Survival Guide Encryption, Authentication, Digests, MAC and Signatures. This is a survival guide covering the mind numbing topics of Cryptography, Encryption, Authorization and Authentication. For the mathematically challenged and who is not the maths involved in cryptography are gruesome in the extreme and are covered, if at all, at the level of stuff happens. The guide concentrates on system functionality and consists almost exclusively of descriptions and explanations rather than specific commands or implementations. We already have more awesome games than we can possibly play, so why not add a bunch more Heres all the big games coming out this summer.

Many of these terms are explained further in the text others are left dangling either to create a sense of tension in the reader or, more likely, because we have no idea what they mean. Authentication. The process or procedures used to verify that data or information asserting that it originates from a source can only have come from that source. Techniques used include digital signatures, MACs and even good ole passwords. What if you could throw a virtual party whenever you want that your friends from around the world could attend at a seconds notice Thats the idea behind.

This is a survival guide covering the mindnumbing topics of Cryptography, Encryption, Authorization and Authentication. In case you havent noticed, we here at Lifehacker have spent the day gleefully reveling in fullblown Eclipse Madness. But now that the blessed event is behind us. Once Authenticated you will, typically, still need to be Authorized to access specific resources or information. Authorization. When a user has Authenticated they are typically Authorized, based on their login credentials or account properties to access, or deny access to, certain systems resources such as files, applications or network resources. The term privilege is sometimes used synonymously for Authorization, thus a user may have enough privileges to access resource X but not resource Y. They are Authorized to access X but not Authorized to access Y. Bit Strength. Is defined in bits and is a measure of the amount of work needed to break a cryptographic algorthm. Bit Strength provides a method to measure the relative strength of one encryption alogithm against another. Depending on the algorithm the Key Size and Bit Strength may, or may not, be the same. NIST Publication SP 8. Part 1 Section 5. NISTs current recommendation 2. Cipher. A cipher a. To cipher a. k. a. Clear Text. A. k. Opera Mini Windows Ce 6 Download on this page. A block of data to which no encryption process has been applied or a block of data that results from a decryption or deciphering operation. Credentials. A fancy name for what most of us would call a password though it can take other forms such as a hardware token or biometric details. Your credentials are a way of proving that you are who you say you are. Since you should be the only person or group of persons in some cases who know or have access to your credentials, when you present them to a system or network it proves that you are who you say you are. After some form of exchange which will include presenting your credentials for instance, typing in a password you will be Authenticated. Once Authenticated you, typically, will still need to be Authorized to access specific resources or information. Decipher. Apply an decryption algorithm to an encrypted block of text and, given the appropriate keys, turn it into plain text. Most, but not all, ciphers use the same algorithm to encrypt and decrypt. Encryption. The process of transforming data using a cipher or encryption algorithm. Techniques used may be symmetric or asymmetric. Hasha. k. a. digest or one way hash or fingerprint. An algorithm for reducing an infinitely large block to a unique octect string of a fixed and significantly smaller size for example 1. Encad Driver For Windows 7'>Encad Driver For Windows 7. Hashes are used to ensure message integrity and are used in MACs or digital signatures. The term fingerprint is occasionally used in the sense that a fingerprint is a substitute for the whole person, so the hash becomes a fingerprint that may be stored or transmitted independently of a message or data but can always to used to verify the message or data integrity. Key Size. A. k. a. The number of bits used for the key of an encryption algorithm in general, the more bits the stronger the cipher. Many algorithms can take variable key sizes allowing them to be progressively strengthened over time. Key length key size may not the same, and should not be confused with, the Bit Strength of an algorithm. Thus, an RSA Key lengthKey size of 2. Bit Strength of 1. Plain Text. A. k. A block of data to which no encryption has been applied or a block of data that results from a decryption or deciphering operation. Cryptographic Overview. Cryptography according to Webster is the enciphering and deciphering of messages in secret code or cipher also the computerized encoding and decoding of information. It is the process of transforming enciphering or encrypting data called clear or plain text using some process a cipher or encryption algorithm into some gobbledygook that can only be transformed back deciphered or decrypted into plain text if the recipient has some some secret knowledge such as a key or a set of keys. Historically the ciphers, or encryption algorithms, used formed the secret. For example shift every character one position left the cipher that we used as kids when sending secret messages to our friends. The weakness here is that if the method or encryption algorithm the cipher is discovered all communication sent using that algorithm or cipher can be converted into plain text deciphered. A new algorithm has to be created and propagated to all parties before we can start sending messages again. Modern cryptography assumes that the bad guys will discover the cryptographic algorithm, indeed, for reasons we will see later, the algorithms themselves are widely published. Instead, the secret lies with a unique key or keys which are used by the algorithm to transform encipher or decipher the data. If the key is exposed or compromised a. The bad guy has to start all over again to discover the key with no greater knowledge than before but with, hopefully, tightened end user key security procedures in place. Cryptographic algorithms are not provably secure. Instead, they are widely published and exposed to repeated attack by dedicated researchers and specialists black hat testers who love this kind of stuff. Only having resisted repeated and sustained attacks are the algorithms used operationally. Since research into the cryptographic algorithms is ongoing it can occasionally mean that apparently robust, mature algorithms need to be replaced when weaknesses are discovered. A recent example here relates to theoretical weaknesses being discovered in the MD5 digest algorithm around 2. While it is always possible to use a brute force attack to find a key, cryptographic systems use a concept known as computationally infeasible which simply means that it would cost too much or take too long to mount such a brute force attack. Computationally infeasible is based on todays technology and is therefore a relative not absolute definition and does change over time. Thus, for example, in some algorithms the key size is typically increased over time as raw computational capacity increases. If a secret key, or keys, are obtained by an attacker by stealth, brute force, luck or other nefarious means then the last thing they are likely to do is to boast about it, which will only trigger the user to replace the keys. Instead, the bad guys will simply and quietly continue to eavesdrop on supposedly secure communications. This is a serious problem and is typically handled by some combination of maintaining the keys in a tamper proof which will destroy the key if a compromise is attempted or a tamper aware environment a.
