conversation expertise (ICT) networks fluctuate from IT networks simply because they mingle information resources with resources comparable to voice, leisure, media, actual defense, and extra. IP convergence represents either a brand new enterprise principal and a essentially new safety paradigm. the continued shift in industry terminology from IT to ICT exhibits the conclusive acceleration of IP convergence.

Example text

We assume there are keyword fields associated with each document. If documents were emails for example, we might define the following 4 keyword fields: “From”, “To”, “Date” and “Subject”. For simplicity, we make the following assumptions: We assume that the same keyword never appears in two different keyword fields. The easiest way to satisfy this requirement is to prepend keywords Secure Conjunctive Keyword Search over Encrypted Data 35 with the name of the field they belong to. Thus for example, the keyword “From:Bob” belongs to the “From” field and can not be confused with the keyword “To:Bob” that belongs to the “To” field.

The threshold Paillier scheme defined in [10] can be easily modified to use additive shares of the secret key over integers (as this implies shares over and thus with the modification given above, satisfies the properties required for The unmodified Pailler cryptosystem satisfies the requirements for Zeroknowledge proofs of plaintext knowledge are given in [7]. 3 System Model We denote by the number of servers, and the maximum number that may be corrupted. Privacy of the protocols is preserved if Assuming the servers may use a broadcast channel to communicate, every answer returned to a client will be correct if or all servers are honest-but-curious.

This can be trivially achieved by sending the entire database to the client, so PIR mandates sublinear (and ideally polylogarithmic) communication complexity as a function of Our approach relaxes this requirement for server-to-server communication (which is not typically employed in PIR solutions), and retains this requirement for communication with clients; our approach ensures client communication complexity that is independent of In addition, classic PIR does not address database changes and does not support labelled data on which clients can search.
