    The Java Cryptography Architecture JCA is a framework for working with cryptography using the Java programming language Java programming language . It forms part of the Java Computer security security API, and was first introduced in JDK 1.1 in the Javadoc SE package java.security java security package. The JCA uses a Provider model provider based architecture and contains a set of APIs for various purposes, such as encryption , Key management key generation and management , Cryptographically secure pseudorandom number generator secure random number generation , Public key certificate certificate validation , etc. These APIs provide easy way for developers to integrate security into application code.

  1. Visual cryptography

    Visual cryptography is a cryptography cryptographic technique which allows visual information pictures, text, etc. to be encrypted in such a way that the decryption can be performed by the human visual system, without the aid of computers. 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. Example Image Visual crypto animation demo.gif frame right A demonstration of visual cryptography In this example, the Wikipedia logo has been split into two shares. Each white pixel in the original logo is split into two of the same small blocks that have full black and white pixels. When these two blocks are overlaid, they align exactly, and so the result is a light colored block with half black and half white pixels . Each black pixel in the original logo is split into two complementary small blocks. When these two blocks are overlaid, the result is a completely black block. If each pixel in the original image is split randomly into two shares as described above, the shares are correlated together ...

Capstone was driven by the National Institute for Standards and Technology NIST and the National Security Agency NSA the project began in 1993 ref Note1 . 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, 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.

  1. Completeness (cryptography)

    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.

  1. Certificateless cryptography

    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 it s 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.
