AES side channel attack protection using random isomorphisms
General method of side-channel attacks protection, based on random cipher isomorphisms is presented. Isomorphic ciphers produce common outputs for common inputs. Cipher isomor-phisms can be changed independently on transmitting and receiving sides. Two methods of RIJNDAEL protection are considered. The first one is based on random commutative isomor-phisms of underlying structure. The set of fi...
متن کاملOn-Demand Time Blurring to Support Side-Channel Defense
Side-channel attacks are a serious threat to multi-tenant public clouds. Past work showed how secret information in one virtual machine (VM) can be leaked to another, co-resident VM using timing side channels. Recent defenses against timing side channels focus on reducing the degree of resource sharing. However, such defenses necessarily limit the flexibility with which resources are shared. In...
متن کاملHigh-Resolution Side-Channel Attack Using Phase-Based Waveform Matching
This paper describes high-resolution waveform matching based on a Phase-Only Correlation (POC) technique and its application for a side-channel attack. Such attacks, such as Simple Power Analysis (SPA) and Differential Power Analysis (DPA), use a statistical analysis of signal waveforms (e.g., power traces) to reduce noise and to retrieve secret information. However, the waveform data often inc...
متن کاملPower Analysis Based Side Channel Attack
Side channel attacks break the secret key of a cryptosystem using channels such as sound, heat, time and power consumption which are originally not intended to leak such information. Power analysis is a branch of side channel attacks where power consumption data is used as the side channel to attack the system. First using a device like an oscilloscope power traces are collected when the crypto...
متن کاملSide-channel attack on labeling CAPTCHAs
We propose a new scheme of attack on the Microsoft’s ASIRRA CAPTCHA which represents a significant shortcut to the intended attacking path, as it is not based in any advance in the state of the art on the field of image recognition. After studying the ASIRRA Public Corpus, we conclude that the security margin as stated by their authors seems to be quite optimistic. Then, we analyze which of the...
