Original Scheme

Recently, Lee proposed two quantum signature schemes with message recovery. This paper shows insecurity in their schemes such that the scheme could be repudiated by the receiver Bob. Then, this paper proposes an arbitrated quantum signature scheme based on the correlation of Einstein–Podolsky–Rosen (EPR) pairs. Compared with Lee's scheme, the new scheme not only maintains the advantages of the original scheme but offers a higher efficiency in transmission and it can also avoid being disavowed by the receiver.

We show that quantum entanglement is helpful in improving the security of arbitrated quantum signature (AQS). Using the properties of quantum entanglement, a potential forgery which might occur in arbitrated quantum signature schemes without using them can be avoided. The fact is illustrated by relevant schemes.

Quantum Digital Signature

For the construction of post-quantum digital signature schemes that satisfy the strengthened criterion of resistance to quantum attacks, an algebraic carrier is proposed that allows one to define a hidden commutative group with two-dimensional cyclicity. Formulas are obtained that describe the set of elements that are permutable with a given fixed element. A post-quantum signature scheme based on the considered finite non-commutative associative algebra is described.
