Cryptography embodies the mathematical principles, means, and methods for the transformation of data in order to hide its information content, prevent its undetected modification, and/or prevent its unauthorized use.

Security services in cryptography ppt. 20 cryptography, being an art of encrypting and decrypting confidential information and private messages, should be implemented in the network security to prevent any leakage and threat. Various cryptography techniques has been developed to provides the data security, to ensures that the data transferred between communication parties are confidential, not modified by unauthorized party, to prevent hackers from accessing and using their information. It allows users to conveniently and securely access shared cloud services, as any data that is hosted by cloud providers is protected with encryption.

Cryptography is the practice and the study of concealing the information and it furnishes confidentiality, integrity, and exactness. Not on the chance of his not attacking, but rather on the fact that we have made our position unassailable. Cryptography is the science of writing or reading coded messages.

Cryptography fits into the cia triad, as it can be used to ensure confidentiality and integrity of a message. Focusing on the fundamental principles that ground modern cryptography as. A service provided by a protocol layer of communicating open systems, which ensures adequate security of the systems or of data transfers rfc 2828 defines it as:

It can be done by using any of these techniques discussed above for fortifying the personal data transmission as well as for secure transaction. | powerpoint ppt presentation | free to view The following subsections summarize some key security services and mechanisms.

There are many aspects to security and many appli cations,. Cryptography is used to defend the data and to defend the data and to define it in the simple and easy words, it is an art of writing and solving the codes. This book presents a comprehensive introduction to the role that cryptography plays in providing information security for technologies such as the internet, mobile phones, payment cards, and wireless local area networks.
