Key Exposure Resistant Group Key Agreement Protocol
2021With the development of the Internet and computer science, the demand for collaboration over the Internet is constantly increasing. The group key agreement (GKA) protocol has been a desirable candidate for this demand. However, the possibility that some parties in the GKA protocol may be tampered with by the adversary leads to the stronger requirement ...

Securing Cloud Data Under Key Exposure
IEEE Transactions on Cloud Computing, 2019Recent news reveal a powerful attacker which breaks data confidentiality by acquiring cryptographic keys, by means of coercion or backdoors in cryptographic software. Once the encryption key is exposed, the only viable measure to preserve data confidentiality is to limit the attacker's access to the ciphertext.

Chameleon Hashing Without Key Exposure
2004Chameleon signatures are based on well established hash-and-sign paradigm, where a chameleon hash function is used to compute the cryptographic message digest. Chameleon signatures simultaneously provide the properties of non-repudiation and non-transferability for the signed message, i.e., the designated recipient is capable of verifying the validity ...

Neural effects of controllability as a key dimension of stress exposure
Development and Psychopathology, 2022AbstractCross-species evidence suggests that the ability to exert control over a stressor is a key dimension of stress exposure that may sensitize frontostriatal-amygdala circuitry to promote more adaptive responses to subsequent stressors. The present study examined neural correlates of stressor controllability in young adults.

Reducing the Spread of Damage of Key Exposures in Key-Insulated Encryption
2006A proposal for key exposure resilient cryptography called, key-insulated public key encryption (KIPE), has been proposed by Dodis, Katz, Xu, and Yung [6] in which the secret key is changed over time so that the exposure of current key minimizes the damage overall.

Distal Facial Nerve Exposure: A Key to Partial Parotidectomy
Otolaryngology–Head and Neck Surgery, 2008Objective1) Learn techniques and outcomes of distal facial nerve identification compared with antegrade exposure in partial parotidectomy. 2) Be able to incorporate other modifications of parotidectomy facilitated by distal facial n. isolation including preservation of the greater auricular nerve, superficial musculo‐aponeurotic system (SMAS), and ...

Protecting Against Key Escrow and Key Exposure in Identity-Based Cryptosystem
2007Standard identity-based cryptosystems typically rely on the assumption that secret keys are kept perfectly secure. However, in practice, there are two threats to the key security in identity-based cryptosystems. One inherent problem is key escrow, that is, the Key Generation Center (KGC) always knows a user's secret key and the malicious KGC can ...
