A Threshold Authenticated Encryption Scheme Based on Elliptic Curve Cryptosystem
نویسنده
چکیده
A (t,n) threshold authenticated encryption scheme allows more than t signers to generate an authenticated cipher-text for a message and only the designated verifier can verify the message. Recently, Chung et al. [1] proposed a (t, n) threshold authenticated encryption scheme by applying a division-of-labor signature technique. However, we showed that the scheme has a design flaw. Then, we proposed a new authenticated encryption scheme based on elliptic curve cryptosystem. The new authenticated encryption scheme is more efficient.

Improvement on a Threshold Authenticated Encryption Scheme
The authenticated encryption scheme allows one signer to generate an authenticated cipher-text so that no one except the designated verifier can recover the message and verify the message. In a (t, n) threshold authenticated encryption scheme, any t or more signers can generate an authenticated encryption for a message and send it to the designated verifier. Compared with the conventional encry...
متن کاملDigital signature with message recovery and its variants based on elliptic curve discrete logarithm problem
In this article, we shall adopt the concepts of elliptic curve cryptosystems and self-certified public keys to build a novel digital signature scheme with message recovery. The public key and the identity of the user can be authenticated simultaneously in recovering the message. In addition, we shall also present three extended digital signature schemes based on the proposed scheme. The first i...
متن کاملA Secure and Efficient Convertible Authenticated Encryption Scheme with Message Linkages Using Elliptic Curve Cryptosystem
A convertible authenticated encryption scheme is very useful for transmitting a confidential message in insecure communication networks. This paper proposes a convertible authenticated encryption scheme with message linkages for message flows using Elliptic Curve Cryptography (ECC). The proposed scheme has the following advantages. (1) It can provide non-repudiation when the signer repudiates h...
متن کاملConstructing Secure Mobile-Agent-Based Consumer Electronic Applications
This paper proposes two appropriate security schemes for protecting consumer electronic applications in mobile agent based networks. As far as mobile agent security is concerned, we develop a proxy signature scheme for protecting mobile agents against malicious agent hosts using the ECC-based self-certified public key cryptosystem. The proposed proxy signature scheme can protect users’ private ...
متن کاملECC Based Convertible Authenticated Encryption Scheme Using Self-Certified Public Key Systems
This paper presents an ECC (Elliptic Curve Cryptography) based convertible authenticated encryption (CAE) scheme using self-certified public key systems. Combining the merits of self-certified public key cryptosystems, the proposed scheme has the property that authenticating the public key and verifying the signature can be simultaneously carried out within one step, which helps reducing comput...
