Interestingly, none of these have been practically evaluated. We accomplished this task and prove that fault attacks against pairing-based cryptography are indeed possible and are even practical — thus posing a serious threat. Moreover, we successfully conducted a second-order fault attack against an open source implementation of the eta pairing on an AVR XMEGA A1. We injected the first fault into the computation of the Miller Algorithm and applied the second fault to skip the final exponentiation completely. We introduce a low-cost setup that allowed us to generate multiple independent faults in one computation. The setup implements these faults by clock glitches which induce instruction skips. With this setup we conducted the first practical fault attack against a complete pairing computation."}],"status":"public","file":[{"success":1,"relation":"main_file","content_type":"application/pdf","file_size":437518,"access_level":"closed","file_id":"1336","file_name":"463-FDTC14.pdf","date_updated":"2018-03-16T11:20:54Z","creator":"florida","date_created":"2018-03-16T11:20:54Z"}],"_id":"463","project":[{"_id":"1","name":"SFB 901"},{"name":"SFB 901 - Subprojekt C1","_id":"13"},{"_id":"4","name":"SFB 901 - Project Area C"},{"name":"Securing the Financial Cloud","_id":"43"}],"department":[{"_id":"64"}],"user_id":"25078","ddc":["040"],"file_date_updated":"2018-03-16T11:20:54Z"},{"citation":{"chicago":"Jochheim, Janek. <i>Hiding Software Components Using Functional Encryption</i>.

Our approach is to extend certain concrete chosen-plaintext secure (CPA-secure) ABE schemes to achieve more efficient constructions than the known generic constructions of CCA-secure ABE schemes. We restrict ourselves to the construction of attribute-based key encapsulation mechanisms (KEMs) and present two concrete CCA-secure schemes: a key-policy attribute-based KEM that is based on Goyal's key-policy ABE and a ciphertext-policy attribute-based KEM that is based on Waters' ciphertext-policy ABE. To achieve our goals, we use an appropriate hash function and need to extend the public parameters and the ciphertexts of the underlying CPA-secure encryption schemes only by a single group element. Moreover, we use the same hardness assumptions as the underlying CPA-secure encryption schemes.","lang":"eng"}],"type":"preprint"},{"title":"Attributbasierte Verschlüsselung mittels Gittermethoden - Mathematische Grundlagen, Verfahren und Sicherheitsbeweise","supervisor":[{"first_name":"Johannes","id":"23","full_name":"Blömer, Johannes","last_name":"Blömer"}],"date_created":"2017-10-17T12:42:40Z","author":[{"first_name":"Kathlén","last_name":"Kohn","full_name":"Kohn, Kathlén"}],"publisher":"Universität Paderborn","date_updated":"2022-01-06T07:01:57Z","citation":{"bibtex":"@book{Kohn_2013, title={Attributbasierte Verschlüsselung mittels Gittermethoden - Mathematische Grundlagen, Verfahren und Sicherheitsbeweise}, publisher={Universität Paderborn}, author={Kohn, Kathlén}, year={2013} }","mla":"Kohn, Kathlén. <i>Attributbasierte Verschlüsselung mittels Gittermethoden - Mathematische Grundlagen, Verfahren und Sicherheitsbeweise</i>.
