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.

Encryption is the most powerful way to secure information by protecting it in the occurrence of theft, loss, or unauthorized access. It scrambles your data by requiring the receiver to have a secret key or password which would allow them to decrypt it. Web browsers indicate encrypted security techniques by showing a “lock” icon in the status bar. Webpages for online shopping will have either “http” at their beginning of the web address or a “lock” icon on the page. Email services should be protected by antivirus software. These
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.
In July 2015, many of the world’s high ranking cryptographers published that the loss and destruction induced by adopting a key escrow system 20 years ago would be even more serious, that would be very hard to identify security weaknesses that could be misused by
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.
There is constant concern about different kinds of devices and tools because of their vulnerability: laptops; personal computers in the home; libraries and public workstations; USB Flash Drives and email, to name a few. These items are easily accessible for those attempting to breach security.... ... middle of paper ... ...
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.
Cryptography plays a vital role in today’s computer and communications networks, protecting everything from business e-mails, bank transactions and Internet shopping. In recent years, hackers have demonstrated increased technical knowledge, in developing new alternatives to exploit network vulnerabilities, and create advanced software tools to automate attacks.
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.
The length of the key for the encryption can vary from being very short to extremely long, and the length of the message being encrypted. The protection of data being transferred between ATMs and the bank, and the use of cell phones, is the most common everyday encounter with encryption. To encrypt and decrypt information, a cipher is used. In a cipher, there is a set of well-defined steps that can be followed to encrypt and decrypt messages.
In the future, there will be a greater dependence on the Internet than ever before, and not just for e-commerce, but also for control of critical infrastructure (power generation, communications, transportation, etc.). While this will bring great efficiency, it also means that the downside of a severe attack on the Internet will be greater than ever.
In fact, according to several studies, more than half of all network attacks are committed internally. To determine the best ways to protect against attacks, we should understand the many types of attacks that can be instigated and the damage that these attacks can cause to data. The most common types of attacks include Denial of Service (DoS), password, and root access attacks.... ... middle of paper ... ...
In order to ensure the safety of Internet transactions, whether public or private, methodologies must be identified to safely and effectively encrypt information. Two methodologies are particularly associated with the issue of Internet security and deserve both an explanation and a contrast. These two methods are TCP/IP and cryptography. While the TCP/IP protocol was an initial first attempt at data security and integrity, it is insufficient. TCP/IP was not really designed as a security provision and is insufficient to meet the criteria which are necessary to ensure safe transactions (Computer Reseller News PG).
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:
Privacy exist wherever personal information or other sensitive information is collected, stored, used, and finally destroyed or deleted – in digital form or otherwise. The challenge of data privacy is to use data while safe-guarding individual's privacy preferences and their personally identifiable information. The fields of computer security, data security, and information security design and utilize software, hardware, and human resources to address this issue.
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.
