5 Ways to Measure the Quality of Your Crypto
Introduction
Cryptography is definitely become a more mainstream topic today. Almost every device in this world is connected to the internet and sharing information. At the same time of the increasing of number in the device, the number of sensitive data in the information shared between devices, application, and server is also increasing in a larger scale. That information must be protected, so that the sensitive data will remain private.
The dominance attack today is not just about Denial of Services or Viruses just like 10 or 15 years ago. The nowadays attack is becoming more a specific purpose like data theft, eavesdropping, getting access to sensitive data like credit card numbers, passwords or maybe an intellectual property in an enterprise, or elevating privileges like an insider want to get a higher level access or access higher level value of data in order to dispose it or sell it. The number of attack services is also increasing with cloud computing or mobile devices, we got a lot of applications in different devices. In addition, sensitive data become located in more and more locations so there are more potential weaklings to exploit in to it.

To defend this, the principle of layer security is still a choice. It is the application that run the business and that’s why there is a good mix between traditional tool and modern technology being applied in this area. When applying the layer of security, usually people make it based on risk, applying the highest level of protection to the most risky and most risky and valuable application. So what happening now is, the critical application (or the most risky and valuable) are performing cryptography in the form of encrypt...

After watch and listen to this seminar, my perspective to cryptography become more broaden. What I learned in class and what the reality is seems very different. From what I learned in class, cryptography seems very good in terms of securing the data (confidentiality) and doing digital signatures (authentication) which make it become almost impossible for hackers to know the data or information encrypted. But then, I don’t realize that the most important thing in the cryptography is the key itself. Although, it seems very hard to know and get the key, the hackers still manage to do it. And usually the hackers are insiders because insiders usually have more information than outsider, so that it become clear the insiders are the most dangerous intruders.

In the rapidly developing field of computer science, there is no more controversial issue than encryption. Encryption has become a highly contested issue with the broad use of global networks including the Internet. As more and more sensitive documents are being placed on computer networks, and trusted information is being sent from computer to computer throughout the world, the need for encryption has never been greater. However, the effects of encryption on our lifestyle and the government's role in encryption has been (and will continue to be) debated for years to come.
What is encryption? Encryption is a technological technique that protects and secures the transfer of plain text information between two sources through the use of the internet. This is done by rearranging the text using a mathematical algorithm that renovates the message into an indecipherable form, which can only be unlocked and translated with a use of a key. The strength of the encryption key is measured by its length, which is determined by the number of bits and by the type of encryption program.
Encryption: - Data encryption is the best way to reduce risks associated with misplaced, lost or stolen data.
Cryptography affects the individuals lives everyday. Cryptography is the act of writing or solving code. Cryptography has been around for thousands of years however it is a very young science as it hasn’t been studied for long. Cryptography affects the way everyday things are done and carried out.
Electronic progress has been miraculous, even exciting, but with it problems evolve. One of the greatest is the threat to people's personal privacy. The Automatic Teller Machine (ATM) was developed in the 1980's to give people an easier way to de posit and withdraw cash that they had in the bank. Everyone who has an account is assigned a secret PIN number, but someone in the bank has access to clients' financial records in the electronic database. Another type of new technology is the ele ctronic tolls used on the nation's highways. Drivers can pay tolls...
Data Encryption is from the cryptography science, which includes coding and decoding of message to protect the safety. Development computer technology makes the encryption even more complicated. The ability for people to break codes is increasing, so are the ability to guard the codes. Many encryptions are available now. They were developed by some hi-tech company and sold, or you can choose some free service. Actually, when you are using the web browsers, emails, or even the basic system, your information has been automatically encrypted.
According to the Webster dictionary, “cryptography is the practice and study of data encryption and decryption - encoding data so that it can only be decoded by specific individuals.” Crypto is derived from the Greek word kruptos, to hide, from kruptein, which means hidden and secret. In the old days, people attempted to withhold certain information as their private possession, and to hide the information from exposures to the public. There were many different methods they used in order to conceal this information, such as substituting part of the information by symbols, numbers or pictures for different reasons to protect their secrets. With the advancement of human intellects and modern computing powers, cryptosystems are invented as systems used to encrypt and decrypt data electronically. By deploying sophisticated mathematical algorithm into the process, it combines the original data with one or more a serial of numbers or strings of characters, as known as “keys” privately and solely owned by sender and/or recipient. Cipher text is generated as an end result of this process. The computer aided data encryption is much more accurate, efficient and reliable compared to the ancient methods.
Protecting data through cryptography from unauthorized eyes is a high priority for organizations that store personal information. Cryptography is the process of hiding the real meaning of a message through a pre-determined code that is only known to the person encrypting and decrypting a message. Different forms of cryptography can be seen in our everyday life from the word puzzle in daily newspapers to secretaries writing in short hand. Cryptography has been around since the time of the Egyptians and has made many advances through the years.
Computer science is a vast field that includes nearly everything relating to computers. Everyday there is information transmitted all over the Internet. Pictures are uploaded, transactions are made on thousands of online retail websites, and banking transactions take place everyday on the Internet. All of these transactions have created a need for secure communications. People wish to keep things like banking, medical, and political information from the eyes of unwelcome parties. This has created a need for cryptography. Cryptography is the science or study of the techniques of secret writing, especially code and cipher systems, and is used by everyone from the average citizen to the government and military.
Encryption converts a message in such as way that its contents are hidden from unauthorized readers. It is intended to keep messages and information as a secret. Plaintext, also known as clear text, is the plain or original message, which is has not yet been encrypted. Once the message is encrypted it is then called a cipher text. This process is obviously referred as encryption. The exact opposite process is called decryption. Encryption is the most successful way to attain data security. To read an encrypted file, you must have access to a secret key or password that enables you to decrypt it. Data encryption is a means of scrambling the data so that is can only be read by the person holding the key, a password of some sort. Without the key, the cipher cannot be broken and the data remains secure. Using the key, the cipher is decrypted and the data is returned to its original value or state. Each time one desires to encrypt data, a key from the 72,000,000,000,000,000 possible key variations, is randomly produced, and used to encrypt the data. The same key must be made known to the receiver if they ar...
In the world, where security breaches and information stealing occurs more frequently, a service offering a secure data storage is a significant factor of a security arrangement. Encryption is simply stated as the practice of systematic information scrambling, so that it can be unscrambled later [10]. Data encryption interprets data into a different form, or cryptograph, so that a person holding a secret key (i.e. a decryption key) or password can access that data. The encrypted data is known as cipher text, whereas the unencrypted data is termed as plaintext. Presently, encryption is considered as one of the most effective data security technique and is widely used by a number of organizations for the purpose of secure and reliable transmission of data containing secret information. Asymmetric encryption and Symmetric encryption are two main types of encryption techniques.
Cryptography is the study or science of techniques of secret writing and message hiding. Cryptography constitutes any method in which someone attempts to hide a message, or the meaning in some medium. One specific element of cryptography is encryption, which hides the data or information by transforming it into an undecipherable code. Encryption uses a specified key to perform the data transformation. The length of the key for the encryption
In this era when the Internet provides essential communication between tens of millions of people and is being increasingly used as a tool for security becomes a tremendously important issue to deal with, So it is important to deal with it. There are many aspects to security and many applications, ranging from secure commerce and payments to private communications and protecting passwords. One essential aspect for secure communications is that of cryptography. But it is important to note that while cryptography is necessary for secure communications, it is not by itself sufficient. Cryptography is the science of writing in secret code and is an ancient art; In the old age people use to send encoded message which can be understand by the receiver only who know the symbolic and relative meaning of that encoded message .The first documented use of cryptography in writing dates back to circa 1900 B.C. Egyptian scribe used non-standard hieroglyphs in an inscription. After writing was invented cryptography appeared spontaneously with applications ranging from diplomatic missives to war-time battle plans. It is no surprise, then, that new forms of cryptography came soon after the widespread development of computer communications. In telecommunications and data cryptography is necessary when communicating in any untrusted medium, which includes any network, particularly the Internet [1].Within the context of any application-to-application communication, there are some security requirements, including:
