一个新的理想格上基于属性的加密方案
New attribute-based encryption on ideal lattices
摘要
Abstract
With the continuous development of cryptological technique, attribute-based encryption has received wide atten-tion in recent years as a new concept of cryptographic algorithm. But now most of attribute-based encryption schemes are based on the traditional public key cryptography of math problems, such as the large integer factorization and discrete log-arithm problems, which has the low operation efficiency and can’t resist the index attack and the quantum attack, limiting its development in the encryption system. This paper presents a new attribute-based encryption over ideal lattice. Com-pared with the existing attribute-based encryption schemes, the new scheme uses the special structure of ideal lattice, easy to implement and with a short public key and the ciphertext, its encryption and decryption algorithms are realized through a function, reducing the computational complexity greatly.关键词
