In computer based system, key for the problem of identification, authentication and secrecy can be found in the field of cryptography. Dependence on public key infrastructure and to receive certificates signed by Certificate Authority (CA) to authenticate oneself for exchange of encrypted messages is one of the most significant limitation for the widespread adoption of Public Key Cryptography (PKC) as this process is time engrossing and error prone. Identity based cryptography (IBC) aspires to reduce the certificate and key management overhead of PKC. IBC’s important primordial is Identity-based Encryption (IBE). IBE provided emergent for perception of Identity based signature (IBS) schemes. In this paper, overview of IBE and IBS schemes has been given. Also, a survey on various IBE and IBS schemes has been performed to review different problems related to them. Finally, feasibility and applicability of IBC in current and future environments has been discussed.

Identity Based Cryptography

A revolutionary change to public-key cryptography can be considered as an Identity Based Cryptography (IBC) in which identity of the receiver is being used as a public key for encrypting a message and Key Generation Centre (KGC). IBC will generate and distribute the private key to each user to decrypt a message. The thought behind presenting the scheme was to improve and reduce the complexity of certificate and key management, but it also gives rise to key escrow problem, access to encrypted information to unauthorized users. The paper represents Improved Identity-Based Encryption Scheme (IIBES) for Domain Name System (DNS) security which provides confidentiality and authentication through modified identity based encryption and identity based digital signatures. The IIBES comprises key revocation mechanism for non-revoked users and also eliminates key escrow problem. Thus, the IIBES aids to implement the identity-based cryptography more safely in reality and protects DNS against cache poisoning, spoofing attack and masquerade attack. Doi: 10.28991/esj-2021-01259 Full Text: PDF

Certificateless Signature

Certificateless public key cryptography eliminates inherent key escrow problem in identity-based cryptography, and does not yet requires certificates as in the traditional public key infrastructure. Recently, Yu et al. propose a new certificateless signature scheme and their scheme offers shorter system parameters and higher computational efficiency than the previous schemes in the standard model. However, in this paper, we show Yu et al.'s certificateless signature scheme is vulnerable to malicious-but-passive KGC attack where a malicious KGC can forge valid signatures by embedding extra trapdoors in the system parameter.

Certificateless Signature

Based an identity-based signature scheme, we givea certificateless signature scheme. And then we propose a certificateless blind signature (CLBS) scheme in this paper. This schemeis more efficient than those of previous schemes by pre-computing the pairing e (P, P)=g. Based on CL-PKC, it eliminates theusing of certificates in the signature scheme with respect to thetraditional public key cryptography (PKC) and solves key escrowproblems in ID-based signature schemes. Meanwhile it retains themerits of BS schemes. The proposed CLBS scheme is existentialunforgeable in the random oracle model under the intractabilityof the q-Strong Diffie-Hellman problem.

Multivariate Public Key Cryptography (MPKC) is one of the main candidates for post-quantum cryptography, especially in the area of signature schemes. In this paper, we instantiate a certificate Identity-Based Signature (IBS) scheme based on Rainbow, one of the most efficient and secure multivariate signature schemes. In addition, we revise the previous identity-based signature scheme IBUOV based on the Unbalanced Oil and Vinegar (UOV) scheme on the security and choice of parameters and obtain that our scheme is more efficient than IBUOV in terms of key sizes and signature sizes.

The concept of Identity Based Cryptography introduced the idea of using arbitrary strings such as e-mail addresses and IP Addresses to form public keys with the corresponding private keys being created by the Trusted Authority(TA) who is in possession of a system-wide master secret. Then a party, Alice who wants to send encrypted communication to Bob need only Bob's identifier and the system-wide public parameters. Thus the receiver is able to choose and manipulate the public key of the intended recipient which has a number of advantages. While IBC removes the problem of trust in the public key, it introduces trust in the TA. As the TA uses the system-wide master secret to compute private keys for users in the system, it can effectively recompute a private key for any arbitrary string without having to archive private keys. This greatly simplifies key management as the TA simply needs to protect its master secret.
