A Comparative study of Forward Secure Publickey Method Using HIBE and BTE
Journal Title: International Journal on Computer Science and Engineering - Year 2010, Vol 2, Issue 4
Abstract
T h e threat of key exposure becoming more acute as yptographic computations are performed more frequently on poorly protected devices (smart-cards, mobile phones, even PCs), new techniques are needed to deal with this concern. One promising approach which we focus on here is to onstruct forward secure cryptosystems. The existence of non-trivial, orwardsecure public-key encryption (PKE) schemes,however, has been open .Forward-secure PKE has the obvious practical advantage that a compromise of the system does not mpromise the secrecy of previouslyencrypted information; it is thus appropriate for devices operating in insecure vironments. Furthermore, using such a scheme enables some measure of security against adaptive adversaries who may choose which parties to corrupt based on information learned in the course of a given protocol. We presented in this paper variant of scheme with better complexity; in particular, the publickey size and the key-generation/key-update times are independent of N . We suggested a method to achieve chosen ciphertext security for HIBE schemes using the CHK transformation . The resulting schemes are elective-ID chosen-ciphertext secure without andom oracles, based on he BTE .
