#### What is a knapsack cryptosystem?

This looks like a knapsack cryptosystem, which are usually solved by lattice reduction algorithms modelling a Shortest Vector Problem (SVP). We noticed that the title of the challenge “Namura” hints at the paper describing this algorithm, Naskao and Murakami’s Knapsack Public-Key Cryptosystem Using Chinese Remainder Theorem.

#### What is the difference between RSA and private key crypto?

RSA is the most widely used public key crypto system. In private key crypto, both parties share the same private key, and this is used for both encryption and decryption, such as the block ciphers we were working with before.

#### What is the code resource for modular arithmetic?

Code Resource The answer is crypto{10245, -8404} Modular Arithmetic 1 This problem is different from normal modular process because it involves modular congruence. If you haven’t noticed, the two equations given contain ≡ instead of the normal =. ≡ denotes modular congruence and one of its propertiesis if a≡ b mod n, then b ≡ a mod n.
