Modern cryptography exists at the intersection of the disciplines of mathematics , computer science , electrical engineering , communication science , and physics. Applications of cryptography include electronic commerce , chip-based payment cards , digital currencies , computer passwords , and military communications. Cryptography prior to the modern age was effectively synonymous with encryption , converting information from a readable state to unintelligible nonsense. The sender of an encrypted message shares the decoding technique only with intended recipients to preclude access from adversaries. The cryptography literature often uses the names Alice "A" for the sender, Bob "B" for the intended recipient, and Eve " eavesdropper " for the adversary.

## Analysis and Review of Encryption and Decryption for Secure Communication

Since that time, this paper has taken on a life of its own Does increased security provide comfort to paranoid people? Or does security provide some very basic protections that we are naive to believe that we don't need? During this time when the Internet provides essential communication between literally billions of people and is used as a tool for commerce, social interaction, and the exchange of an increasing amount of personal information, security has become a tremendously important issue for every user to deal with. There are many aspects to security and many applications, ranging from secure commerce and payments to private communications and protecting health care information.

The operation modes of block ciphers are studied and, as prominent examples for block ciphers, DES and AES are described. Asymmetric-Key Cryptography Public key cryptography is based on asymmetric cryptographic algorithms that use two related keys, a public key and a private key; the two keys have the property that, given the public key, it is computationally infeasible to derive the private key. Menu Symmetric-key cryptography 17 March on cryptography, security, Java. Working- The keys, in practice, represent a shared secret between two or more parties that can be used to maintain a private information link. Sicurezza dei Sistemi Informatici-G.

The Encryption service lets you encrypt and decrypt documents. When a document is encrypted, its contents become unreadable. An authorized user can decrypt the document to obtain access to the contents. If a PDF document is encrypted with a password, the user must specify the open password before the document can be viewed in Adobe Reader or Adobe Acrobat.

Стратмор наморщил лоб и прикусил губу. Мысли его метались. Он, конечно, с легкостью мог набрать код лифта и отправить Сьюзан домой, но она нужна ему. Она должна помочь ему найти ключ в компьютере Хейла.

Там происходит что-то очень серьезное. - Мидж.  - Он постарался ее успокоить, входя вслед за ней в комнату заседаний к закрытому жалюзи окну.  - Пусть директор разбирается .

- В трубке воцарилась тишина, и Джабба подумал, что зашел слишком.  - Прости меня, Мидж. Я понимаю, что ты приняла всю эту историю близко к сердцу. Стратмор потерпел неудачу.

Черт возьми, Мидж! - взорвался Джабба.  - Я сказал, что вируса в шифровалке. Тебе надо лечиться от паранойи. В трубке повисло молчание. - Мидж… - Джабба попробовал извиниться.

Сзади щелкнул взведенный курок беретты. - Отпусти ее, - раздался ровный, холодный голос Стратмора. - Коммандер! - из последних сил позвала Сьюзан.

Я все это видел, потому что прятался в подсобке. Чатрукьян хотел вызвать службу безопасности, что разрушило бы все планы Стратмора. Ну и ловок, подумала Сьюзан. На все у него готов ответ.
