The Transport Layer Security (TLS) protocol aims to provide confidentiality and integrity of data in transit across untrusted networks. TLS has become the de facto protocol standard for secured Internet and mobile applications. TLS supports several symmetric encryption options, including a scheme based on the RC4 stream cipher. In this paper, we present(More)
The Transport Layer Security (TLS) protocol aims to provide confidentiality and integrity of data in transit across untrusted networks. TLS has become the de facto secure protocol of choice for Internet and mobile applications. DTLS is a variant of TLS that is growing in importance. In this paper, we present distinguishing and plaintext recovery attacks(More)
The Datagram Transport Layer Security (DTLS) protocol provides confidentiality and integrity of data exchanged between a client and a server. We describe an efficient and full plaintext recovery attack against the OpenSSL implementation of DTLS, and a partial plaintext recovery attack against the GnuTLS implementation of DTLS. The attack against the OpenSSL(More)

Recently, a new scheme to protect clients against DNS cache poisoning attacks was introduced. The scheme is referred to as DepenDNS and is intended to protect clients against such attacks while being secure, practical, efficient and conveniently deployable. In our paper we examine the security and the operational aspects of DepenDNS. We highlight a number(More)
