标准模型下具有IND-CCA2安全的混合加密方案
Hybrid encryption scheme with IND-CCA2 secure in standard model
摘要
Abstract
This paper improved the classical generating trapdoor algorithm based on a variant of ideal-SIS(ideal small integer solution)by Damien Stehle.What’s more,the new scheme improved a chosen-plaintext attacks security scheme by Damien Stehle .Then,combining with SWIFFT compression functions,it designed an indistinguishable against adaptive chosen-cipher-text attacks secure hybrid encryption scheme in the standard model.In this process,the new scheme required n log q less de-scription bit.It could process string from n log q bit to m ×n log q bit in the encryption and decryption processing.There is a huge improvement in key size and speed for these schemes.关键词
