ID-based cryptography. Iden.y-based cryptography is a type of public-key cryptography in which a publicly known string representing an individual or organization is used as a public key. The public string could include an email address, domain name, or a physical IP address.. - Abstract. In this paper we introduce a novel type of cryptographic scheme, which enables any pair of users to communicate securely and to verify each other 's signatures without exchanging private or public keys, without keeping key directories, and without using the services of a third party. The scheme .Definition. Iden.y-based cryptography refers to a set of public key cryptographic primitives where public keys consist of users ' iden.y information and nothing else. Its advantage is to alleviate the need for digital certificates linking public keys to the iden.y of the corresponding user..IDEN.Y-BASED CRYPTOSYSTEMS AND SIGNATURE SCHEMES. Adi Shamir. Department of Applied Mathematics. The Weizmann Ins.ute of Science. Rehovot, 76100 Israel. THE IDEA. In this paper we introduce a novel type of cryptographic scheme, which enables any pair of users to communicate securely and to .

In this paper, we develop an efficient ECC-based self-certified public key cryptosystem ECCSCPKC quite suitable for efficiently securing electronic transactions..An encryption method is presented with the novel property that publicly revealing an encryption key does not thereby reveal the corresponding decryption key..SSH keys authenticate users and hosts in SSH. They are used for single sign-on and machine-to-machine access. Security and convenience!.A new iden.y-based short signature IBS is proposed in this paper. The new scheme is constructed in the standard model and has short public parameters and private keys..
