This is standard mathematical notation and not specific to cryptography. The $\Pi$ symbol means Product in much the same sense $\Sigma$ means Sum. For instance, $$\prod_{i=0}^2{u_i^{m_i}} = u_0^{m_0}u_1^{m_1}u_2^{m_2}$$

Here is how you do a literature search, to find relevant research papers in the literature: You identify some search terms related to your topic, and search for them on Google Scholar and other places (e.g., Crypto.SE, via web search, on Citeseer). (For cryptographic work, also try searching Google with site:eprint.iacr.org and your search terms, to turn ...

In my practice (Smart Cards, often using DES and increasingly AES) Key Expansion is often used to designate production of subkeys in a block cipher. This process is often a mere bit extraction, as part of the algorithm's Key Schedule. Key Diversification is, almost exclusively, the process of producing a device key from its serial number (or other ...

It depends on whether you're in university or not. If you are and your school has the for-pay journals, start by searching them for the topic. Also try 'eprint.iacr.org' and google scholar. To find the most important or seminal papers in a topic you should look at the number of people that have cited it. This is an imperfect but useful heuristic for ...

Per my comment, I'd like to suggest a definition for "non-iterative hash function", and propose some constructions that fit the definition. I will also suggest an alternate name (though it may not help much with searching for papers on the topic). Let $\mathcal{M}$ be the message space of a hash function, e.g. $\mathcal{M}=\{0,1\}^{*<\ell}$, the set of ...

I'm just reading the book Advances in Elliptic Curve Cryptography, and Chapter II (by Dan Brown) is about provable security of ECDSA. It lists some necessary conditions for the ECDSA components (group, conversion function, RNG, hash function), each with an associated forgery. For example, the group has to be resistant against discrete logarithms, as well as ...

It's the notation for the Encryption scheme in use, consisting key generation, decryption and encryption algorithms. Open form: Π = (Gen,Enc,Dec)
