Web20 de out. de 2024 · Boneh et al. introduced mediated RSA (mRSA) in 2001 in an attempt to achieve faster key revocation for medium-sized organizations via the involvement of a security mediator (SEM) as a semi-trusted third party to provide partial ciphertext decryption for the receiver. In this paper, a pairing-free security mediated encryption scheme … Web2 de dez. de 2024 · Different from RSA, ElGamal encryption is probabilistic, meaning that one plaintext can be encrypted to many possible different ciphertexts. The security of ElGamal encryption depends upon the difficulty of solving the discrete logarithm problem. The applications of ElGamal encryption are described as follows.
