Differential fault attack on lightweight block cipher Klein
Published 2016-10-01“…As a lightweight block cipher algorithm based on SP structure,Klien has the characteristics of high efficiency and low energy consumption.By analyzing the S-boxes differential propagation path,it was found that under the condi-tion of same input and different difference,the intersection elements were unique,which fall in the intermediate state set corresponds to output difference,and a differential fault attack scheme was proposed.By injecting two different faults in the last round of the algorithm,all the keys of the Klein algorithm can be recovered,and the complexity is negligible.This method can be promoted to other block cipher algorithms based on SP structure and Feistel structure.…”

Attack signature generation by traceable dynamic taint analysis
Published 2012-05-01“…Most of known attack signature generation systems took either black-box method or white-box method,both of which were limited in several aspects,such as costing a long time to capture sufficient samples,demanding arduous manual analysis and requiring source code of the vulnerable program.An attack signature generation method based on an innovative traceable dynamic taint analysis framework was proposed.By monitoring the vulnerable process execution,the executing trace and the constrain conditions exactly related to input data exploiting the vulnerability was extracted.Finally,by restoring the execution context and supplementing the determinant statements an executable Turing machine signature was attained.A prototype system was implemented and evaluated with different attack samples,which proved that the proposed method was able to generate accurate attack signature fast.…”

Label flipping adversarial attack on graph neural network
Published 2021-09-01“…To expand the adversarial attack types of graph neural networks and fill the relevant research gaps, label flipping attack methods were proposed to evaluate the robustness of graph neural network aimed at label noise.The effectiveness mechanisms of adversarial attacks were summarized as three basic hypotheses, contradictory data hypothesis, parameter discrepancy hypothesis and identically distributed hypothesis.Based on the three hypotheses, label flipping attack models were established.Using the gradient oriented attack methods, it was theoretically proved that attack gradients based on the parameter discrepancy hypothesis were the same as gradients of identically distributed hypothesis, and the equivalence between two attack methods was established.Advantages and disadvantages of proposed models based on different hypotheses were compared and analyzed by experiments.Extensive experimental results verify the effectiveness of the proposed attack models.…”

Power analysis attack of HMAC based on SM3
Published 2016-05-01“…The current power analysis attack of HMAC based on SM3 applies only to the object,on which there is the Hamming weight and Hamming distance information leakage at the same time.there is only a single information leakage mode on the attack object,then the attack methods don't work.To solve the limitations of the current attack methods,a novel method of the power analysis attack of HMAC based on SM3 was proposed.The different attack object and their related va-riables were selected in each power analysis attack.The attacks were implemented according to the Hamming distance mod-el or Hamming weight model of the intermediate variables.After several power analysis attacked on the first four rounds of SM3,the equations that consists of the results proposed of all the power analysis attacks were obtained.The ultimate attack object is derived by getting the solution of the equations.The experimental results show that the oposed attack method was effective.The method can be used universally because its being available for both the situation of co-exist of hamming weight with Hamming distance,and that of either the Hamming weight or choosing the Hamming distance model existence.…”

Defense scheme for the world state based attack in Ethereum
Published 2022-04-01“…Ethereum is taken as the representative platform of the second generation of blockchain system.Ethereum can support development of different distributed applications by running smart contracts.Local database is used to store the account state (named world state) for efficient validation of transactions, and the state root is stored in the block header to guarantee the integrity of the state.However, some researches revealed that the local database could be easily tempered with, and attackers can issue illegal transactions based on the modified account state to obtain illegitimate benefits.This world-state based security problem was introduced, and the preconditions for attack were analyzed.Compared with the two common security threats under the PoW (proof of work) consensus, it was found that when the attacker controls the same mining computing power, the world-state based attack brought higher risk, and the success rate approached 100%.In order to deal with this threat, a practical scheme for attack detection and defense was proposed accordingly.The secondary verification and data recovery process were added to the Ethereum source code.The feasibility and complexity of the proposed scheme was evaluated with single-machine multi-threading experiments.The proposed scheme improves Ethereum’s tolerance to malicious tampering of account state, and is applicable to other blockchain platforms applying local database for transaction validation, such as Hyperledger Fabric.In addition, the time and computational overhead brought by the proposed scheme are not prominent, so it has good applicability and induces acceptable impact on the performance of original system.…”

Therefore, we propose a local perturbation based adversarial attack method for object detection localization, which identifies key areas affecting target localization and adds adversarial perturbations to these areas to achieve bounding box attacks on target bounding box localization while ensuring high stealthiness. …”

Blind mask template attacks on masked cryptographic algorithm
Published 2019-01-01“…Masking is a countermeasure against differential power analysis (DPA) attacks on cryptographic devices by using random masks to randomize the leaked power of sensitive information.Template attacks (TA) against cryptographic devices with masking countermeasure by far require attackers have knowledge of masks at the profiling phase.This requirement not only increase the prerequisite of template attacking,but also lead to some sort of difference between the experimental encryption codes of the profiling device and the codes of commercial cryptographic devices,which might degrade performance in real world attacking.Blind mask template attack directly learns templates for the combination of no mask intermediate values without the need of knowing the masks of training power traces,and then uses these templates to attack masked cryptographic devices.Both traditional Gaussian distribution and neural network were adopted as the templates in experiments.Experimental results verified the feasibility of this new approach.The success rate of neural network based blind mask template attacking against masked cryptographic devices is very close to that of traditional template attacks against cryptographic devices without masking countermeasure.…”
