A new cryptographic data protection mechanism has been jointly proposed by experts from the HSE Tikhonov Moscow Institute of Electronics and Mathematics, Sber, and QApp. The researchers have developed a postquantum ring signature scheme that ensures anonymity (within a defined group of participants), as well as the integrity and authentication of the source of digital transactions, even in the presence of an adversary equipped with a quantum computer.
