The cryptographic keys are usually derived from a password. Thus, password based key derivation function (PBKDF) is the core of the security scheme. However, the security of the PBKDF of Office is not yet ensured. In this paper, the PBKDF algorithm is analyzed through the game-playing approach and upper bounded of the Adversary's Advantage over the KDF and random function. Based on that, we discussed the practical safety of the Office encrypted files, and show that Office is secure when the user password is longer than 6 characters.","PeriodicalId":408223,"journal":{"name":"Anti-counterfeiting, Security, and Identification","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127843053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

And with the development of wireless technologies, the application of the WBAN has expanded to entertainment, leisure, military and other fields. So far, IEEE 802 Task Group has published a new IEEE 802.15.6 standard. The standard defines a Medium Access Control (MAC) layer supporting three Physical (PRY) layers. The three PRY layers are narrowband (NB) PRY, ultra wideband (UWB) PRY and human body communication (RBC) PRY. In this paper, the concept and applications of WBAN are introduced; comparisons between 802.11, 802.15.1, 802.15.4 and 802.15.6 are made; and a brief description about the three PRY layers specifications is given. Some existing questions and challenges the WBAN confronts are also analyzed.","PeriodicalId":408223,"journal":{"name":"Anti-counterfeiting, Security, and Identification","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126720636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The TCP/UDP hybrid stream's transmission delay would increase significantly, that always generate failure of TCP stream transmitting. This paper proposes an improved IEEE 802.11 DCF protocol and theory model based on TCP/UDP hybrid streams. The improved protocol mentioned differentiates length between TCP package and UDP package, and adaptively adjusts MAC frame length, which avoids lost packages retransmission and delay from TCP/UDP hybrid stream. The simulation we made to verify that prior estimate for TCP/UDP packages quantities in sole channel can promote throughput of network more than 10% with transmission delay elimination.","PeriodicalId":408223,"journal":{"name":"Anti-counterfeiting, Security, and Identification","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121425726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

And we use ripple propagation patterns to model raindrops ripple. Compared to the traditional physical methods of water wave modeling, the 2D CVCNs could model the phenomena by an easier way.

The P-channel MOSFET on-resistance that connects the input and output is only 100mΩ in the circuit. In order to ensure the drop voltage from the input to the output is equal to V1(when I1 = 2A, V1 = 256mV), the circuit uses a high-gain amplifier to adjust the gate voltage of the P-channel MOS transistor(MP0). And the circuit also uses a high side current sensing comparator to limit the current that flows through the P-channel MOSFET. The maximum forward current achieves 2A, and the maximum reverse leakage current is 2μA. Simulation results using a 0.5μm BCD process are presented and discussed.","PeriodicalId":408223,"journal":{"name":"Anti-counterfeiting, Security, and Identification","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115962294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Gabor feature of image is used to detect the forged image caused by copy and move operations. The Gabor filter with different scaling factors, rotation angles and frequencies are considered to generate the Gabor feature representation of an image. For comparing two images, their Gabor features are applied to find if there is any similarity between them. To reduce the processing time and detect the small copy and move area, an image is divided into small blocks. In each block, it extracts a new descriptor and key points from the Gabor feature of the block image. Furthermore, the proposed method can also locate the duplicated regions precisely and detects the rotation angles and scale factors of the forged image. Experimental result shows that the proposed method can achieve high correct rate, estimated rotation angle and scaling factor. The proposed method has robustness and reliability.","PeriodicalId":408223,"journal":{"name":"Anti-counterfeiting, Security, and Identification","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124965466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
