THEORY AND PRACTICE OF SECRET DATA IN COMMUNICATION USING CRYPTOGRAPHY

Information Technology

Securing the information is becoming a key consideration when communicating across a network in the modern world of communication. Users frequently trade sensitive information and documents when communicating. Security is therefore a key factor in communication. Communication and security go hand in hand. It is commonly acknowledged that the architecture of future IT systems will be heavily influenced by data security. Numerous of these IT applications will be implemented as embedded systems that largely rely on security measures. Examples include copy protection systems for audio/video consumer items, wireless computing, pay-TV, wireless phone security, and digital theatres. Keep in mind that a sizable portion of those embedded applications will be wireless, making the communication channel particularly weak. Cryptography is the study of secure communication techniques that allow only the sender and intended recipient of a message to view the content. It is a type of a rule or a technique by which private or sensitive information is secured from the public or other members. It focuses on the confidential data, authentication, data integrity etc. It is a field of computer science and mathematics which focuses on techniques for secure connection between two parties while a third party is present. It is based on methods like encryption, decryption, signing, etc.
