Software verification has been well applied in safety critical areas and has shown the ability to provide better quality assurance for modern software. However, as lines of code and complexity of software systems increase, the scalability of verification becomes a challenge. In this paper, we present an automatic software verification framework TSV to address the scalability issues: (i) the extended structural abstraction and property-guided program slicing to solve large-scale program verification problem, saving time and memory without losing accuracy; (ii) automatically select different verification methods according to the program and property context to improve the verification efficiency. For evaluation, we compare TSV's different configurations with existing C program verifiers based on open benchmarks. We found that TSV with auto-selection performs better than with bounded model checking only or with extended structural abstraction only. Compared to existing tools such as CMBC and CPAChecker, it acquires 10%-20% improvement of accuracy and 50%-90% improvement of memory consumption.

Internet has been being becoming the most famous and biggest communication networks as social, industrial, and public infrastructure since Internet was invented at late 1960s. In a historical retrospect of Internet's evolution, the Internet architecture continues evolution repeatedly by going through various technical challenges, for instance, in early 1990s, Internet had encountered danger of scalability, after a short while it had been overcome and successfully evolved by applying emerging techniques such as CIDR, NAT, and IPv6. Especially this paper emphasizes scalability issues as technical challenges with forecasting that Internet of things era has come. Firstly, we describe the Identifier and locator separation scheme that can achieve dramatically architectural evolution in historical perspective. Additionally, it reviews various kinds of Identifier and locator separation scheme because recently the scheme can be the major design pillar towards future of Internet architecture such as both various clean-slated future Internet architectures and evolving Internet architectures. Lastly we show a result of analysis by analysis table for future of internet of everything where number of Internet connected devices will growth to more than 20 billion by 2020.

In this paper, we propose a scheme to employ an asymmetric fingerprinting protocol within a client-side embedding distribution framework. The scheme is based on a novel client-side embedding technique that is able to transmit a binary fingerprint. This enables secure distribution of personalized decryption keys containing the Buyer's fingerprint by means of existing asymmetric protocols, without using a trusted third party. Simulation results show that the fingerprint can be reliably recovered by using non-blind decoding, and it is robust with respect to common attacks. The proposed scheme can be a valid solution to both customer's rights and scalability issues in multimedia content distribution.
