摘要： An improved blind signature system not requiring computation during blinding for anticipating which of a plurality of possible signatures will be made during signing, while still allowing the blinding party to unblind and recover the unanticipated kind of signature on what was blinded. An exemplary embodiment blinds by forming a product including a plurality of generators raised to powers normally secret from the signing party, and unblinds by forming a product with the multiplicative inverse of a signed form of the generators raised to the original powers. Re-blinding allows a signature on a value to be transformed into a signature on a particular blinded form of the value.

摘要： Disclosed is a system for mobile data isolation, comprising of a tag control management module and a mobile data management module. The tag control management module comprises a tag generator, a tag storage management module and a tag transmission control module. The mobile data management module primarily identifies user authority and data confidentiality level according to tags, operates and controls the mobile application of mobile data, to realize fine-grained confidentiality security protections of the mobile data. The mobile data management module is divided into security isolation control of a data processing process, security control of a data transmission process and security isolation control in data storage. Meanwhile, a method for mobile data isolation is also disclosed. Isolation and fine-grained operation and control of data on a mobile intelligent terminal can be performed effectively, realizing different confidentiality policies and ensuring the confidentiality security of mobile data.
