Security Notions Sample Clauses

Security Notions. This section introduces different security notions. Most of it is standard and it is taken from the literature. It first recalls the notion of indistinguishability un- der chosen ciphertext attacks for an encryption scheme and the notion of strong existential unforgeability under chosen message attacks for a signature scheme. Then we propose a new security definition for ETP protocols that capture real- istic threats that have not been considered in previous security definitions from the literature.

Security Notions i Session IDS and Partnering. Following [16], we defines session IDS and part- xxxxxx. The session IDS (SIDS) for an oracle Πs is defined as SIDS(Πs)=(SIDij), where XXXxx is the concatenation of all messages sent and received by an oracle Πs during the execution. The partner ID for an oracle Πs, denoted by PIDS(Πs), is a set of the identities of the users with whom Πs intends to establish a session key. Instances Πs and Πt are partnered if and only if PIDS(Πs)=PIDS(Πt) i j i j and SIDS(Πs)=SIDS(Πt). The presented notion of parting is simple since all

Security Notions. The usual security model [25] built on prior work from the two-party setting [26] [27] has been widely used to analyze group key agreement protocol. In this model, several queries are available to the attacker to model his capability. We will use the model to discuss the security of our proposed protocol. We assume that the users in set S = {A, B, C} will negotiate a session key using the key agreement protocol. An attacker can make following three queries. By accessing to the following oracles, Xxxxx can get, modify and replay the messages transmitted over the Internet. ⎯ Send (U , m) query. Xxxxx issues a query on (U , m) . Xxxxx is allowed to modify or replay any message he got from the answer of the query in active attack model.
