    Echoes From the Void: Detecting DNS Tunneling With Blackhole Features in Encrypted Scenarios With High Accuracy by Wafa S. Alorainy

    Published 2025-01-01
    “…A five-fold cross-validation with a random forest classifier achieved 99.9% classification accuracy, a 99.9% F1 score, and 100% precision and recall. Feature importance analysis indicates that blackhole-related features contribute to the detection query-to-blackhole ratios (Gini importance of 0.35) and inter-blackhole intervals (0.20), which help focus on stealthy tunneling behavior. …”

    Analysis of super-long and sparse feature in pseudo-random sequence based on similarity by Chun-jie CAO, Jing-zhang SUN, Zhi-qiang ZHANG, Long-juan WANG, Meng-xing HUANG

    Published 2016-10-01
    “…Similarity analysis of pseudo-random sequence in wireless communication networks is a research hotspot problem in the domain of information warfare.Based on the difficulties in super-long sequence,extremely sparse feature,and futilities in engineering application for real-time processing exist in similarity analysis of sequence in wireless net-work,a method of similarity analysis of sequence in a certain margin of misacceptance probability was proposed.Firstly,the similarity probability distribution of real-random sequence was theoretically analyzed.Secondly,according to the standard of NIST SP 800-22,the randomness of pseudo-bitstream was analyzed and the validity of pseudo-bitstream was judged.Finally,similarity was analyzed and verified by combining super-long pseudo-random sequence in real wireless communication networks.The results indicate that the lower bound of similarity value is 0.62 when misacceptance prob-ability uncertainty at about 1%.Above conclusion is considerable importance from the significance and theoretical values in network security domains,such as protocol analysis,traffic analysis,intrusion detection and others.…”

    Clinical features and prognostic analysis of AKI in the internal medicine departments by XUE Xian, TANG Xiao-jing, ZHANG Di, SHEN Ai-wen, MEI Chang-lin

    Published 2018-01-01
    “…Objective To explore the clinical features of patients with acute kidney injury(AKI)in the internal medicine departments.Methods The kidney function indexes of the internal medicine patients were collected in Shanghai Changzheng Hospital from 2011 to 2012.According to the AKI diagnostic criteria of KDIGO in 2012,we screened out the AKI patients who met the criteria.By retrospectively studying their clinical data,we analyzed and summarized their clinical characteristics and the factors affecting the prognosis.Results From January 2011 to December 2012,there were a total of 33 332 cases of internal medicine patients in our hospital and 245 of them met the criteria of AKI.The incidence of AKI was 0.74%in internal medicine departments while the detection rate of AKI was 35.92%.The proportions of patients with AKI stage 1 to 3 were 42.45%,20.41% and 37.14%,respectively.Among all the internal medicine departments,patients in the department of nephrology accounted for 33.47%,followed by the department of cardiology(20.00%),gastroenterology(11.84%)and infectious disease(10.61%).The incidence of AKI from high to low was infection disease department(1.70%),nephrology department(1.37%),and cardiology department(1.11%).Of all the hospitalized patients with AKI,71.84% discharged with a better health condition and the kidney function discovered in only 34.69% of the discharged patients;28.16% died or gave up treatment.The most common departments with high fatality rate were the department of infectious disease(21.74%),gastroenterology and cardiology.Infection was the main cause of the AKI in internal medicine departments.Logistic regression analysis showed that higher AKI stage,more AKI risk factors,combination with liver disease or tumor were risk factors for death and giving up treatment,while chronic kidney disease was the protective factor.ConclusionsAKI is common in internal medicine system,with a high mortality rate and a higher recognition rate than perioperative AKI.Except for the department of nephrology,cardiology,departments of infectious disease and gastroenterology have heavy burden of AKI.The advanced stage of AKI,more risk factors,and comorbidities such as liver disease or tumor were associated with poor prognosis.…”
