In the DAS model, the conventional scheme for query over encrypted data in database is to construct efficient index in database. This can ensure query efficiency. However, the fuzzy search is often used in the query of character data. It will be very tough owing to data encryption. Even the tiny changes of plaintext, the ciphtext will be quite distinct. Therefore, it is crucial to construct efficient index of encrypted character strings. To address these problems, a cryptographic scheme of character data in relational database is proposed in this paper. In this scheme, the char or varchar data type and clob data type will be considered respectively. For the data of char or varchar type, an index based double filtration is established. The index includes two parts: the first part of index is used to determine the set of existed characters in original string, and the second part stores the characteristic value of the characters' positions. The first part of index implements the first filtration, which will filter all the records include inaccurate characters. The second part of index is used to verify the positions of character strings. It's the second filtration. For the data of clob type, instead of the original character data, the positions of all the character strings will be stored. This scheme avoids needless decryption and data transfer. Consequently, better query efficiency is achieved and fuzzy search is well supported.","PeriodicalId":403283,"journal":{"name":"2010 International Conference on Networking and Digital Society","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131908650","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}

In this paper, a network performance analysis approach based on correlation analysis and regression analysis is presented which focusing on solving the difficult problem that general diagnosis algorithms can hardly build for CDMA network optimization. Based on the characteristic of performance indexes, the statistical method was introduced to performance optimization. The correlation coefficients and degree of curve fitting were proposed to measure the related degree between performance indexes, which is the foundation of fault diagnosis for engineers.

Since it was introduced in 1996, many variants of proxy signature schemes have been proposed. Among of them, the requirement of proxy signer's privacy protection and the revocation of proxy signer's anonymous identity are needful in some practical applications. Recently, Wang et.al gave a new signature type: proxy ring signature with revocable anonymity. It allows that proxy signer anonymously produces a proxy signature. However, it is anonymous for the others except that the original signer can know exactly who is the actual proxy signer. Unfortunately, in this paper, by analyzing the scheme, we show that the scheme does not satisfy anonymity, that is to say, given an anonymous proxy signature, the others also can know the actual identity of proxy signer beside original signer. At the same time, it cannot also revoke anonymity of proxy signer's identity. Finally, we give the corresponding attacks on the scheme and the reasons to produce suck attacks.","PeriodicalId":403283,"journal":{"name":"2010 International Conference on Networking and Digital Society","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126743132","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}
