WebAbstract. The RSA (Rivest, Shamir, Adleman) cipher algorithm has captured the imagination of many mathematicians by its elegance and basic simplicity ever since it was introduced in 1978. Numerous descriptions of the algorithm have been published. WebJul 28, 2024 · In 1976 W. Diffie and M. Hellman proposed the concept of public-key cryptography concept [ 1 ]. To construct this public-key cryptosystem one needs to construct a one-way trap-door function. To achieve this, a hard computational problem should be selected, which nevertheless has simple solutions in some special cases. tp link hrvatska
