Securely outsourcing cookies to the cloud via private information retrieval

摘要: Many smartphone applications are web based and rely on cookies to maintain the status of a session. Cookies, however, may lead security threats since they contain sensitive information. In addition, an attacker having access cookie can easily impersonate legitimate user. this paper, we propose implement system that securely outsources browser cloud ensures user privacy using Private Information Retrieval. Experimental evaluation traces collected from operational cellular WiFi networks demonstrates our achieves satisfactory performance for most real-life browsing scenarios: average latency is within 1.0 1.2 seconds (well users' tolerance) even when retrieving tens over LTE or network, amount generated traffic significantly lower than downloading entire database.
