A New Mobile Widget Algorithm Used to Resist Tamper Based on Code Signature
L. Tong, Jiaming He, Chen, Ken · ASME Press eBooks · 2011
In order to increase the system's ability against viruses to prevent the widget application from being tampered, enhance system security, the article proposes a tamper-resistant algorithm for mobile widget based on code signing. The algorithm uses public key infrastructure, achieving digital signature by private key encrypt message digest, verifying the signature's effectiveness through the public key, the signed data is in the performance of XML format, detecting the illegal file without digital signature or validation failure usually, identifying the malicious code and illegal procedure, thereby realize widget application's signature and verification under widget system.
