Abstract

In mobile environments, data stored in nodes are subject to side-channel attacks such as power analysis, emitted signal, detected radiation, etc. In this work, we propose a leakage-resilient inner-product encryption that the decryption will succeed if and only if the decryption attribute vector (generate the token) meets the orthogonal encryption attribute vector (obfuscated encryption policy), that is, the match holds that the inner product of two vectors is zero.
