An ID-Based Linearly Homomorphic Signature Scheme and Its Application in Blockchain by Qun Lin; Hongyang Yan; Zhengan Huang; Wenbin Chen; Jian Shen; Yi Tang is a Engineering article available to read on EtoBox.
Identity-based cryptosystems mean that public keys can be directly derived from user identifiers, such as telephone numbers, email addresses, and social insurance number etc.. So they can simplify key management procedures of certificatebased public key infrastructures and can be used to realize authentication in blockchain. Linearly homomorphic signature schemes allow to perform linear computations on authenticated data. And the correctness of the computation can be publicly verified. Although a series of homomorphic signature schemes have been designed recently, there are few homomorphic signature schemes designed in identity-based cryptography. In this paper, we construct a new ID-based linear homomorphic signature scheme, which avoids the shortcomings of the use of publickey certificates. The scheme is proved secure against existential forgery on adaptively chosen message and ID attack under the random oracle model. ID-based linearly homomorphic signature schemes can be applied in e-business and cloud computing. Finally, we show how to apply it to realize authentication in blockchain.
