And Performance

Smart grid has emerged as the next-generation electricity grid with power flow optimization and high power quality. Smart grid technologies have attracted the attention of industry and academia in the last few years. However, the tradeoff between security and efficiency remains a challenge in the practical deployment of the smart grid. Most recently, Li et al. proposed a lightweight message authentication scheme with user anonymity and claimed that their scheme is provably secure. But we found that their scheme fails to achieve mutual authentication and mitigate some typical attacks (e.g., impersonation attack, denial of service attack) in the smart grid environment. To address these drawbacks, we present a new message authentication scheme with reasonable efficiency. Security and performance analysis results show that the proposed scheme can satisfy the security and lightweight requirements of practical implementations and deployments of the smart grid.

This paper presents the vulnerabilities analyses of KL scheme which is an ID-based authentication scheme for AMI network attached SCADA in smart grid and proposes a security-enhanced authentication scheme which satisfies forward secrecy as well as security requirements introduced in KL scheme and also other existing schemes. The proposed scheme uses MDMS which is the supervising system located in an electrical company as a time-synchronizing server in order to synchronize smart devices at home and conducts authentication between smart meter and smart devices using a new secret value generated by an OTP generator every session. The proposed scheme has forward secrecy, so it increases overall security, but its communication and computation overhead reduce its performance slightly, comparing the existing schemes. Nonetheless, hardware specification and communication bandwidth of smart devices will have better conditions continuously, so the proposed scheme would be a good choice for secure AMI environment.

H.264/AVC is a widespread standard for high definition video (HD) for example DVD and HD videos on the internet. To prevent unauthorized modifications, video authentication can be used. In this paper, we present a cryptanalysis of a H.264/AVC video authentication scheme proposed by Saadi et al. [1] at EUSIPCO 2009. Our result will prevent situations where newer schemes are developed from the scheme thus amplifying the flaw. The designers claimed that the scheme can detect modifications on watermarked video. However, we show that an attacker can modify the watermarked video and compute a valid watermark such that the recipient will retrieve a watermark from the modified watermarked video that will match what the recipient computes during video authentication check. Thus, the recipient will think the tampered video is authentic. The first main problem of the scheme is its use of hash functions for watermark generation. Since hash functions are public functions not depending on any secret, the attacker can modify the watermarked video and feed this through the hash function to compute a new watermark. The second problem is that it is possible for the attacker to perform watermark embedding thus producing a modified watermarked video. On receiving the modified video, the recipient recomputes the watermark and compares this with the watermark extracted from the video. They will match because the embedded watermark and recomputed watermark use the same hash function based watermark generation and the same input i.e. the modified video. Our cryptanalysis strategy applies to any watermarking based video authentication scheme where the watermark and embedding are not functions of secrets. As countermeasure, the functions should be designed so that only legitimate parties can perform them. We present two improved schemes that solve this problem based on private key signing functions and message authentication functions respectively.
