In order to enable an iCal export link, your account needs to have an API key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.
Additionally to having an API key associated with your account, exporting private event information requires the usage of a persistent signature. This enables API URLs which do not expire after a few minutes so while the setting is active, anyone in possession of the link provided can access the information. Due to this, it is extremely important that you keep these links private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately create a new key pair on the 'My Profile' page under the 'HTTP API' and update the iCalendar links afterwards.

In this talk we propose an efficient code-based cryptosys-
tem with no hidden trapdoor in the public matrix. The system is in the
spirit of a system proposed by Alekhnovich in 2003 based on random
matrices, but still our approach is slightly different and optimized in or-
der to obtain security reduction to decoding random quasi-cyclic codes.
Beside a security proof we also provide a detailed analysis of the decryp-
tion failure probability of our scheme. Our scheme benefits from a very
fast decryption algorithm and has small sizes of public key with only a
few thousand bits. The encryption is rather low but our system can be
very efficient for key exchange and authentication. We also generalize
our approach to rank metric for which we obtain even better parameters
than for Hamming metric.
