The proof of [17] is valid for chosen-ciphertext attacks (CCAs) us-ing q≪ 2n/2 queries, and is called a proof of O(2n/2)-security. As 2n/2 is related to the birthday paradox for n-bit variables, it is also called the security up to the birthday bound (for n). Then, building a DBLC having beyond-birthday-bound

WebJan 26, 2014 · Birthday Attack A birthday attack is a class of brute force attack used against hashing functions. It is based on the "birthday paradox." This states that in a group of 23 people, there is at least a 50% probability that at least two people will share the same birthday. In a group of 60 people, the probability is over 99%.

"A birthday attack is a type of cryptographic attack that exploits the mathematics behind the birthday problem in probability theory. This attack can be used to abuse communication between two or more parties.
