Abstract
There is provided an apparatus which is a first apparatus, configured to communicate with at least one second apparatus via sidelink resources associated with unmodified sidelink control information, the apparatus comprising means for: detecting a possibility of a malicious attack on the sidelink resources or receiving an instruction to modify a sidelink control information message; transmitting, to the at least one second apparatus, a modified sidelink control information message indicative of at least one secret indication.
Claims18
An apparatus which is a first apparatus, comprising:
- at least one processor;
- and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to:
- communicate with at least one second apparatus via sidelink resources associated with unmodified sidelink control information;
- detect a possibility of a malicious attack on the sidelink resources or receiving an instruction to modify a sidelink control information message;
- and
- transmit, responsive to the detecting of the possibility of the malicious attack or to the receiving of the instruction, to the at least one second apparatus, a modified sidelink control information message indicative of at least one secret indication, wherein the at least one secret indication is indicative of a secret sidelink resource allocation, wherein the secret sidelink resources are different from the sidelink resources associated with the unmodified sidelink control information.
An apparatus which is a second apparatus, comprising:
- at least one processor;
- and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to:
- communicate with a first apparatus via sidelink resources associated with unmodified sidelink control information;
- and
- receive, from the first apparatus, a modified sidelink control information message indicative of at least one secret indication, wherein the at least one secret indication is indicative of a secret sidelink resource allocation, wherein the secret sidelink resources are different from the sidelink resources associated with the unmodified sidelink control information.
A method comprising:
- detecting, by a first apparatus caused to communicate with at least one second apparatus via sidelink resources associated with unmodified sidelink control information, a possibility of a malicious attack on the sidelink resources or receiving an instruction to modify a sidelink control information message;
- transmitting, responsive to the detecting of the possibility of the malicious attack or to the receiving of the instruction, to the at least one second apparatus, a modified sidelink control information message indicative of at least one secret indication, wherein the at least one secret indication is indicative of a secret sidelink resource allocation, wherein the secret sidelink resources are different from the sidelink resources associated with the unmodified sidelink control information.
A non-transitory computer readable medium comprising program that, when executed by an apparatus, cause the apparatus to perform at least the following:
- detecting, by the first apparatus caused to communicate with at least one second apparatus via sidelink resources associated with unmodified sidelink control information, a possibility of a malicious attack on the sidelink resources or receiving an instruction to modify a sidelink control information message;
- transmitting, responsive to the detecting of the possibility of the malicious attack or to the receiving of the instruction, to the at least one second apparatus, a modified sidelink control information message indicative of at least one secret indication, wherein the at least one secret indication is indicative of a secret sidelink resource allocation, wherein the secret sidelink resources are different from the sidelink resources associated with the unmodified sidelink control information.
