WebThe main weakness exists because PKCS#1 padding enabled some assumptions to be made. Those assumptions then can be exploited to design an attack. Check the paper, it's a clever attack! The attack is built in 4 stages, each stage progressively extracting more information than the previous. WebSummary Weaknesses in this category are related to the design and implementation of data confidentiality and integrity. Frequently these deal with the use of encoding techniques, encryption libraries, and hashing algorithms. The weaknesses in this category could lead to a degradation of the quality data if they are not addressed. Membership Notes
