WebJan 1, 2024 · Pohlig–Hellman cipher is defined b y the computational difficulty of the DLP modulo p. In the present paper we use the notion of the commutativ ity of the encryption … WebThe appropriate commutative encryption function is provided by the exponen-tiation-encryption method proposed by Pohlig and Hellman in [7]. The last method is described as follows. Suppose pis a 2464-bit prime such that number (p 1) contains a large prime divisor q;for example, p= 2q+1.
