Detection of HTTPS malware traffic without decryption
Each year the world's dependency on the internet grows, especially its functionality relating to critical infrastructure and social connections. More than 80% of internet traffic is encrypted using Transport Layer Security (TLS) protocol, and it is predicted that this number will increase [8]. …

Non-linear operations and verifiable decryption in BGV
… too. Finally, an introduction to the verifiable decryption problem is introduced. Due to the very nature of FHE, the scientist only gets the encrypted results, and therefore has to ask the data owner to decrypt it. Verifiable decryption protocols are born precisely to ensure that this data …

Hiding Decryption Latency in Intel SGX using Metadata Prediction
… security add a significant performance overhead. Decryption of data using secret OTPs, which are generated by modified Counter Mode Encryption AES blocks, results in a significant latency overhead that contributes to the overall SGX performance loss. This thesis introduces a metadata prediction …

Compelled Decryption and the Right Against Self-Incrimination: Obsta Principiis
<p>Amidst the debate over compelled decryption, most courts and commentators have failed to recognize that the Act of Production Doctrine has swallowed the right against self-incrimination. The right against self-incrimination was created for the express purpose of preventing the government from …

Sniffing, Decoding and Decryption of GSM Signals Using low cost hardware and Open-source software
<p>We have participated in the creation of almost two terabytes of tables aimed at cracking A5/1, the most common ciphering algorithm used in GSM. Given 114-bit of known plaintext, we are able to recover the session key with a hit rate of 19%. The tables are expected to be unique as they provide …

The Elgamal Cryptosystem is better than Th RSA Cryptosystem for Mental Poker
… implementation is based on a joint encryption/decryption of individual cards. Both implementations use shared private key encryption/decryption schemes and neither uses a trusted third party (TTP). The comparison criteria will be concentrated on the security and computational complexity of the …

Evaluation of somewhat homomorphic encryption schemes
… of homomorphic operations before encountering a decryption failure, are much more efficient than their fully homomorphic counterparts. In this thesis, I present the empirical evaluation of two SWHE scheme prototypes built for IARPA's Security and Privacy Assurance Research (SPAR) program. The …

Cooperative Jamming in Wireless Networks - Turning Attacks into Privacy Protection
… completely take the place of various encryption/decryption schemes which are working based on successfully received packets. Adding CJWN to the popular CSMA/CA adopted in IEEE 802.11 will add more security even the key for encryption/decryption is already exposed. Because the overhead of CJWN is …

Comparative Performance Analysis of Cryptographic Workloads Across Cloud Providers: A Multi-Language Study on FaaS and IaaS Platforms Dataset
… including SHA HMAC generation, AES encryption/decryption, ECC signature/verification, and RSA encryption/decryption, across Function-as-a-Service (FaaS) and Infrastructure-as-a-Service (IaaS) in conjunction with KMS offerings from Ama- zon Web Services (AWS) and Microsoft Azure to conduct a …

Cryptographically enforced access control for user data in untrusted clouds
… store, and by default, only the user knows the decryption keys. Given this storage model, Sieve defines an infrastructure to support rich, legacy web applications. Using attribute-based encryption, Sieve allows users to define intuitive, understandable access policies that are cryptographically …

DeviceGuard: External Device-Assisted System And Data Security
… integrity monitoring, secure signing and secure decryption. We use Bluetooth as the communication protocol between the host and the Trusted Device. Our experiment results indicates a practical Bluetooth throughput at about 2M Bytes per second is sufficient for short range communication between …

Providing Location Security in Vehicular Ad Hoc Networks
… location integrity. We propose both encryption/decryption and access control mechanisms to provide location information confidentiality. The aggregated position message is encrypted by a key which is a geographic location which specifies a decryption region. Vehicles have to be physically …

From client-side encryption to secure web applications
… To ensure an adversary cannot gain access to the decryption keys or plaintext data, CryptFrame provides a browser extension that stores the keys and allows only sensitive regions in the web page to access them. CryptFrame performs templatized verification of sensitive regions to grant small …

Building practical systems that compute on encrypted data
… compute on encrypted data, without access to the decryption key. In this setting, we designed and built a database system (CryptDB), a web application platform (Mylar), and two mobile systems, as well as developed new cryptographic schemes for them. We showed that these systems support a wide …

Succinct garbled RAM from indistinguishablity obfuscation
… using the fact that the encryption and decryption keys can be separately punctured. This succinct garbling scheme serves as a drop-in replacement for the ubiquitous garbled circuits of Yao, but with better asymptotic parameters. In some cases, these improved parameters allow …

Adaptive Encryption Techniques In Wireless Communication Channels With Tradeoffs Between Communication Reliability And Security
… (sac), this error propagates during the decryption process, resulting in half the bits (on average) after decryption to be in error. In order to alleviate this amount of error, smart coding techniques and/or new encryption algorithms that take into account the nature of wireless channels …
