A note on Tensor Simple Matrix Encryption Scheme
The simple matrix encryption scheme (Tao-Diene-Tang-Ding, PQCrypto 2013) has a problem of decryption failures. Quite recently, Petzoldt-Ding-Wang (http://eprint.iacr. org/2016/010...

Proofs of Space-Time and Rational Proofs of Storage
Abstract. We introduce a new cryptographic primitive: Proofs of SpaceTime (PoSTs) and construct a practical protocol for implementing these proofs. A PoST allows a prover to convin...

Commutativity, Associativity, and Public Key Cryptography
In this paper, we will study some possible generalizations of the famous Diffie-Hellman algorithm. As we will see, at the end, most of these generalizations will not be secure or w...

How to Generalize RSA Cryptanalyses
Recently, the security of RSA variants with moduli N = pr q, e.g., the Takagi RSA and the prime power RSA, have been actively studied in several papers. Due to the unusual composit...
