No. of bitstreams: 1 68080200016.pdf: 1221107 bytes, checksum: 3659b943b5aa0225d675ecfffd80b843 (MD5) Previous issue date: 2011-04-28 / The Digital Signature on Foreign Exchange Contracts has appeared in 2004, and it is a process that emerges as an alternative to the traditional process of manual signature on contracts. This work intends, through a quantitative analysis of a Brazilian bank data base, search for behavior patterns that may exist in digitally signed foreign exchange operations, according with the size of companies and its segmentation in the Bank. The foreign exchange market concept will be analyzed, and also its structure and pattern in Brazil. The Digital Signature process will be deeply analyzed, showing concepts necessary for its correct work model, like cryptography, hash functions, digital certificates and public key infrastructure. As contributions of the study will be present the importance of the Digital Signature process at the present time, the growth and the relevance of small and medium companies using Digital Signature and the differences between the market segmentation of the companies. / A Assinatura Digital de Contratos de Câmbio, regulamentada em 2004, é um processo que surge como uma alternativa ao tradicional processo de assinatura manual nos contratos. Este trabalho pretende, através de análise quantitativa da base de dados de um grande banco no Brasil, verificar padrões de comportamento que podem existir nos registros de operações de câmbio assinadas digitalmente, de acordo com o porte da empresa e sua segmentação dentro do Banco. O conceito do mercado de câmbio será analisado, assim como sua estrutura e funcionamento no Brasil. A Assinatura Digital será analisada profundamente, apresentando conceitos imprescindíveis para este processo, como a criptografia, funções hash, certificação digital e infra-estrutura de chaves públicas. Como contribuições do estudo serão apresentadas a importância do processo de assinatura digital na atualidade, o crescimento e a relevância das pequenas e médias empresas no uso da assinatura digital e as diferenças relativas à segmentação das empresas.
