P2P directory search: Signature Array Hash Table

Abstract: Bloom filters are a well known data structure for approximate set membership. Bloom filters are space efficient but require many independent hashes and consecutive memory accesses for an element test. In this paper, we develop a hash table data structure that stores string signatures in an array. This new signature array hash table (SAHT) supports faster element testing than a bloom filter and requires less memory than a standard hash table that uses linked-list chains. The SAHT also supports removal of elements (which a Bloom filter does not) and addition of elements at the expense of requiring about 1.5x more memory than a bloom filter with same false positive rate.

Minimum Space and Huge Security in 3D Password Scheme

Abstract: D password is a multifactor authentication scheme. For the authentication, it is require to presents a 3-D virtual environment where the user navigates and interacts with various objects. The sequence of actions and interactions toward the objects inside the 3-D environment constructs the user's 3-D password. The 3-D password can combine most existing authentication schemes such as textual passwords, graphical passwords, and various types of biometrics into a 3- D virtual environment. The design of the 3-D virtual environment and the type of objects selected determine the 3- D password key space. As per the reference(1) the author tells that the resulting 3D password space is very huge. In this paper we shows that the space is reduced and increase the security.

Password Authentication for multicast host using zero knowledge Proof

Abstract: The password which is a more secure and valuable data should be highly protected from eavesdropper. This paper presents how password required for authentication of members of group communication is securely delivered by the source or initiator of the group. The password delivery uses zero knowledge proof and sent to the group member in an encrypted format using cipher block mode encryption. The password delivered is a One Time Password which can be used for certain amount of time in order to ensure a highly secure communication environment among the group.

Mechanism for color management cache reinitialization optimization

Abstract: A printing system is disclosed. The printing system includes a color management unit having a hash table to store input colors and corresponding output colors and a lookup table (LUT). The printing system also includes one or more processors to reinitialize the hash table based on a hash table time and a interpolation time derived from concurrent real time measurements.

Password authentication based on public-key distribution cryptosystem

Abstract: A password authentication mechanism based on the public-key distribution cryptosystem is proposed. The scheme uses an authentication table to replace the traditional password file. With this scheme, even if the authentication table is comprised, the system security is preserved. The user's password is effectively bound to the user's identification in a timely, efficient, and simple manner. >
