Description: RSA算法的原理分析及实现。RSA是既能用于数据加密也能用于数字签名的一种非对称密码体制的算法。它有一对密钥，其中之一是私有密钥，由用户保存；另一个为公开密钥，可对外公开。并用VC++语言实现，通过MFC设计的一个小系统来模拟算法的简单应用-RSA algorithm and the realization of the principle. RSA is the best tool for data encryption can be used for digital signatures, a non-symmetric cryptography algorithms. It has a pair of keys, one of which is the private key, by the user preserved another for the public key can be made public. And VC++ Language, through the MFC designed a small system to the simple application of simulation algorithm Platform: |

Description: Security in wireless sensor networks is currently provided
through symmetric key cryptography. Although the low
computational complexity involved in private key algorithms is
advantageous, session keys must be embedded in the sensor nodes
before the nodes can be deployed. Protocols are also necessary to
ensure synchronization of keys between the devices on a network.
These protocols require significant communication and storage
overhead. The limitation of such a cryptosystem is that it is not
possible to guarantee the confidentiality of the session keys Platform: |

Description: While cryptography can still be a controversial topic in the programming community, Java has weathered that storm and provides a rich set of APIs that allow you, the developer, to effectively include cryptography in applications-if you know how.
This book teaches you how. Chapters one through five cover the architecture of the JCE and JCA, symmetric and asymmetric key encryption in Java, message authentication codes, and how to create Java implementations with the API provided by the Bouncy Castle ASN.1 packages, all with plenty of examples. Building on that foundation, the second half of the book takes you into higher-level topics, enabling you to create and implement secure Java applications and make use of standard protocols such as CMS, SSL, and S/MIME.-While cryptography can still be a controversial topic in the programming community, Java has weathered that storm and provides a rich set of APIs that allow you, the developer, to effectively include cryptography in applications-if you know how.
