- Summary
- Observable Timing Discrepancy in Tink-Java and Tink-Android ChunkedMacVerification
- Details
-
When verifying a mac with a ChunkedMacVerification object, Tink compares the resulting tag with non constant time comparison. This potentially allows an attacker to use timinig information as a side channel in order to get information how many bytes of a given tag match the correct tag. This in turn could allow to find a correct tag bytewise.
