Revocable and Linkable Ring Signature real signer in linkable ring signature scheme under any circumstances. In other words, the revocability of RLRS is mandatory. The proposed RLRS scheme inherits the desired properties of group signature (anonymity revocation) and linkable ring signature (spontaneous group formation and linkability).

Attribute-Based Keyword Search from Latticesearch ability and can be further categorized into key-policy ABKS (KP-ABKS) and ciphertext-policy ABKS (CP-ABKS). In a KP-ABKS (resp., CP-ABKS) scheme, a trapdoor that is associated with an access policy . (resp., an attributes string .) can only be used to search over ciphertexts that is associated

Group Key Exchange from CSIDH and Its Application to Trusted Setup in Supersingular Isogeny Cryptosyst-quantum Diffie-Hellman type key exchange protocol from a commutative group action. The proposed group key exchange protocol called G-CSIDH uses the same size prime modulus . as that in CSIDH for the same security level, and the security of G-CSIDH is reduced to the security of CSIDH..In addition,
