no footnotes date November 2010 In cryptography , a salt consists of Random Number Generator random bit s, creating one of the inputs to a one way function . The other input is usually a password or passphrase . The output of the one way function can be stored rather than the password, and still be used for authenticating users. The one way function typically uses a cryptographic hash function . A salt can also be combined with a password by a key derivation function such as PBKDF2 to generate a key cryptography key for use with a cipher or other cryptography cryptographic algorithm . In a typical usage for password authentication, the salt is stored along with the output of the one way function, sometimes along with the number of iteration s to be used in generating the output for key stretching . Early Unix systems used a 12 bit salt, but modern implementations use larger lengths from 48 to 128 bits. Salt is closely related to the concept of Cryptographic nonce nonce . The benefit provided by using a salted password is making a lookup table assisted dictionary attack against the stored values impractical, provided the salt is large enough. That is, an attacker would not be able to create a precomputed lookup table i.e. a rainbow table of hashed values password salt , because it would take too much space. A simple dictionary attack is still very possible, although much slower since it cannot be precomputed. Unix implementations Earlier versions of Unix used a Passwd file password file code etc passwd code to store the hashes of salted passwords passwords prepended with two character random salts . Note that in these older versions of Unix, the salt was also stored in the passwd ... files. See also Password cracking Cryptographic nonce Initialization vector Padding cryptography , sometimes ...

The initiative involved four standard algorithms a data encrypt encryption algorithm called Skipjack cipher Skipjack , along with the Clipper chip that included the Skipjack algorithm, a digital signature algorithm, Digital Signature Algorithm DSA , a hash function, SHA 1 , and a key exchange protocol. ref Note2 Captstone s first implementation was in the Fortezza PCMCIA card . The initiative encountered massive resistance from the cryptographic community, and eventually the US government abandoned the effort. The main reasons for this resistance were concerns about Skipjack cipher Skipjack s design, which was Classified information classified , and the use of key escrow in the Clipper chip.

Visual cryptography is a cryptography cryptographic technique which allows visual information pictures, text, etc. to be encrypted in such a way that decryption becomes a mechanical operation that does not require a computer. Visual cryptography was pioneered by Moni Naor and Adi Shamir in 1994. They demonstrated a visual secret sharing scheme, where an image was broken up into n shares so that only someone with all n shares could decrypt the image, while any n 1 shares revealed no information about the original image. Each share was printed on a separate transparency, and decryption was performed by overlaying the shares. When all n shares were overlaid, the original image would appear. Using a similar idea, transparencies can be used to implement a one time pad encryption, where one transparency is a shared random pad, and another transparency acts as the ciphertext.

Certificateless cryptography is a variant of ID based cryptography intended to prevent the key escrow problem. Ordinarily, keys are generated by a certificate authority or a key generation center KGC who is given complete power and is implicitly trusted. To prevent a complete breakdown of the system in the case of a compromised KGC, the key generation process is split between the KGC and the user. The KGC first generates a key pair, where the private key is now the partial private key of the system. The remainder of the key is a random value generated by the user, and is never revealed to anyone, not even the KGC. All cryptographic operations by the user are performed by using a complete private key which involves both the KGC s partial key, and the user s random secret value. One disadvantage of this is that the identity information no longer forms the entire public key. To encrypt a message to another user, three pieces of information are needed 1 the other user s public key and 2 identity, and also 3 the third party s public information. To decrypt, a user just needs to use their private key. For tight security, a certificateless system has to prove its security against two types of adversaries. Type 1 Adversary Refers to any third party who can fake the user s public keys, corresponding to the user s random secret value. Type 2 Adversary Refers to a compromised or malicious KGC, who has access to the partial public and private keys of all users. References Sattam S. Al Riyami and Kenneth G.

Unreferenced date June 2009 In cryptography , a boolean function is said to be complete if the value of each output bit depends on all input bits. This is a desirable property to have in an encryption cipher, so that if one bit of the input plaintext is changed, every bit of the output ciphertext has an average of 50 probability of changing. The easiest way to show why this is good is the following consider that if we changed our 8 byte plaintext s last byte, it would only have any effect on the 8th byte of the ciphertext. This would mean that if the attacker guessed 256 different plaintext ciphertext pairs, he would always know the last byte of every 8byte sequence we send effectively 12.5 of all our data . Finding out 256 plaintext ciphertext pairs is not hard at all in the internet world, given that standard protocols are used, and standard protocols have standard headers and commands e.g. get , put , mail from , etc. which the attacker can safely guess. On the other hand, if our cipher has this property and is generally secure in other ways, too , the attacker would need to collect 2 sup 64 sup 10 sup 20 sup plaintext ciphertext pairs to crack the cipher in this way.
