This paper presents a short signature scheme whose security is based upon two computationally hard problems, namely, Discrete Logarithm Problem (DLP) and Integer Factorization Problem (IFP). In this scheme, biometric feature values of the signer are used to compute biometric cryptographic key, which is further used in signature generation. As biometric data is unique to a person, the signature cannot be forged. Also the length of the signature is short, which helps to reduce communication overhead. The verification cost of the proposed scheme is low, thus applicable in real life scenarios, such as e-voting, e-cash and e-commerce.
