The Barth-Boneh-Waters Private Broadcast Encryption Scheme Revisited
Zhengjun Cao, Lihua Liu
The primitive of private broadcast encryption introduced by Barth, Boneh and Waters, is used to encrypt a message to several recipients while hiding the identities of the recipient…
Remarks on the Cryptographic Primitive of Attribute-based Encryption
Zhengjun Cao, Lihua Liu
Attribute-based encryption (ABE) which allows users to encrypt and decrypt messages based on user attributes is a type of one-to-many encryption. Unlike the conventional one-to-one…
A Note on the Bellare-Rivest Protocol for Translucent Cryptography
Zhengjun Cao, Lihua Liu
We remark that the Bellare-Rivest protocol for translucent cryptography [J. Cryptology (1999) 12: 117-139] can not truly enable the government to decrypt partial encrypted communic…
Remarks on Quantum Modular Exponentiation and Some Experimental Demonstrations of Shor's Algorithm
Zhengjun Cao, Zhenfu Cao, Lihua Liu
An efficient quantum modular exponentiation method is indispensible for Shor's factoring algorithm. But we find that all descriptions presented by Shor, Nielsen and Chuang, Markov…
Remarks on AKS Primality Testing Algorithm and A Flaw in the Definition of P
Zhengjun Cao, Lihua Liu
We remark that the AKS primality testing algorithm [Annals of Mathematics 160 (2), 2004] needs about 1,000,000,000 G (gigabyte) storage space for a number of 1024 bits. The require…
A Fast String Matching Algorithm Based on Lowlight Characters in the Pattern
Zhengjun Cao, Lihua Liu
We put forth a new string matching algorithm which matches the pattern from neither the left nor the right end, instead a special position. Comparing with the Knuth-Morris-Pratt al…
