Hash Functions from Sigma Protocols and Improvements to VSH
Hash Functions from Sigma Protocols and Improvements to VSH Mihir Bellare and Todor Ristov Department of Computer Science and Engineering, University of California San Diego, 9500 Gilman Drive, La Jolla, CA 92093-0404, USA. URL: www-cse.ucsd.edu/users/mihir, www-cse.ucsd.edu/users/tristov Abstract. We present a general way to get a provably collision-resistant hash function from any (suitable) Σ-protocol. This enables us to both get new designs and to unify and improve previous work. In the first category, we obtain, via a modified version of the Fiat-Shamir proto- col, the fastest known hash function that is provably collision-resistant based on the standard factoring assumption. In the second category, we provide a modified version VSH* of VSH which is faster when hash- ing short messages. (Most Internet packets are short.) We also show that Σ-hash functions are chameleon, thereby obtaining several new and efficient chameleon hash functions with applications to on-line/off-line signing, chameleon signatures and designated-verifier signatures. 1 Introduction The failure of popular hash functions MD5 and SHA-1 [42, 43] lends an impetus to the search for new ones. The contention of our paper is that there will be a \niche" market for proven-secure even if not-so-fast hash functions. Towards this we provide a general paradigm that yields hash functions provably secure under number-theoretic assumptions, and also unifies, clarifies and improves previous constructs. Our hash functions have extra features such as being chameleon [25]. Let us now look at all this in more detail. -

Bestcrypt Base User Manual
BestCrypt Base User Manual Introduction • Introduction • BestCrypt Base Overview • HIPAA Compliance • Main Features 2 Introduction BestCrypt Base is an encryption software developed for small offices with local networks. Most offices do not usually have specially educated administrators to configure network, nor employees have experience of working with security software. BestCrypt Base has been designed to make the encryption process easy for everyone. Getting computers encrypted in a small business local network often becomes a challenge. On the one hand it is good if the encryption software has features of enterprise products such as central storage of recovery data and transparent encryption on users' computers. On the other hand, it would be better if central administration of encryption software for small offices were as simplified as possible. Ideally, a server should not be an expensive upmarket hardware, deployment should be simple, admin's console should be easy to use and require minimum attention. BestCrypt Base software combines features of encryption solutions for enterprise networks with interface simplicity of home software. There is a Key Server in the local network that helps in case of emergency and provides many of the functions proper to enterprise software. The Key Server may be a regular Windows computer or a cheap old computer without hard drive or/ and an operating system. How is it possible? Take a look at BestCrypt Base. It is a user-friendly software made to gurantee the security of your small business. See also: BestCrypt Base overview Main features 3 BestCrypt Base Overview The Introduction article states that BestCrypt Base is designed for small networks with computer users who are not specially trained as Network Administrators. -
Bestcrypt Container Encryption User Manual
BestCrypt Container Encryption User Manual Introduction • Why do you need BestCrypt? • Benefits of BestCrypt • BestCrypt Requirements • BestCrypt Specifications and Limitations 2 Why do you need BestCrypt? BestCrypt is oriented to a wide range of users. Whether you are in business and work with an accounts database, or you are a developer who is designing a new product, or you keep your private correspondence on your computer, you will appreciate a security system that restricts access to your data. With the advent of mass storage systems, a tremendous amount of information can be carried conveniently on even a small notebook computer. What happens to all this information if the computer is stolen at an airport? Suppose someone gains access to your computer without your knowledge. Do you know if your data has been copied and given to someone else? The main advantage of BestCrypt is that it is the most powerful, proven protection tool, based on cutting-edge technology, and available now for public use. Its mathematical basis was developed by outstanding scientists to keep all kinds of classified governmental documents and letters in deep secrecy. BestCrypt has a strong, built-in encryption scheme and contains no "backdoor". A "backdoor" is a feature that allows authorities with legal permission to bypass protection and to access data without the permission of the owner. Many commercial and government-certified systems contain backdoors, but not BestCrypt. The only way to access the data secured by BestCrypt is to have the correct password. 3 Benefits of BestCrypt Strong Security Once written to a BestCrypt file (container), data is never stored in an ‘open’ condition.
