The literature introduces one method that solves the problem of mobile-code security: Language-Based Security,and decribes in detail several methods in this research area, such as Proof-Carrying Code(PCC) and Typed Assembly Language(TAL). Our resolvation of mobile-code safety is presented at last.展开更多

The cryptosystem based on Goppa code has high security, but can be achieved poor. The cryptosystems based on other error correcting codes have higher performance than Goppa code. But there are still some disadvantages to solve. At last, the paper produce an assumption of the Niederreiter cascade combination cryptosystem based on double public-keys under complex circumstances, which has higher performance and security than the traditional cryptosystems.展开更多
