It also explains what is Encryption and Decryption. a) Cryptography basics (00:21):http://youtu.be/BEb_AnPWPwY?t=21s how do we provide this security during transmission? Well, One way of ensuring security can be use of CRYPTOGRAPHY! Cryptography is a field of network security which deals with hiding "real" infromation when it is under transmission between the two parties. Usually, the real information is transformed or hidden into another message and transmitted over the network. This transformed message in itself will make no sense even if any hacker gets hold of this information. When it reaches the destination, the receipent will know a method to de-transform the garbage message into the original information which the sender had sent.method of transforming message at sender's side and de transforming at reciever's side forms the basic model of Cryptography. b) Encryption and Decryption (3:57):http://youtu.be/BEb_AnPWPwY?t=3m57s First, the information to be transmitted, called as plain text(or message) is fed to an Encryption system. The Encyrption system uses a key to convert the plain text to encyrpted form which looks like garbage value. This is also called as cipher text. A corresponding key is used at the other end to decrypt the cipher text back to original message. When we say a key, it actually means a piece of string value which is fed to encyprtion and decryption algorithms along with the text for transformation. When the message reaches the destination, this system at the other end decrypts the cipher text into original message with the help of the key. This is called as Decryption System. The output of the Decryption System is the intended message. Depending on how the keys are shared, we can classify crytography as symmetric and asymmetric. If the keys used by both parties are same, then it is called symmetric key cryptography, or private key cryptography. If both parties use different keys for encyrption and decryption, then it is called asymmetric key cryptography or public key cryptography. video URL : https://www.youtube.com/watch?v=BEb_AnPWPwY Watch ALL CN VIDEOS: https://www.youtube.com/playlist?list=PL9OIoIp8YySF4mkIihOb_j2HZIRIlYuEx For more, visit http://www.EngineeringMentor.com Facebook: https://www.facebook.com/EngineeringMentor Twitter : https://twitter.com/Engi_Mentor

What is CRYPTO CLOUD COMPUTING? What does CRYPTO CLOUD COMPUTING mean? CRYPTO CLOUD COMPUTING meaning - CRYPTO CLOUD COMPUTING definition - CRYPTO CLOUD COMPUTING explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Cloud computing is a combination of IaaS, PaaS, SaaS. To construct a secure cloud computing system, security at infrastructure, service platforms and application software levels have to be studied for a secure cloud computing system. Information encryption is one of effective means to achieve cloud computing information security. Traditionally, information encryption focuses on specified stages and operations, such as data encryption. For cloud computing, a system level design has to be implemented. Crypto cloud computing is a new secure cloud computing architecture. It can provide protection of information security at the system level, and allows users access to shared services conveniently and accurately. Crypto cloud computing protects individual’s connections with the outside world. It can protect the personal privacy without any delay of information exchange. Crypto cloud computing is based on the Quantum Direct Key system. Quantum Direct Key (QDK) is a set of advanced asymmetric offline key mechanism. In this mechanism, all entities get public and private key pair according to their ID. Each entity only holds its own private key, but has a public key generator to generate any public key. In this system, an entity can produce the public key of any other entities offline, no any third-party agency (such as CA) is necessary. Crypto cloud computing based on QDK can avoid network traffic congestion, and other drawbacks using current encryption system. In the crypto cloud computing system, each entity encrypts data using his/her own private key. All elements in the system such as cloud computing infrastructure units, platform, virtualization tools and all involved entities have their own keys. While fulfilling their own functions of information exchange and processing, all these elements will use the public key and private key to perform authentication first. What’s more, events occur in the cloud computing are also assigned a unique key. In this way, crypto cloud system guarantees the security and credibility of information exchange. Current cloud computing structure is developed for data and computing sharing. Security is not priority of system. On the contrary, encryption and security are inherently integrated in the crypto cloud computing based on the QDK. QDK authorized function units are bricks of crypto cloud computing. Besides primary function of data en/decryption, crypto cloud computing also provides many security related functions. For example, all channels sign transmit data using with their own keys, and the receiving terminals can avoid hijacking by verifying signature. What’s more, the exact position of security leakage can be identified determined by analyzing digital signatures of forged data. Based on such capabilities, crypto-related functions can be provided as services in cloud, which is named as ‘Crypto as a service (CAAS)’. Crypto cloud computing is not only the advances in information technology, but also innovation of logical relationship. In crypto cloud computing system, non-system data is not allowed to store and transmit. Private Key and offline public key, play a role of identification and certification in the process of information exchange. In this way, the cloud establishes a relationship of trust with a customer. Data identification depends on the logical relationship of mutual trust or need, and the logical relationship depends on the cloud customer. Crypto cloud computing is a new framework for cyber resource sharing. It protects data security and privacy. Well, in cloud environment, crypto cloud computing guarantees the information security and integrity during whole procedure. Security management of cloud computing can also be performed by authorizing the signatures of every element involved. What’s more, a user can retrieve all related resources using his QDK key. There is no personal privacy under the current cloud framework, as pointed out by Mark Zuckerberg, 'the Age of Privacy Is Over '.However, with the development of crypto cloud computing, we can resolve the conflict between services data sharing and privacy security. It opens up new prospects for the development of information sharing technology.
